(Point of interest)
General large- and medium-scale farms in the pig farming industry in Japan consist of a breeding piggery, a piggery piggery, a weaning piggery and a fattening piggery. After becoming fattened pigs through the process, they are moved from the weaning pigsty to the fattening pigsty, fattened to the shipping weight in the fattening pigsty, and then shipped. In the pig farming method used, it is essential to move pigs from the farrowing pigsty to the weaning pigsty and from the weaning pigsty to the fattening pigsty in the process of growth. Due to various stresses, such as the stress caused by the confluence and the struggles that result from it, it takes time to recover. ) had the drawback of making it difficult to prevent infectious diseases due to the merging of different herds.

As a technique to reduce stress and prevent infectious diseases caused by moving between piggeries and joining groups, weaned piglets are moved from the birthing piggery to the piggery for weaning and fattening at the same time as weaning, and then moved to shipping. In recent years, piggeries that enable win-to-finish (WtoF) and all-in-all-out (AI/AO) techniques have been adopted so that pigs can be raised without being forced to do so. Piglets that are weaned at less than 120 kg are placed in a large piggery that can handle pigs with a shipping weight of about 120 kg, so the piggery floor area required for the piglet breeding period of the weaned piglets is less than that of conventional weaning. It was larger than the pigsty, and the burden of the facility cost was an issue.

(conventional technology)
Reflecting this situation, it is not that there have not been some proposals that could serve as breakthrough measures.
For example, as typified by the one proposed in Patent Document 1 (1) below, a large room (large pig box) for breeding multiple heads and poor growth connected to the large room (large pig box) It consists of two small rooms (small pig compartments) for pigs and obese pigs, and between the large room (large pig compartment) and each small compartment (small pig compartment), there is an iron grate that is opened and closed by the administrator. A see-through door is provided, and a toilet and a water dispenser are installed at the connection between the large room (large pig room) and each small room (small pig room), and the large room (large pig room) and each A feeder is provided in each small room (small pig box), a group of weaned piglets is housed in a large room (large pig box), and pigs with poor growth due to growth are placed in a small room for poor growth pigs (small pig box). The obese pigs are moved to a small room for obese pigs (small pigs), the transparent door is closed and isolated, and the large room (large A tying piggery that enables Vienna to Finish (WtoF) while reducing the number of pigs in a piggery) and ensuring a large floor space per pig, as seen in Patent Document 1 (2). A large room for rearing multiple pigs (large pig compartment) is provided on one side of the central passage, and two small compartments (small pig compartment) for stunted pigs and obese pigs are provided on the other side. ), toilets are provided on the opposite side of the passage of each room (pig pen) to make it a both-sided urine collection system and air is introduced from the central passage, and the side wall is compared to the conventional pigsty from the central passage. The number of pigs is reduced, the construction cost is reduced, and water supply and feeding are possible along the central passage, which facilitates management. There are some tying piggeries that can prevent pigs from falling.

However, the tying piggeries as shown in the former patent document 1 (1) and the latter patent document 1 (2) enable win-to-finish (WtoF), but all-in The structure is not based on the premise of all-out (AI / AO), and pigs with different ages come into contact in the piggery, so there is a high risk of disease problems occurring. When all-in/all-out (AI/AO) is performed, a large number of subdivided rooms are required, resulting in an increase in construction costs and a steep rise in management costs.

(problem awareness)
As mentioned above, each piggery that enables Vienna to Finish (WtoF), which has been proposed so far, is shipped after the weaning and rearing period of the weaned piglet group, or the meat pig fattening period after becoming a fattening pig group. From the beginning of weaning piglets until they reach weight and become a shipping herd, we have no choice but to secure the same floor area as fattening pigs from the beginning. Installing the insulation and heating equipment that is essential for raising weaned piglets in the entire weaning and fattening room requires more equipment costs than a conventional piggery. A part of the room is partitioned with a partition fence to enclose the floor area necessary for raising weaned piglets, and heat insulation and heating equipment are installed only within that area, and the installation cost of the heating equipment and the utility costs required for its operation Even if it is possible to suppress the piglets, the remaining floor space divided by the partition fence cannot be used effectively until the weaned piglet herd becomes a fattening pig herd, and it becomes a waste of space. By eliminating these drawbacks of conventional piggeries, it is possible to more efficiently install various facilities such as heat insulation/heating equipment, water supply/feeders, etc. by avoiding enlargement of piggeries. Furthermore, when the conventional piggery was developed, the variation in pig development was large, and it was not an environment where all-in-all-out (AI / AO) breeding could be done efficiently. Due to the fact that the variation in pig growth has been improved and efficient breeding by all-in-all-out (AI/AO) has become possible, the Vienna to Finish (WtoF) and all-in A new piggery that realizes all-out (AI / AO), efficiently reduces the required floor space, and greatly reduces running costs for construction and equipment costs, utility costs, and maintenance management, and This made me keenly aware of the possibility of developing a new pig farming method using it.

(Purpose of Invention)
Therefore, the present invention avoids enlarging the pigsty, makes it possible to more efficiently arrange various facilities such as heat insulation / heating equipment, water supply / feeder, and more efficient Vienna to finish (WtoF) and Judging that it would be possible to develop a new piggery technology that can realize all-in-all-out (AI/AO), we quickly started research and development, and after many trials and errors over a long period of time. , As a result of investing new construction costs to prototype a new type of piggery and experimenting with a new pig farming method, this time, finally realizing a piggery with a new structure and a new pig farming method using it. In the following, the configuration will be described in detail together with an embodiment representing the present invention shown in the drawings.

(Composition of the invention)
As can be clearly understood from the embodiments representing the present invention shown in the drawings, the pigsty of the present invention basically consists of the following construction.
That is, a first WtoF room having a floor space for accommodating a certain number of preceding weaned piglets is provided, and the total floor area of the first WtoF room is the same as the number of preceding weaned piglets. A alternating fattening room having a floor space for housing a fattening pig herd is adjacent to the first WtoF room and the alternating fattening room so as to be openable and closable via a first movable wall that can be closed to seal and open to communicate, For the alternating fattening room, the second WtoF room, which has the same number of floor areas as the preceding weaned piglet herd and accommodates the same number of subsequent weaned piglets, closes, seals, and opens the alternating fattening room and the second WtoF room. The three rooms of the first WtoF room, the alternating fattening room and the second WtoF room constitute one WtoF unit, and at least one of the WtoF units is It is a piggery whose gist is that it is installed indoors.

In other words, the pigsty consisting of this basic configuration is provided with a first WtoF room that has a floor space for accommodating a certain number of pre-weaned piglets, and is combined with the first WtoF room. The alternating fattening room, which has a floor area that accommodates the same number of the preceding fattening pig herds as the preceding weaned piglet herd, closes, seals, and opens the first WtoF room and the alternating fattening room. A second WtoF room that is openable and closable adjacent to the alternating fattening room via a communicable first movable wall and has a floor space for accommodating the same number of subsequent weaned piglets as the preceding weaned piglet herd. is openable and closable adjacent to the alternating fattening room and the second WtoF room via a second movable wall that can be closed and sealed and open and communicated, and the first WtoF room, the alternating fattening room and the second WtoF room are arranged. A room constitutes one WtoF unit, at least one of the WtoF units is installed indoors, and while reasonably suppressing the accommodation floor space of the preceding weaning piglet herd and the subsequent weaning piglet herd, Vienna to Finish (WtoF) and all-in/all-out (AI/AO).

More specifically, a first WtoF room is provided in which a floor area for accommodating a certain number of 30 to 2400 pre-weaned piglets is provided, and the floor area combined with the first WtoF room is the above-mentioned pre-weaned piglets. The alternating fattening room, which has a floor space for accommodating the herd of preceding fattening pigs of the same number as the herd of pigs, has a first movable wall that allows the first WtoF room and the alternating fattening room to close and seal and open to communicate. A second WtoF room is adjacent to the alternating fattening room so that it can be opened and closed, and has a floor space for accommodating the same number of subsequent weaned piglets as the preceding weaned piglet herd. The 2WtoF rooms are openable and closable adjacent to each other via a second movable wall that can be closed and sealed and open and communicated, and the three rooms of the first WtoF room, the alternating fattening room and the second WtoF room form one WtoF unit. None, at least one of the WtoF units will be a piggery constructed indoors.

The present invention also includes a method for raising pigs using the pigsty, which is the basis of the present invention described above.
That is, the first movable wall and the second movable wall are hermetically closed, the first WtoF room, the alternating fattening room and the second WtoF room are each independent rooms, and the first WtoF room is preceded by a certain number of animals of 3 to 15 kg/head. A weaned piglet herd is housed and piglet rearing is started, and when the preceding weaned piglet herd becomes a pre-fattening pig herd weighing 45 to 60 kg/head, the first movable wall is opened to allow free passage, and the The first WtoF room and the alternating fattening room are connected to form one fattening room. A certain number of subsequent weaned piglet herds of 3 to 15 kg/head are housed in a 2WtoF room, piglet rearing is started, and all piglets of the preceding fattening herd that have reached a weight of 110 kg/head or more are shipped. After cleaning and disinfecting the 1WtoF room and the alternating fattening room and hermetically closing the first movable wall, a new pre-weaned piglet herd of a certain number of 3 to 15 kg/head is housed in the 1WtoF room. When rearing is started and the subsequent weaned piglet herd becomes a subsequent fattening pig herd with a body weight of 45 to 60 kg/head, the second movable wall is opened to allow free passage, and the second WtoF room and alternating fattening room are connected. , starting meat pig fattening of the subsequent fattening pig group as one fattening room, shipping all the pigs of the subsequent fattening pig group that have reached a weight of 110 kg / head or more, and the second WtoF room and alternating fattening. After cleaning and disinfecting the room and sealingly closing the second movable wall, a certain number of new subsequent weaned piglets are housed in the same second WtoF room to start raising the piglets, and the above series of steps are performed. It is a pig farming method using the piggery that forms the basis of the present invention, which is permanently repeated.

To express this pig farming method in a different way, the first movable wall and the second movable wall are hermetically closed, the first WtoF room, the alternating fattening room and the second WtoF room are each independent rooms, and the first WtoF room A certain number of preceding weaned piglets are housed and piglet rearing is started, and 11 to 14 weeks after the start of piglet rearing of the preceding weaning piglet group, a certain number of subsequent weaning piglets are placed in the second WtoF room. The herd is accommodated and piglet rearing is started, the preceding weaned piglet herd becomes the preceding fattening pig herd 11 to 14 weeks after the start of piglet rearing, the first movable wall is opened to allow free passage, and the first WtoF. A room and a alternating fattening room are connected to form one fattening room, and fattening of the preceding fattening pig group is started, and 11 to 14 weeks after the start of fattening of the preceding fattening pig group ( 22 to 28 weeks after the start of piglet rearing), all heads of the same pre-fattening pig herd are shipped, the first WtoF room and alternating fattening room are cleaned and disinfected, and the first movable wall is removed. A new pre-weaned piglet herd of a certain number was housed in the first WtoF room of the same closed and closed to start piglet rearing, and the subsequent weaned piglet herd was subjected to subsequent fattening 11 to 14 weeks after the start of piglet rearing. A pig herd is formed, the second movable wall is opened to allow free passage, the second WtoF room and the alternating fattening room are connected to form one fattening room, and fattening of the subsequent fattening pig herd is started. Within 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) after the start of meat pig fattening of the subsequent fattening pig herd, all the pigs of the subsequent fattening pig herd are shipped, After cleaning and disinfecting the 2WtoF room and the alternate fattening room and hermetically closing the second movable wall, a certain number of new subsequent weaned piglets were housed in the 2WtoF room to start raising the piglets. It can be said that the pig farming method using the aforementioned piggery forming the basis of the present invention, in which the series of processes of (1) is permanently repeated.

More specifically, this pig farming method is described by hermetically closing the first movable wall and the second movable wall, making each of the first WtoF room, the alternating fattening room and the second WtoF room independent rooms, and in the first WtoF room A pre-weaned piglet herd of a certain number of 3 to 15 kg/head is housed and piglet rearing is started, and the body weight of the pre-weaned piglet herd reaches 45 weeks 11 to 14 weeks after the piglet rearing is started. When the pre-fattening pig group reaches 60 kg/head, the first movable wall is opened so that the pigs can freely pass through, fattening of the pre-fattening pig group is started, and fattening of the pre-fattening pig group is started. At the same time, a certain number of subsequent weaned piglet herds of 3 to 15 kg/head are housed in the second WtoF room, piglet rearing is started, and the preceding fattening pigs that have reached a weight of 110 kg/head or more are shipped in order. After 11 to 14 weeks from the start of fattening (22 to 28 weeks from the start of piglet rearing), all the pigs in the preceding fattening group have been shipped, and the first WtoF room and After washing and disinfecting the alternating fattening room and hermetically closing the first movable wall, a new pre-weaned piglet group of a certain number of 3 to 15 kg/head is housed in the first WtoF room to start piglet rearing. Then, when 11 to 14 weeks have passed since the start of piglet rearing of the subsequent weaned piglet herd, and the subsequent fattening piglet herd weighed 45 to 60 kg/head, the second movable wall was made freely passable. Open, connect the second WtoF room and the alternate fattening room to form one fattening room, and start the meat pig fattening of the subsequent fattening pig herd, and from the subsequent fattening pig whose weight has reached 110 kg / head or more. Shipped in order, until 11 to 14 weeks after the start of meat pig fattening (22 to 28 weeks after the start of piglet rearing), all the pigs of the same subsequent fattening pig herd have been shipped, and the second WtoF After cleaning and disinfecting the room and the alternate fattening room and hermetically closing the second movable wall, a new subsequent weaned piglet herd of a certain number of 3 to 15 kg/head is housed in the second WtoF room to raise the piglets. It can be said that it is a pig farming method using the piggery that forms the basis of the present invention, in which the above series of processes are permanently repeated.

As described above, according to the piggery and the pig farming method using the same of the present invention, when using conventional weaning piggeries and fattening piggeries, conventional win-to-finish (WtoF) and all-in-all Compared to out (AI / AO) piggeries, the construction area can be kept small, but there is a drawback that the workability of breeders such as moving between piggeries is poor. ) and all-in-all-out (AI/AO) piggeries improve the workability of breeders, but have the drawback of increasing the construction area and increasing construction and equipment costs. When a piggery equipped with the WtoF unit of the invention is constructed, it is possible to reduce the floor area of the piggery to about 3/4, unlike the conventional ones, due to the above-mentioned unique characteristic configuration. In addition, the 1st WtoF room and the 2nd WtoF room for housing the weaned piglet herd are provided separately from the alternating fattening room that is connected when the fattening piglet herd is fattened. The installation range of is limited to the 1st WtoF room and the 2nd WtoF room, and the facilities such as weight scales necessary for meat pig fattening are installed in the alternating fattening room, so that the fattening of the 1st WtoF room and the 2nd WtoF room Pig herds can share facilities for fattening pigs at different times, which makes it possible to significantly reduce the construction, maintenance, and management costs of piggeries. Vienna-to-finish (WtoF) and all-in-all-out (AI/AO) pigsties can be suppressed to approximately the same extent as in pigsties, and after weaning piglets are moved to the pigsties of this invention, they are kept in the pigsties until shipping. There is no need to move between pigs, and the stress associated with moving can be minimized. Subsequent weaned piglet herds, kept in close isolation without joining other herds and housed in the 2nd WtoF room, are also separated from other herds until they develop into subsequent fattening herds of shipping weight. Because it does not join the crowd and maintains a densely isolated state, it is possible to achieve Vienna to Finish (WtoF) and All-In-All-Out (AI/AO) more efficiently, and other In addition to eliminating the occurrence of fighting due to joining with the herd, it is possible to more effectively prevent the occurrence of infectious diseases, and it is possible to obtain excellent characteristics that it is possible to realize remarkably economical and high-quality pig farming. be.

In addition, a first WtoF room is provided in which a floor area is secured to accommodate a certain number of 30 to 2400 pre-weaned piglet herds, and the floor area combined with the WtoF room is the number of the pre-weaned piglet herds. A 2nd WtoF room where the alternating fattening room with the same floor area as the preceding weaned piglet herd is provided, and the floor area is secured to accommodate the same number of subsequent weaned piglet herds as the preceding weaned piglet herd According to the piggery of the present invention and the pig farming method using the same, by accommodating 30 or more piglets, more economical breeding is possible, and accommodation of the preceding weaning piglet group and the subsequent weaning piglet group The more the number of pigs is increased, the more the economic effect can be enhanced. However, these drawbacks can be eliminated, the economic effect can be maximized, and more efficient pig farming can be realized.

Then, the first WtoF room and the second WtoF room are set to a floor area of 0.35 to 0.72 m ² /head, respectively, and the first WtoF room and the alternating fattening room, the alternating fattening room and the second WtoF room However, according to the piggery of the present invention, which is set to a floor area of 0.7 to 1.2 m ² /head, the maximum pig farming effect can be obtained with a minimum floor area. A highly productive piggery can be constructed on a narrower site at a lower cost.
Furthermore, according to the piggery of the present invention, each of the first WtoF room and the second WtoF room is partially provided with an auxiliary living room provided with heat insulating equipment and heating equipment for raising piglets, Compared to traditional win-to-finish (WtoF) and all-in-all-out (AI/AO) piggeries, the insulation and heating equipment for raising piglets can be significantly reduced, making it more economical. It will be able to be constructed and maintained.

In addition, during the fattening of the fattening herd, the one-way is arranged so that it cannot reach either the feeder or the waterer unless it passes through an automatic weighing and sorting device having a weighing unit and an automatic sorting unit. - According to the pigsty of this invention having a partition fence provided with a gate, fattening pigs move in search of either the feeder or the waterer according to the physiological phenomenon of either hunger or thirst. In the meantime, the automatic weight measurement / sorting device weight scale is entered, the weight is automatically measured by the same weight measurement unit, and the fattened pigs that have reached the shipping weight by the same automatic sorting unit are shipped in each variable shipping pig bunch. A fattening pig that has not yet reached its shipping weight is automatically guided to a variable shipping pig pen that has been made into a pig pen, and is guided to either the first movable wall or the second movable wall, whichever is open, and thus The fattening pigs left unshipped are hungry or thirsty, so they go through the one-way gate for either food or water and reach either the feeder or the waterer, Again, the fattening pigs, either hungry or thirsty, were transferred to the automatic weighing and sorting scale for either a feeder or a waterer on a daily basis. This is repeated multiple times, and fattened pigs that have reached the shipping weight are automatically gathered in a variable shipping pig box without stress, without the assistance and guidance of breeders. As a result, it is possible to greatly reduce the man-hours of the shipping work of the keepers.

A pre-weaned piglet herd of a certain number of 3 to 15 kg/head was housed in the first WtoF room, piglet rearing was started, and the pre-weaned piglet herd became a pre-fattening pig herd weighing 45 to 60 kg/head. At this time, the first movable wall is opened to allow free passage, the first WtoF room and the alternate fattening room are connected to form one fattening room, and fattening of the pre-fattening pig herd is started, and the pre-fattening pig is started. At the same time as the start of meat pig fattening of the herd, a certain number of subsequent weaned piglets of 3 to 15 kg/head were housed in the second WtoF room and piglet rearing was started, and the weight reached 110 kg/head or more. According to the pig farming method using the piggery of the present invention, in which all the pigs in the pre-fattening herd are shipped, the pigs are raised to 20 to 40 kg/head (about 30 kg/head) in a conventional weaning house, and then fattened. Compared to the conventional pig farming method in which the pigs are moved to a barn and fattened until they reach a weight of 110 kg/head or more before being shipped, there is no need to move between piggeries from weaning to shipping, and it is possible to join with another herd. In addition, it is possible to prevent the occurrence of unnecessary stress and struggle due to it by eliminating the merging of pigs with a herd with a large age difference, prevent the occurrence of infectious diseases, and realize more efficient pig farming.

A certain number of preceding weaned piglet herds are housed in the first WtoF room and piglet rearing is started, and 11 to 14 weeks after the start of piglet rearing of the preceding weaning piglet group, a certain number of following piglets are placed in the second WtoF room. A herd of weaned piglets is accommodated and rearing of piglets is started, and the pre-weaned piglet herd becomes a pre-fattening pig herd 11 to 14 weeks after the start of piglet rearing, and the first movable wall is opened to allow free passage, and said The first WtoF room and the alternating fattening room are connected to form one fattening room, and fattening of the pigs of the pre-fattening pig group is started, and 11 to 14 after the fattening of the pigs of the pre-fattening pig group is started. After a week (22 to 28 weeks from the start of piglet rearing), all the heads of the preceding fattening pig herd are shipped. By shifting the start time of piglet rearing from the subsequent weaned piglet group by 11 to 14 weeks, the alternating fattening room can be used during the fattening of the piglets of the pre-fattening pig group, and the subsequent fattening. Immediately before fattening of the pig herd starts, it is the timing when all the pigs of the preceding fattening pig herd have been shipped. Since fattening of meat pigs can be started, the preceding fattening pig group and the subsequent fattening pig group alternately use the alternating fattening room, and the floor area of the alternating fattening room is reduced by about one unit. , It can be a miniaturized WtoF unit, significantly reducing the construction cost of the piggery and the equipment cost associated with it, and conventional Vienna to finish (WtoF) and all-in-all-out (AI / AO) can achieve the same production efficiency as the pigsty.

The first movable wall and the second movable wall are hermetically closed, the first WtoF room, the alternating fattening room and the second WtoF room are each independent rooms, and the first WtoF room contains a certain number of preweaners of 3 to 15 kg/head. When a pig herd is housed and piglet rearing is started, and the pre-weaned piglet herd becomes a pre-fattening pig herd weighing 45 to 60 kg/head 11 to 14 weeks after the start of piglet rearing. , open the first movable wall to allow free passage, start fattening of the pigs of the preceding fattening pig group, and at the same time as the start of fattening of the pigs of the preceding fattening pig group, a certain number of 3 pigs are placed in the second WtoF room. or 15 kg/head of subsequent weaned piglet herds are accommodated and piglet rearing is started, and after the meat pig fattening of the preceding fattening pig herd is started, the preceding fattening pigs whose weight reaches 110 kg/head or more are shipped in order. Then, the shipment of all pigs in the preceding fattening herd is completed within 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) from the start of meat pig fattening. According to the pig farming method using the piggery, compared to the conventional Vienna-to-finish (WtoF) and all-in-all-out (AI/AO) piggeries, in piggeries with a reduced floor area , the same pig farming environment can be realized, so there is an effect that a pig farming technology with much lower construction costs and lower running costs can be realized.

In carrying out the present invention having the configuration as described above, the best or desirable mode will be explained.
The piggery shall share the functions of housing weaned piglets and allowing them to be weaned and fattened until they reach their shipping weight, and shall have at least one WtoF unit consisting of a first WtoF room, alternating fattening room and a second WtoF room. More specifically, as shown in the examples described later, the first WtoF room and the alternating fattening room are closed and hermetically sealed, and open and open and closable adjacent to each other via the first movable wall. , the second WtoF room must be openable and closable adjacent to the alternating fattening room via a second movable wall that can be closed and sealed, and can be opened and communicated. It is better to have a quarantine house, a piggery house, a delivery house, a shipping port, and excrement/urine treatment equipment, etc. on the premises of , not only for pig farming, but also for weaning or fattening other livestock and animals. It is possible to

In addition, in a large farm, for example, a breeding department consisting of a quarantine house, a breeding piggery, a farrowing house and manure processing equipment is installed at a first site, and a separate second site has a piggery and manure processing equipment of the present invention. separate fattening departments could be established, with the first and second sites cooperating for pig farming, and manure treatment facilities could be set up in separate separate dedicated facilities. However, the pigsty of the present invention can be installed in any type of farm.

The WtoF unit shares the functions that make it possible to realize the pig farming method using the piggery of the present invention, and from the combination of the first WtoF room, the alternating fattening room and the second WtoF room necessary to implement the pig farming method of the present invention. At least one WtoF unit must be installed in one pigsty, and multiple WtoF units can be installed in one pigsty. , the first WtoF room, the alternating fattening room and the second WtoF room can be arranged in any one of L, N, T, U, and Y shapes in plan view, and it will also be shown in the examples described later. As shown, the alternating fattening room is preferably sandwiched between the first WtoF room and the second WtoF room and arranged linearly (I-shaped in plan view) in the shape of a tenement.

The first WtoF room accommodates a certain number of pre-weaned piglet herds, enables piglets to grow in the pre-weaned piglet herds, and when these pre-weaned piglets grow into pre-fattening pig herds, , The first movable wall expands the floor area together with the connected alternating fattening room, has the function of making it possible to fatten the pre-fattening pig herd of a certain number, and houses the pre-weaned piglet herd of a certain number. A alternating fattening room with a secured area and a total floor area with the first WtoF room that accommodates the same number of pre-fattening pig herds as the number of the pre-weaned piglet herds. , The first WtoF room and the alternating fattening room must be openable and closable via a first movable wall that can be closed and sealed and can be opened and communicated, and the first WtoF room must be connected through a passage or the like. It is desirable to have the insulation and heating equipment necessary for raising piglets in winter. A chamber may be installed.

The alternating fattening room is divided into the first WtoF room and the first WtoF room when the second movable wall is closed and the first movable wall is opened when the preceding weaning piglet herd housed in the first WtoF room grows into a preceding fattening piglet herd. It is possible to form a large room in which a floor area suitable for fattening the preceding fattening pig herd is secured, and when the subsequent weaning piglet group housed in the second WtoF room grows into a subsequent fattening pig herd, When the first movable wall is closed and the second movable wall is opened, it is connected to the second WtoF room, sharing the function of forming a large room with a floor area suitable for fattening of the subsequent fattening pig herd. The floor area combined with the first WtoF room is the floor area for housing the same number of pre-fattening pig herds as the number of the preceding weaned piglet herds, and the floor area combined with the second WtoF room is the above-mentioned The floor area should be set to accommodate the same number of subsequent fattening pigs as the number of preceding weaning piglets. • It may have a sorting device, a variable shipping pen for the first WtoF room and a variable shipping pen for the second WtoF room.

The first movable wall has the function of allowing the first WtoF room and the alternating fattening room to be openable and closed, and in the closed state, pigs cannot come and go between the first WtoF room and the alternating fattening room. It is almost non-ventilated, and it is impossible for pigs to come into contact with each other across rooms, and it is possible to reliably prevent the airborne transmission of pathogens and the transfer of pathogens through nose contact between pigs. For example, it can be a panel or door made of resin, wood, metal, etc. If necessary, a transparent resin film or transparent resin panel can be placed at the height of the worker's line of sight. A closed window such as a window can be provided so that the state of the pig in the next room can be visually confirmed.

The second WtoF room accommodates a certain number of subsequent weaned piglet herds, allows piglets to grow in the subsequent weaned piglet herds, and when the subsequent weaned piglet herds grow into subsequent fattening piglets. , the first movable wall is closed, the second movable wall is opened, and the floor area is expanded together with the connected alternating fattening room, and the function is to enable fattening of the following fattening pig herd of a certain number. A floor area for housing a herd of weaned piglets is secured, and the floor area combined with the second WtoF room is a floor for housing a subsequent fattening pig herd of the same number as the number of the subsequent weaned piglet herd. The second WtoF room and the alternating fattening room must be openable and closable via a second movable wall that can be closed and sealed and open and communicated, or connected through a passage. In addition, the floor area should be secured to accommodate the same number of subsequent weaned piglet herds as the preceding weaned piglet herd housed in the first WtoF room, which is necessary for raising piglets in winter. It is desirable to have a heat insulation and heating facility, and as shown in the examples described later, an auxiliary living room equipped with heat insulation and heating equipment for raising piglets should be installed. can be done.

The second movable wall has the function of allowing the second WtoF room and the alternating fattening room to be openable and closed, and in the closed state, pigs cannot move between the second WtoF room and the alternating fattening room. In addition, it is hardly ventilated, and it is impossible for pigs to come into contact with each other across rooms. For example, it can be made of resin, wood, metal, etc. Panels and doors, etc., and if necessary, transparent resin film or transparent A closed window made of a resin panel or the like is provided so that the appearance of pigs in the adjacent room can be visually confirmed.

The heat insulation equipment provided in each of the first WtoF room and the second WtoF room has the function of insulating the inside and outside of the piggery so that the indoor temperature suitable for the growth of piglets can be secured even in the harsh winter. The ceiling, inner wall or outer wall must be partially or wholly provided with thermal insulation, for example, mineral fiber-based materials such as glass wool, rock wool, cellulose fiber, insulation board, etc. , phenolic foam, rigid urethane foam, extruded polystyrene foam, beaded polystyrene foam, polyethylene foam, and other natural materials such as recycled polyester materials, wool insulation materials, carbonized foam cork, vacuum insulation materials, and aluminum heat shield sheets. , recycled materials, new materials, etc., and the heating equipment provided in each of the WtoF unit and the second WtoF room can ensure a temperature suitable for growing piglets even in the harshest winter. Air conditioners, oil heaters, multi-dynamic heaters, panel heaters, kerosene fan heaters, kerosene stoves, so that at least a part of the 1st WtoF room and the 2nd WtoF room can be heated by sharing the function of intensively warming the piglets in the room. , Gas fan heaters, electric stoves, steam heaters, floor heating and other heating appliances may be installed, and humidity control equipment such as humidifiers and dehumidifiers should be installed.
The heat insulation equipment and heating equipment can be installed only in the auxiliary living cells provided in the first WtoF room and the second WtoF room, respectively, as shown in the examples described later. In the case of a pigsty built in a warm area where piglets can grow healthily even if they are left alone, the heat insulating equipment and the heating equipment can be completely removed.

When the doorway of the first partition and the first movable wall and the doorway of the second partition and the second movable wall are in a closed state, not only pigs' passage but also air flow is stopped and pathogens are prevented from entering. Even if it receives atmospheric pressure or is forced to decompress or pressurize air by a ventilation fan, It is desirable to be able to ensure airtightness between the fattening room and the second WtoF room in a state where air does not circulate. As a result, it was found that airborne infection of pathogens could be effectively prevented even if a small amount of air leakage was tolerated. If a closed structure with a relatively low airtightness such as a small gap is used, the advantage of reducing equipment costs can be obtained.

However, the first movable wall and the second movable wall can be in a closed state and strictly sealed, so a specific example will be mentioned. For example, a stepped portion is provided at the opening edge of each doorway, a sealing material made of elastic resin or natural fiber is interposed along the stepped portion, and either the first movable wall or the second movable wall is provided. , can be closed in a fitted and hermetically closed manner. In addition, a temporary structure is provided between the doorway and the outer peripheral edge of either the first movable wall or the second movable wall to prevent inadvertent opening. Locking means such as a hook or buckle for temporary fixing that can be fixed may be provided, or a close contact and airtight state may be achieved by sealing with adhesive tape or the like.

In addition, the doorway of the first partition and the first movable wall, and the doorway and the second movable wall of the second partition are formed in a planar shape so that the floor surface is barrier-free, as shown in the examples described later. In addition, even if there is a slight step on the floor, regardless of whether it is a weaned piglet or a fattening pig, it is possible to move over it, so for example, the floor surface of each entrance Even if there is a step of about 7 to 8 cm in height, it can be used without problems. It is possible to have a structure in which the outer peripheral edge of each movable wall is fitted to the endless peripheral edge and closed.

A weaned piglet herd is a herd of piglets that have been weaned from their sows, more specifically, fed in a farrowing piggery for 3 weeks (18 to 25 days) after birth and weighing 3 to 25. It can be said that it is a herd with a certain number of piglets that have grown up to 15 kg/head, and it can be said that it is a herd with a number of piglets that is either equal to or less than the number of piglets that can be accommodated in the first WtoF room (permissible number). The lead weaned piglet group is a group of piglets weaned 11 to 14 weeks later than the follower weaned piglet group. ) can be said to be either the same number of piglets or less than the number of piglets. The number of lead-fitter herds that can be accommodated in a fattening room should be equal to or less than the number of trailing piglet herds housed in the second WtoF room, and the number of trailing piglet herds housed in the second WtoF room and alternating fattening rooms. It can be said that it should be equal to or less than the number of possible subsequent fattening herds. However, if the number of piglets accommodated in each of the first WtoF room and the second WtoF room fluctuates in the number of production, a group of weaned piglets exceeding the planned number of piglets accommodated (permissible number) Therefore, the actual situation is that it is not possible to strictly limit the number of piglets. Sometimes the numbers are exceeded.

In other words, a weaned piglet herd receives lactation for 3 weeks (18 to 25 days) after parturition in a piggery, and weighs at least 3 kg/pig or more. It can be said that it is a herd of a certain number of piglets that have grown to 3 to 8 kg/head, or 4 to 15 kg/head, more specifically around 6 kg/head, and if the weight is less than 3 kg/head, weaning rearing is performed. For the health of the piglets, it is desirable to start weaning breeding when the piglet weighs 4 kg or more as much as possible. In addition to the problem of exhaustion and deterioration of the turnover rate of the farrowing barn, sows produce colostrum for about two days after parturition, and the antibody (immune substance) received from the colostrum differs depending on each disease. However, it wears off around 16 to 24 days after birth, and since normal milk after the colostrum is also slightly mixed with antibodies, the safety of piglets is ensured while they are breastfeeding. If the piglets are left in the farrowing barn without drinking, the piglets' immunity will be cut off, and there is a risk that the disease will spread to the piglets from the piggery that the mother pig has soiled. It is important to move the piglets to the breeding piggery and the piglets to the weaning barn. Head and back.

However, in Europe, legislation for animal welfare (animal protection) has progressed, and the weaning age is 28 days or older. There is also the possibility of reaching 14 kg/head. Furthermore, it can be said that it is basically impossible for piglets to be weaned over 15 kg/head and moved to the WtoF unit of the piggery of the present invention, except in irregular circumstances. The irregular situation is, for example, when a disease suddenly invades and the movement of pigs is temporarily stopped to deal with it, or when sudden construction is required in the piggery of the present invention immediately before weaning/moving. This is the case when the movement of the piglet is unavoidably stopped, and the growth progresses during that time.

Furthermore, the number of pigs to be accommodated in the first WtoF room or the second WtoF room is not rational both in terms of efficiency and economics, and it is not rational to carry out large group breeding with less than 30 pigs. is desirable, and if the number of pigs exceeds 2,400, the size of the piggery will become too large, and the strength and size of the roof will become a problem, and there is a risk that the construction cost will rather rise. Because thick pillars are required to support a large roof and each part is large, it is not possible to manufacture at a factory or assemble on site due to transportation reasons. The upper limit of the number of animals that can be handled is usually around 500 animals. Some Vienna to Finish (WtoF) piggeries alternately use weighing and sorting devices (auto sorters), so the maximum herd size is realistically 1,000 pigs, and with some ingenuity, it could be 2,000 pigs. Therefore, the practically possible upper limit is expected to be 2,400, considering some increase or decrease.
Considering the economic efficiency (cost-effectiveness) of the current construction costs, it seems appropriate to set the realistic number of pigs to be accommodated in the piggery of this invention to 100 to 500, but if the problem of construction costs is overcome, The upper limit of the number of pigs accommodated in the piggery of the present invention is 2400, and the range of the number of accommodated pigs can be 30 to 2400.

The technical idea of the pigsty or its WtoF unit, which forms the basis of this invention, can also be applied to the breeding of animals and plants other than pigs. It can be applied to breeding, cultivation of plants and seaweeds, and more specifically, it corresponds to three rooms of the WtoF unit of the present invention: the first WtoF room, the alternating fattening room, and the second WtoF room. Any space such as an aquarium, a cage, a site, a water area, etc. can be installed outdoors, or can be installed indoors. can be applied.
In the following, the structure will be described in detail together with the embodiments representing the present invention shown in the drawings.

The drawings show several representative examples embodying the technical idea of the pigsty of the present invention and the pig farming method using the same.

FIG. 2 is a plan view showing a conventional large-scale farm to which the pigsty of the present invention is added. 1 is a plan view showing a medium- or small-scale farm in which the pigsty of the present invention is installed; FIG. 1 is a flow chart showing a pig farming method using the piggery of the present invention. 1 is a flow chart showing more specifically a pig farming method using the piggery of the present invention.

In the example shown in FIGS. 1 and 2, a first WtoF room 4 having a floor area for housing a certain number of previously weaned piglets is provided, and first movable walls 40, 40 that can be opened and closed with the first WtoF room 4 are provided. When the first movable walls 40, 40 are opened and communicated, the floor area combined with the first WtoF room 4 is the floor area for housing a certain number of pre-fattening pig herds. A fattening room 5 is provided, and the alternating fattening room 5 is provided with a second WtoF room 6 having a floor space for housing the same number of subsequent weaned piglets as the preceding weaned piglet herd. and the second WtoF room 6 are adjacent to each other via the second movable walls 60, 60 so that they can be opened and closed, and the three rooms of the first WtoF room 4, the alternating fattening room 5 and the second WtoF room 6 constitute one WtoF unit 3 and at least one of the WtoF units 3 is installed indoors.

As can be clearly understood from these figures, the pigsty 2 of the present invention includes one WtoF unit in which an alternate fattening room 5 is sandwiched between a first WtoF room 4 and a second WtoF room 6. 3 is installed, said WtoF unit 3 having a first WtoF room 4, first movable walls 40, 40, alternating fattening room 5, second WtoF room 6 and second movable walls 60, 60, said first WtoF room 4 has a floor area of 0.30 to 0.72 m ² /head to accommodate a fixed number of 30 to 2400 pre-weaned piglets, more specifically, for example, 360 pigs. of 0.56 m ² /pig, ie 200 m ² /360 piglets, to house a pre-weaned piglet herd. If the floor area of the first WtoF room 4 (second WtoF room 6) is less than 0.30 m ² /head, weaned piglets cannot be raised comfortably up to 45 to 60 kg/head, and if it exceeds 0.72m ² /head. , the construction cost of the livestock barn 2 will rise.

The alternating fattening rooms 5 are arranged adjacent to each other via a first partition wall 41 which is sealed from the ceiling to the floor, and at both ends of the first partition wall 41 in the horizontal direction, there is a so-called barrier-free shape with no step on the floor surface. The entrances DW, DW are opened, and the respective entrances DW, DW are fitted with first movable walls 40, 40 that can be hermetically closed so as to ensure airtightness, and more specifically, the entrances DW. On the other hand, the first movable wall 40 having a flat plate shape with a larger area has a sealing material made of elastic resin around the entire circumference, is installed in an airtight manner, and is attached so that it can be removed and opened. Alternatively, the first movable wall 40 having a flat plate shape substantially matching the doorway DW is fitted on the upper and left and right outer peripheral edges thereof to the upper and left and right opening edges of the doorway DW excluding the floor surface. The first movable door has a substantially convex cross section when horizontally cut with a step, is provided with an elastic resin sealing material around the entire periphery, and has a hinge at one end in the horizontal direction. The wall 40 is either air-tightly closed and/or openably mounted and provided with a locking mechanism that can be tacked closed.
Further, the floor surface of the entrances DW, DW may be provided with a step of about 7 to 8 cm. It is possible to have a structure in which the floor surface of is closed in a fitted manner.

The alternating fattening room 5 has a total floor area of 0.7 to 1.2 ^m 2 , which accommodates the same number of pre-fattening pigs as the pre-weaned piglet herd with a certain number of 30 to 2400 pigs. / head, more specifically, for example, 1.00 m ² / head to accommodate a pre-fattening pig herd of 360 heads, that is, the area is set to 360 m ² /360 heads , In this case, the single floor area of the alternating fattening room 5 is the floor area obtained by subtracting the first WtoF room 4 from the floor area of the first WtoF room 4 + alternating fattening room 5, so the floor area of the alternating fattening room 5 is Floor area of 1WtoF room 4 + alternating fattening room 5 - floor area of 1st WtoF room 4 is 160 m ² . If the floor area of the first WtoF room 4 (second WtoF room 6) plus the alternating fattening room 5 is less than 0.7 m ² /head, the area where fattening pigs weighing 110 kg/head or more can comfortably live. However, if it exceeds 1.2 m ² /head, there is a drawback that the construction cost of the pigsty 2 becomes too large.
[Number 1]
360m ² -200m ² =160m ²

In addition, the second WtoF room 6 sandwiches the alternating fattening room 5, is opposite to the first WtoF room 4, and is symmetrical (laterally symmetrical) with respect to the first partition 41 with the indoor space of the alternating fattening room 5 interposed therebetween. ) are arranged adjacent to each other via a second partition wall 61 that is opposed to each other in a shape, and the second partition wall 61 is sealed from the ceiling to the floor, and has no step on the floor surface at both ends in the horizontal direction, So-called barrier-free doorways DW, DW are opened, and second movable walls 60, 60 that can be hermetically closed are attached to each of the doorways DW, DW so as to ensure airtightness. A second movable wall 60 having a flat plate shape with a larger area than the doorway DW has a sealing material made of elastic resin around the entire circumference, is installed in an airtight manner, and can be removed and opened. A second movable wall 60 that is attached or has a flat plate shape that substantially matches the doorway DW is provided on the upper and left and right outer peripheral edges of the upper and left and right opening edges of the doorway DW excluding the floor surface of the doorway DW. The cross section when horizontally cut has a step that fits into the door, and a sealing material made of elastic resin is provided around the entire periphery, and the door has a hinge at one end in the horizontal direction. The second movable wall 60 is either closed or opened airtightly.
Then, the second WtoF room 6 has the same floor area as the first WtoF room 4, and has a floor area of 0.30 to 0.72 m ² /pig that accommodates a constant number of 30 to 2400 subsequent weaned piglets. More specifically, it was set to an area of 0.56 m ² /pig to accommodate a subsequent weaned piglet herd of 360 piglets, i.e. 200 m ² /360 piglets. It's becoming

(Action and effect of Example 1)
In the pig farming method using the pigsty 2 of the present invention configured as described above, as shown in FIGS. , After washing and disinfecting the alternating fattening room 5 and the second WtoF room 6, the first movable walls 40 and 40 and the second movable walls 60 and 60 are hermetically closed (a), the first WtoF room 4 and the alternating fattening room 5 and second WtoF room 6 each as a separate room, and in said first WtoF room 4, 360 preweaners weighing 3 to 8 kg/head (or 4 to 15 kg/head), more specifically 6 kg/head. The pig herd is housed (b) and piglet rearing of the pre-weaned piglet herd is initiated (c).

11 to 14 weeks after the pre-weaned piglet herd has started piglet rearing, 360 pigs of 3 to 8 kg/pig (or 4 to 15 kg/pig), more specifically is adapted to house a subsequent weaned piglet herd of 6 kg/head (d), begins piglet rearing of the subsequent weaned piglet herd (e), and the preceding weaned piglet herd begins piglet rearing. 11 to 14 weeks later, when the pre-fattening pig herd weighs 45 to 60 kg/head (f), the first movable walls 40, 40 are opened, and the pre-fattening pig herd passes through the entrances DW, DW to the first WtoF. The room 4 and the alternating fattening room 5 are allowed to come and go freely (g), and meat pig fattening of the preceding fattening herd is started (h).
In other words, a weaned piglet herd needs 11 to 14 weeks from the start of piglet rearing to become a pre-fattening pig herd weighing 45 to 60 kg/head, and the entire fattening period (22 to 28 weeks) is required. In the second half of the week, the weight of the piglets naturally reaches 45 to 60 kg/head (f), and it can be said that it is desirable to open the first movable walls 40, 40 at this time (g).

After starting (h) fattening of the preceding fattening pig group, the weight of 110 kg / head or more, more specifically, for example, 110 to 130 kg / head is sequentially shipped from the preceding fattening pigs. By the time 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) have passed (k), the first WtoF room 4 and the alternating fattening room 5 will be completed (k). After cleaning and disinfecting (m), the first movable walls 40, 40 are hermetically closed (n), and 360 animals of 3 to 8 kg/head (or 4 to 15 kg/head), or more, are placed in the first WtoF room 4. Specifically, a new pre-weaned piglet herd of 6 kg/head is housed (p), and piglet rearing of the new pre-weaned piglet herd is started (q).
In fattened pig herds, the evaluation of meat quality is lowered when the body weight is less than 110 kg/head, and the evaluation of meat quality is not improved when the body weight exceeds 130 kg/head.

When 11 to 14 weeks have passed since the piglet rearing of the subsequent weaned piglet herd started and the subsequent fattening piglet herd weighed 45 to 60 kg/head (r), the second movable walls 60, 60 is opened, and the second WtoF room 6 and the alternate fattening room 5 are connected to form one fattening room (s) so that the entrances DW and DW can be freely passed, and the meat pig fattening of the subsequent fattening pig herd is performed. is started (t), and the subsequent fattening pigs that have reached a weight of 110 kg / head or more, more specifically, for example, 110 to 130 kg / head after the start of meat pig fattening of the subsequent fattening pig group are shipped sequentially. By the time 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) have finally passed, the shipment of all the pigs of the subsequent fattening herd is completed (v).

After that, the second WtoF room 6 and the alternating fattening room 5 were cleaned and disinfected (w), and the second movable walls 60, 60 were sealed and closed (x). housing (y) a new subsequent weaned piglet herd of between 8 kg/head (or 4 to 15 kg/head), more particularly 6 kg/head, and raising the piglets of said new subsequent weaned piglet herd; After going through the step of starting (z), again, the new pre-weaned piglet herd, 11 to 14 weeks after the start of piglet rearing, and a pre-fattening pig herd weighing 45 to 60 kg/head. From stage (f) onwards, the same process is repeated indefinitely, alternating every 11 to 14 weeks every 11 to 14 weeks for all piglets in the preceding weaned piglet herd and all piglets in the subsequent weaned piglet herd. 11 to 14 weeks after the fattening of meat pigs is started, all the pigs in the preceding fattening herd and all the pigs in the subsequent fattening herd are alternately shipped.

According to the pig farming method using the piggery 2 of the present invention as described above, a herd of 360 weaned piglets is produced by the conventional Vienna-to-finish (WtoF) and all-in-all-out (AI/AO) piggeries. When fattening to a fattening pig herd, for example, 324 m ² /360 pigs (0.9 m ² / head) are required. For example, it can be kept to 243 m ² /360 pigs (0.68 m ² / pig), and the floor space can be used more efficiently, so the site can be secured and the construction and equipment costs of the piggery 2 can be greatly reduced. .

In the case shown in FIG. 3, one WtoF unit 3 is arranged in the pigsty 2, and the first WtoF room 4, the alternating fattening room 5 and the second WtoF room 6 are connected in the longitudinal direction of the WtoF unit 3.

(Action and effect of Example 2)
In the pig farming method using the pigsty 2 of the present invention, as shown in FIGS. Hermetically closed (a), the first WtoF room 4, the alternating fattening room 5 and the second WtoF room 6 are each independent rooms, and the first WtoF room 4 contains, for example, 360 pigs of 3 to 8 kg/head (or 4 to 4 kg). 15 kg/head), more specifically 6 kg/head, is accommodated (b), and piglet rearing of said pre-weaned piglet herd is started (c).

11 to 14 weeks after the pre-weaned piglet herd has started piglet rearing, the second WtoF room 6 is provided with, for example, 360 pigs of 3 to 8 kg/pig (or 4 to 15 kg/pig), more specifically Specifically, a subsequent weaned piglet herd of 6 kg/head is housed (d), piglet rearing of the subsequent weaned piglet herd is started (e), and the preceding weaned piglet herd begins piglet rearing. After 11 to 14 weeks, when the preceding fattening pig herd weighed 45 to 60 kg/head (f), the opening and closing fences 52, 52 of the variable shipping pig pen 53 for the second WtoF room 6 were opened, and the first Open all the opening/closing fences GF, GF, . and the first movable wall 40 between the first WtoF room 4 and the meat pig fattening piggery 57, and between the first WtoF room 4 and the alternating fattening room 5 are allowed to move freely (g), and meat pig fattening of the preceding fattening herd is started (h).

When the pig fattening of the preceding fattening pig herd is started (h), the feeders/waterers FE, FE of the first WtoF room 4 move freely between the first WtoF room 4 and the alternating fattening room 5. , …… eating and drinking, fattening progresses, and when the weight of the preceding fattening pig approaches 110 kg / pig, the guide fence 58 is set at the entrance of the automatic weight measurement / sorting device 56 and the entrance of the first WtoF room 4 Installed between the opening/closing fence 52 of the side partition fence 51 facing the variable shipping pig bunch 54, and closing all the opening/closing fences GF, GF, ... of the variable shipping pig bunch 54 for the first WtoF room 4, Open and close fences GF, GF, . The pigs are enclosed in a shipping pigsty so that they cannot pass through the variable shipping pigsty 53 for the second WtoF room 6, and the automatic weighing/sorting device 56 is activated to continue fattening (h).

While eating and drinking with the feeders/waterers FE, FE, . . . While moving between the piggeries 57, it crosses the entrance DW and passes through the central corridor 50, is guided by the guide fence 58, and enters the entrance of the automatic weighing/sorting device 56. At this time, the weight is measured. When the unit automatically weighs and detects that the weight reaches 110 kg/pig or more, more specifically 110 to 130 kg/pig, the automatic sorting unit sends variable shipments for the first WtoF room 4. The automatic opening/closing delivery gate leading to the pig bund 54 is opened, the pre-fattening pigs themselves move to the variable shipping pig bund 54 for the first WtoF room 4, and the automatic opening/closing delivery gate is closed after the pre-fattening pigs pass through, When the breeder sequentially ships the preceding fattening pigs gathered in the variable shipping pig bund 54 for the first WtoF room 4 through the opening and closing fences (shipping routes) 52, 52, and the weight has not yet reached 110 kg/head or more In the second WtoF room 6, the automatic open/close delivery gate leading to the pig fattening piggery 57 containing the variable shipping piggery 53 for the second WtoF room 6 is opened, and the pre-fattening pigs themselves feed the meat containing the variable shipping piggery 53 for the second WtoF room 6. The thirsty and hungry pre-fattening pigs move to the pig tassels 57 for pig fattening and move themselves to the first WtoF room 4, where the one-way fence (one-way/ Through gates OW, OW, . . . , go to feeders/waterers FE, FE, . Each continues fattening while maintaining a state of self-repeating about 4 times/day on average (j), 11 to 14 weeks after the start of meat pig fattening of the preceding fattening pig group (start of piglet rearing From 22 to 28 weeks), the weight of 110 kg / head or more, more specifically, all the preceding fattening pigs that reached 110 to 130 kg / head in order from the weight of 110 kg / head or more, more Specifically, the shipment reaches 110 to 130 kg/head (k).

Even at the time (k) when shipping is completed in this way, fattened pigs with retarded growth may rarely appear. It is efficient in terms of work to ship the pigs without worrying about them, but there is a drawback that the market value will be lower than usual. It is possible to set up a remaining piggery (which may also serve as a sick piggery to accommodate sick pigs) and move it there for extended breeding. AO), some of which are exceptionally continuously reared, and with the exception of pre-fattening pigs that have not reached a shipping weight of 110 kg/head or more, other fattening of another WtoF unit 3 A herd of pigs (for example, either the first WtoF room 4 and alternating fattening room 5 of another WtoF unit 3 where space has become available due to progress in shipping, or the second WtoF room 6 and alternating fattening room 5, etc. Only when pigs of similar age just before shipping are mixed together, there is no disease problem, and fights do not occur because they have similar physiques.) It is possible to join and continue fattening. , In this case, it is no longer all-in-all-out (AI/AO), but if some pre-fattening pigs close to shipment are mixed with the subsequent fattening pig herd in this way, pathogens can be transferred and fights can occur. This breeding method is effective for shipping higher quality pigs because there is no problem such as the occurrence of If it reaches 110 kg/head or more, it is possible to deal with subsequent fattening pigs that are exceptionally retarded in the same way and ship them after raising them so that fattening will continue until they reach 110 kg/head or more. .

As described above, in the case of mixing the remaining pigs in another room at the stage of completing the shipment (k, v), more specifically, the remaining pigs are 1 to 2 production lots younger. It is better to move to a room, and one lot is usually one week, so it will be moved to a room for young pigs for 1 to 2 weeks. Since it will be 4-5 weeks, it will be moved to the room for the next production lot. , and conversely, from the second WtoF room 6 and alternating fattening room 5 in the same WtoF unit 3 to the first WtoF room 4 and alternating fattening room 5.

At this time, the weight measurement section of the automatic weight measurement and sorting device 56 automatically measures the weight, and the weight reaches 110 kg/head or more, more specifically 110 to 130 kg/head. When this is detected, the automatic sorting unit opens an automatic open/close delivery gate leading to the variable shipping pig bund 54 for the first WtoF room 4, and the pre-fattening pigs themselves move to the variable shipping pig bund 54 for the first WtoF room 4. When the preceding fattening pig finishes passing through, the automatic opening and closing delivery gate is closed, and the preceding fattening pigs collected in the variable shipping pig bunch 54 for the first WtoF room 4 are transferred to the first WtoF room. 4 while eating the feed from the feeder FD installed in the variable shipping piggery 54, and is led out of the piggery 2 through the opening and closing fences (shipping routes) 52, 52 and the central corridor 50 opened by the breeder's hands. It will be shipped sequentially.

In addition, as a result of entering the automatic weight measurement/selection device 56 from the entrance of the automatic weight measurement/selection device 56 facing the pig shed 57 for fattening and the weight measurement unit automatically measuring the weight, When the weight does not reach 110 kg/head or more, the automatic sorting unit opens the automatic open/close delivery gate leading to the other (second WtoF room 6) variable shipping pig pen 53 and precedes the same variable shipping pig pen 53. The fattening pigs themselves move, and when the preceding fattening pig has passed through, the automatic open/close delivery gate is closed, and the feeders FD, FD, . . . The thirsty preceding fattening pigs pass through the entrance DW near the central corridor 50, move to the feeding chamber 42 again, pass through the one-way gates OW, OW, . After that, he drank water from the water supply FE to quench his thirst, spent time in the auxiliary living quarters AR, living quarters 43, and pig quarters 57 for fattening pigs. Since each pre-fattening pig repeats the action of entering the sorting device 56 and undergoing weight measurement and shipping sorting at an average frequency of four times a day, fattening is continued while maintaining such an auto-sorting state ( j) Body weight of 110 kg/head or more, more specifically, within 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) after the start of meat pig fattening of the preceding fattening pig herd. All the pre-fattened pigs reach 110 kg/head or more, more specifically, 110-130 kg/head in order from the pre-fattened pigs that reach 110 to 130 kg/head, and the shipment is completed (k).

After that, the first WtoF room 4 and the alternating fattening room 5 are cleaned and disinfected (m), and the first movable walls 40, 40 are hermetically closed (n). GF, GF, . . . (and each one-way gate OW, OW, . ) More specifically, (p) accommodates a new pre-weaned piglet herd of 6 kg/head, and is designed to be blended according to the growth stage (body weight) in feeders FD, FD, ... equipped with an automatic feeding function. feed for piglets, supply drinking water to the waterer FE, heat the auxiliary living cell AR in winter to secure an environment suitable for breeding piglets, and create a new pre-weaned piglet herd. When piglet rearing is started (q), 11 to 14 weeks have passed since the start of piglet rearing of the subsequent weaned piglet herd, and the subsequent fattening pig herd weighs 45 to 60 kg/head (r ), the heating of the auxiliary living room AR in winter is stopped, all the second movable walls 60, 60 are opened (s), and the subsequent fattening pigs pass through the doorway DW, DW to the second WtoF room 6 and alternating fattening The entire area of the room 5 is used as a meat pig fattening room so that the pigs can freely walk around. In addition, each variable shipping pig bunch 53, 54 is also opened and each feeder FD, FD equipped with an automatic feeding function is fed according to the growth stage (body weight). The designed fattening feed is supplied and meat pig fattening of the subsequent fattening herd is started (t).

When the pig fattening of the subsequent fattening pig group is started, each subsequent fattening pig freely walks around the entire area of the second WtoF room 6 and the alternate fattening room 5, and feeders FD, FD, ... and waterers. After eating, drinking, and resting around FE, FE, and growing, and when the weight is about to reach 110 kg/head, all the opening/closing fences 52, 52, . . . At the same time, the opening/closing fences GF, GF of the variable shipping piggery 53 for the second WtoF room 6 are closed, and the variable shipping piggery 53 for the second WtoF room 6 is opened for the second WtoF room 6 and the first WtoF room 4. The pigs are separated from the pigs' bunch 54 and pigs' pigs' bunch 57 for fattening pigs, enclosed as a shipping pig's bunch 53, and the opening/closing fences GF, GF of the variable shipping pig's bunch 54 for the first WtoF room 4 are closed, and the first WtoF room 4 is closed. From the variable shipping piggery 54 for use, it is possible to move to the feeding pen 62 of the second WtoF room 6 only through the entrance DW near the middle corridor 50, and the opening and closing fences at both ends of the auxiliary partition fence AF in the second WtoF room 6. GF, GF are closed, and the one-way gates OW, OW, . to continue the meat pig fattening of the subsequent fattening pig herd.

When free movement is regulated by each one-way gate OW, OW, . After eating and getting thirsty, they pass through the one-way gates OW, OW, . After drinking the water from the vessels FE, FE, . The pigs look for the feeders FD, FD, . At this time, the weight measurement unit of the automatic weight measurement and sorting device 56 automatically measures the weight, and the weight reaches 110 kg/head or more, more specifically 110 to 130 kg/head. When this is detected, the automatic sorting unit opens an automatic open/close delivery gate leading to the variable shipping pig bunch 53 for the second WtoF room 6, and the subsequent fattening pigs themselves move to the variable shipping pig bunch 53 for the second WtoF room 6. When the subsequent fattening pig has passed through, the automatic open/close delivery gate is closed, and the subsequent fattening pigs collected in the variable shipping pig bunch 53 for the second WtoF room 6 are sent to the second WtoF room 6. While eating the feed from the feeder FD installed in the variable shipping piggery 53, the piggery is guided out of the piggery 2 through the opening and closing fences (shipping routes) 52, 52 and the central corridor 50 opened by the breeder, They will be shipped sequentially.

In addition, as a result of entering the automatic weight measurement/selection device 56 from the entrance of the automatic weight measurement/selection device 56 facing the pig shed 57 for fattening and the weight measurement unit automatically measuring the weight, When the weight does not reach 110 kg/head or more, the automatic sorting section opens the automatic open/close delivery gate leading to the other (first WtoF room 4) variable shipping pig pen 54, and the same variable shipping pig pen 54 follows. When the fattening pig itself moves and the subsequent fattening pig finishes passing, the automatic open/close delivery gate is closed, and the feed is fed by the feeders FD, FD, . . . The thirsty subsequent fattening pigs pass through the entrance DW near the central corridor 50, move to the feeding chamber 62 again, pass through the one-way gates OW, OW, . After that, he drank water from the water supply FE to quench his thirst, spent time in the auxiliary living quarters AR, living quarters 63, and pig quarters 57 for fattening pigs. Since each succeeding fattening pig repeats itself four times a day on average by entering the sorting device 56 and undergoing weight measurement and shipment sorting, fattening is continued while maintaining such an auto-sorting state ( u), within 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) after the start of meat pig fattening of the subsequent fattening pig herd, the body weight is 110 kg/head or more, more specifically All subsequent fattening pigs reach 110 kg/head or more, more specifically 110 to 130 kg/head in order from the subsequent fattening pigs reaching 110 to 130 kg/head (v).

The used second WtoF room 4 and alternating fattening room 5 are washed and disinfected (w), all the second movable walls 40, 40 are closed, and their entrances DW, DW are sealed ( x), each of the opening/closing fences GF, GF, . Feeder FD with automatic feeding function, with housing a new subsequent weaned piglet herd of 360 3-8 kg/head (or 4-15 kg/head), more specifically 6 kg/head (y). , FD, and so on are supplied with feed for piglets formulated according to the growth stage (weight), drinking water is supplied to the waterer FE, and in winter, the auxiliary living cell AR is heated to raise piglets. (z), and after that, the new preceding weaned piglet herd starts piglet rearing again. After 11 to 14 weeks, when a pre-fattening pig herd weighing 45 to 60 kg/head is obtained, the same process is permanently repeated from the stage (f).

Then, as shown in FIG. 5, when a plurality of, for example, two WtoF units 3, 3 are installed in one piggery 2 with an airtightly closed unit isolation wall 30 interposed therebetween, each WtoF Units 3 and 3 are managed in the same way as described above, enabling pig farming that efficiently implements Vienna to Finish (WtoF), All-in-All-out (AI/AO), and Auto Sorting. .

The example shown in FIG. 6 is a new large-scale farm 1 in which a piggery 2 of the present invention is installed. The pigsties 2, 2, . 11, a feces processing facility 14 and a urine processing facility 15 for processing excrements discharged from the farrowing barn 12 and the respective piggeries 2, 2, .

In the example shown in FIG. 7, a piggery 2 of the present invention is added to an existing large or medium-sized farm 1, and includes a quarantine pen 10, a breeding piggery 11, a delivery pen 12, a weaning pen 16, 16. Fattening sheds 17, 17, . A plurality of pigsties 2, 2 having a structure that is similar to the structure shown in FIG.

The example shown in FIG. 8 is a new medium- or small-scale farm 1 in which the piggery 2 of the present invention is installed. A plurality of pigsties 2, 2, . A facility 14 and a urine treatment facility 15 are installed respectively.

(Action and effect of Example 4)
According to the new large-scale farm 1 shown in FIG. 6, the farm 1 where the pigsty 2 of the present invention is installed is a farm 1 with a scale of 1,000 or more sows, and one week's worth of weaned piglets. When all-in/all-out (AI/AO) is performed as one group, 11 to 14 pigsties 2 of the present invention are required, depending on the shipping date, and WtoF of one pigsty 2 of the present invention. Unit 3 will have two groups of 11 to 14-week-old piglets, and if the owner is comfortable building a large piggery 2, one group will be weaned piglets for two weeks. 6 or 7 pigsties 2 of the invention are also possible. Similarly, in a farm 1 with a scale of 500 to 1,500 sows, if two weeks' worth of weaned piglets are put together into one group, the construction cost will be reduced, and the pigsty 2 of the present invention can be applied. It is also effective to separate the sow herd and the piglet herd into a two-site system or a multiple-site system.

In addition, according to the existing large-scale or medium-scale farm 1 shown in FIG. , the pigsty 2 of the present invention has been expanded, and until now, all the piglets transferred from the farrowing barn 12 were housed in the existing weaning barns 16, 16, but the pigsty 2, 2 of the present invention Since the number of sows is increasing with the expansion, the weaning houses 16, 16 are full before the piglets transferred from the farrowing house 12 reach the age of moving to the fattening houses 17, 17, . . . Therefore, the weaned piglets that could not be housed in the weaning houses 16, 16 are housed in the pigsties 2, 2 of the present invention.

When the capacity of the piggeries 2, 2 of the present invention is full, the piglets are moved to the fattening barns 17, 17, . . . Pigs can be accommodated, and the existing weaning houses 16, 16 and the pig houses 2, 2 of the present invention can be used alternately. The piggeries 2, 2 were added so as to rotate once, and the weaned piglets housed in the existing weaning pens 16, 16 were transferred to the existing weaning pens 16, 16 and the existing fattening pens 17, 17. , ... and housed in the piggeries 2, 2 of the present invention can be managed by continuing to raise them in the piggeries 2, 2 of the present invention until shipment, In other words, the piggeries 2, 2 of the present invention are treated as separate farms from the existing weaning barns 16, 16 and fattening barns 17, 17, . Therefore, only the piggeries 2 and 2 of this invention can be SEW (Segregated Early. The number of sows is increased 7/5 times, and in the case of housing for 6 weeks, the number is increased 6/5 times. Alternatively, if one piggery 2 of the present invention having either two WtoF units 3 or 3 shown in FIG. 5 is built, it can be operated smoothly. It is possible to form a pig flow with a cycle of receiving 1 to 2 weeks worth of piglets in the piggeries 2, 2 of the present invention for 4 to 5 weeks.

Then, according to the newly established medium- and small-scale farm 1 in which the pigsties 2, 2, 2 of the present invention are installed, as shown in FIG. A system (a system in which sows are divided into five groups and the breeding cycle is synchronized so that sows for four weeks are delivered in one week) is considered to be the best production method, and the five groups. In the system, it is sufficient if there is enough space to accommodate six groups after weaning, and the pigsty 2, 2, 2 of the present invention shown in any of FIGS. Either one of the 3 units 3, 3, 3 is required, and in the 7 group system, the pigsties 2, 2, ... of the present invention are 4, or the WtoF unit 3 of the present invention is 4 units 3, 3, 4. 3. Either one of the following is required, and in either case, adopting a two-site system will make it easier to suppress the outbreak of disease, and a farm with a scale of 150 to 300 sows 1 Then, by adopting the 7-group system and building two pigsties 2 of this invention with two WtoF units 3 shown in FIG. becomes higher.

(conclusion)
As described above, the pigsty and the pig farming method using the pigsty according to the present invention can widely achieve the intended purpose due to its novel configuration. Since costs, equipment costs, and running costs can also be suppressed, it can be made much more economical than a piggery having a conventional weaning barn and a fattening barn. Also, since it can greatly improve the work man-hours such as cleaning and disinfection, pig farms who want to realize more efficient pig farming by reducing the construction and maintenance costs of the piggery and the area occupied by the farm site. It is highly rated not only by the industry and the perishable food industry, which desires to provide higher quality and more economical meat, but also by ordinary households, who desire safer and more reliable pork at a lower price. It is expected that it will be widely used and spread.

A method for raising pigs using a piggery according to any one of claims 1 to 3 , characterized by a structure. The first movable wall and the second movable wall are hermetically closed, the first WtoF room, the alternating fattening room and the second WtoF room are each independent rooms, and the first WtoF room contains a certain number of preweaners of 3 to 15 kg/head. A pig herd was housed and piglet rearing was started, and the pre-weaned piglet herd became a pre-fattening pig herd weighing 45 to 60 kg/head 11 to 14 weeks after piglet rearing was started. When the first movable wall is opened to allow free passage, the pig fattening of the preceding fattening pig group is started, and at the same time as the fattening of the pigs of the preceding fattening pig group is started, a certain number of pigs are placed in the second WtoF room. A subsequent weaned piglet herd of 3 to 15 kg/head is housed and piglet rearing is started, and the preceding fattening pigs that have reached a weight of 110 kg/head or more are shipped in order, and fattening is started 11 to 12 hours later. By the time 14 weeks (22 to 28 weeks from the start of piglet rearing) have passed, all the heads of the preceding fattening pig herd have been shipped, and the first WtoF room and alternating fattening room are cleaned and disinfected, and the first After hermetically closing the movable wall, a new pre-weaned piglet herd of a certain number of 3 to 15 kg/head is housed in the first WtoF room to start raising the piglets, and the piglets of the subsequent weaned piglet herd are raised. When 11 to 14 weeks have passed since the start of the process and the subsequent fattening pig herd weighed 45 to 60 kg / head, the second movable wall was opened to allow free passage, and the second WtoF room and the alternating fattening room were separated. After connecting, the meat pig fattening of the subsequent fattening pig group is started as one fattening room, and the subsequent fattening pigs that have reached a weight of 110 kg / head or more are shipped in order, and the meat pig fattening is started. By the time 11 to 14 weeks (22 to 28 weeks from the start of piglet rearing) have passed, all the heads of the same subsequent fattening pig group have been shipped, and the second WtoF room and alternating fattening room are washed and disinfected. After hermetically closing the second movable wall, a new subsequent weaned piglet herd of a certain number of 3 to 15 kg/head was housed in the same second WtoF room, and piglet rearing was started, and the above series of steps was carried out permanently. 4. The method of raising pigs using a pigsty according to any one of claims 1 to 3 , characterized by a structure in which the steps are repeated. A step of closing all the second movable walls, opening all the first movable walls, connecting the first WtoF room and the alternating fattening room to form one fattening room, and fattening the pigs of the pre-fattening pig herd. In the meantime, until just before the preceding fattening pig herd reaches the shipping weight, the opening and closing fences of each part are kept open so that the entire area of the first WtoF room and the alternating fattening room can come and go, and the preceding fattening pig herd reaches the shipping weight. When reaching , the opening and closing fence of the variable shipping pig box for the 1st WtoF room is closed to make it a shipping pig box, the automatic weighing and sorting device is activated, and the one-way gate does not pass through the automatic weighing and sorting device. The traffic direction is regulated so that either the feeder or the waterer cannot be reached, and all the first movable walls are closed, all the second movable walls are opened, and the second WtoF room and alternating fattening room The whole area of the second WtoF room and the alternate fattening room until immediately before the subsequent fattening pig herd reaches the shipping weight during the process of fattening the pigs of the subsequent fattening pig herd. The opening and closing fences of each part are kept open so that they can come and go, and when the subsequent fattening pig herd reaches the shipping weight, the opening and closing fence of the variable shipping pig box for the second WtoF room is closed to make it a shipping pig box. In addition to activating the weighing and sorting device, the one-way gate is regulated so that either the feeder or the waterer cannot be reached without passing through the automatic weighing and sorting device, and the fattening pigs are hungry. Utilizing movement accompanied by physiological phenomena such as feeling and thirst, pigs were guided to pass through the automatic weighing and sorting device multiple times a day, and the fattened pigs that reached the shipping weight were designated as the shipping pig bunch. 7. The pig farming method using a piggery according to claim 6, wherein pigs are automatically guided and sorted to a variable shipping piggery.
