Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a poultry house and a poultry raising method using the same.
[0002]
[Prior art]
Poultry raising methods can be broadly divided into two categories: "cage-keeping" and "flat-house".
The origin of the cage is English cage (bird cage), and most of the current poultry farms adopt this method. In this method, tens of thousands of chickens are kept one by one in a cage installed in a poultry house, and the cage is equipped with a device that automatically transports feed (feed), and eggs that have been laid Is a method suitable for mass production, for example, there is a conveyor with a conveyor for automatically collecting wastewater.
[0003]
On the other hand, the “flat house” method is a method in which chickens are kept in a poultry house without moving in cages, and the chickens lay eggs in nesting boxes for laying eggs.
The flat feed method generally produces better-quality eggs than cage feed, and has attracted attention in recent years due to the gourmet boom and healthy diet. This method allows the eggs to be quarantined more quickly than in cages, so that the eggs can be collected manually before they become dirty or scratched.
The qualities required for edible chicken eggs include, of course, the taste, decay resistance, low cholesterol, and low allergens.
Of the above two methods, the flat type is raised in a more natural manner than the cage type, and thus is superior in several points in terms of the taste of eggs and the like.
[0004]
[Problems to be solved by the invention]
However, in the flat-breeding system, chickens can move freely, and extra-nest eggs that lay eggs outside of the egg-nesting nest box are generated. Eggs outside the nest are apt to get germs and need to be washed to remove dirt.
For this reason, the administrator needs to inspect the inside of the poultry house other than the nest box and collect eggs outside the nest, but there is a problem that it takes time to collect the eggs because the chickens are in the way. Also, there is a problem that a great stress is generated in the chicken, and the stress causes a decrease in the number of eggs laid in the nesting box for laying eggs and an increase in eggs outside the nest.
A similar problem occurs when cleaning the inside of a poultry house. If the floor is not cleaned, coccidiosis and the like may occur.
[0005]
The problem to be solved by the present invention is to provide a poultry house capable of producing high-quality eggs by improving both the breeding environment of chickens and the working environment of workers, and a chicken raising method using the same.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the poultry house of the present invention includes a mesh wall provided around the perimeter of the soil, and an egg-laying nest box provided on a part of the mesh wall, and is capable of breeding a plurality of chickens. In a poultry house in which a plurality of breeding rooms are arranged side by side and the upper part is covered by a roof, the outside of each of the breeding rooms can enter and leave the breeding room through an openable door portion formed on the mesh wall. In each of the sports fields, the surroundings are surrounded by a mesh wall and the upper part is opened.
[0007]
In the present invention, during the daytime on a sunny day, the door is opened and the chickens are put out on the playground to exercise. When exercising in the playground, you are exposed to direct sunlight, so that the occurrence of various bacteria can be suppressed, and healthy chickens can be bred. On a rainy day, the door is closed and reared in the rearing room, so that the chickens do not get wet, and the chickens can move freely in the rearing room, thereby preventing lack of exercise.
Since a breeding room and a playground are provided in a pair, chickens can freely move to and from each breeding room and the playground. In addition, it does not replace chickens in other breeding rooms or playgrounds. As described above, chickens are bred with less stress, produce high-quality eggs in the nesting box for laying eggs, and have the effect of reducing eggs outside the nest.
[0008]
Also, when checking or cleaning the breeding room, the chickens can be put out into the playground, and when checking or cleaning the playground, the chickens can be put into the breeding room. Since the chicken can be moved to the breeding room or the playground, the operation can be performed quickly without disturbing the operation.
[0009]
Each breeding room may be provided with a perch whose vertical position can be adjusted.
Immediately after a chicken raised in a poultry house without a perch enters the poultry house with a perch, it cannot stop at the perch, so it cannot stop at the spawning nest box and eggs outside the nest can Will increase.
[0010]
If a perch with adjustable vertical position is placed below the breeding room, the chickens will stop immediately even after entering. In addition, when arranged on the upper side, other chickens can move under the perch, so that dust such as feathers and dirt causing odors do not accumulate, and cleaning is simplified.
In addition, by providing the perch, the chickens can be dispersed and the distance between individuals increases, so that stress is reduced.
[0011]
The breeding room and the playground may be arranged in a straight line, and the mesh wall between the playground and a playground adjacent to the playground may be provided with a door that can be opened and closed by a vehicle and that can be opened and closed.
When constructing a large poultry house, it takes a lot of time for workers with cleaning tools etc. to move inside on foot, but by providing a door through which vehicles can pass, the sports ground can be moved by vehicle, Work time is reduced.
[0012]
A large roof that covers the entirety of each breeding room on the roof, and has an upper end arranged on the playground side and is inclined, and is inclined in a direction opposite to the large roof, and a lower position of an upper end of the large roof. When the base end is arranged and a small roof is provided so as to protrude toward the playground side, the net-like wall on the playground side can be covered by a small roof arranged at a position lower than the large roof. It is prevented that rain falls. Further, since the hot air accumulated inside can be released from between the small roof and the large roof, ventilation can be performed efficiently.
[0013]
It is also possible to provide a roll-up curtain member that covers all the mesh walls on the playground side and all the mesh walls provided on the side opposite to this.
The breeding room is surrounded by a mesh wall, so it has good ventilation, but it can stress the chickens in strong winds. By providing the curtain member, the wind is blocked and the stress of the chickens in the poultry house is reduced.
[0014]
By using a roll-up type curtain member such as a roll curtain, all the net-like walls can be covered with one curtain member at a time, and the mechanism is simplified and the operation time can be reduced.
In addition, it is preferable to install a plate-like wall made of a tin or the like that blocks the wind and is a blindfold from the outside on both outer side surfaces of the poultry house where the curtain member is not provided.
[0015]
Each of the breeding rooms may be provided with a nozzle for ejecting mist-like water droplets.
When water drops are ejected from the nozzles at high temperatures in summer, the surrounding heat is removed when the water droplets evaporate, so that the temperature in the breeding room falls and the body temperature of the chicken returns to an appropriate value, so that sufficient food can be taken. Become.
[0016]
It is preferable to form a rice hull bed overlaid with rice hulls on the soil in the breeding room, and to make the egg-nesting nest box made of metal.
Chicken manure discharged by the chicken is captured by the air-containing rice hull bed and decomposed by aerobic bacteria living in the upper layer of the ground. Since the rice hull bed is provided, the surface temperature between soils is kept constant and contains air, so that aerobic bacteria inhabiting the upper layer of the ground are easily propagated. Aerobic bacteria break down poultry manure into carbon dioxide and water, so the air inside the poultry house is always kept clean and odorless.
In addition, it is known that when a nesting box for laying eggs is made of metal, the occurrence of various bacteria is suppressed as compared with a wooden nesting box, and the quality of eggs is improved by such a configuration.
[0017]
The poultry raising method using the poultry house of the present invention includes a plurality of breeding breeders capable of breeding a plurality of chickens, including a mesh wall provided around the soil, and a spawning nest box provided on a part of the mesh wall. In the poultry raising method using a poultry house in which the rooms are arranged side by side and the upper part is covered by a roof, a perch whose up and down position is adjustable is provided in each of the rearing rooms, and the height of the perch is adjusted by Gradually increase according to the height that can be gripped.
[0018]
The higher the position of the perch, the more convenient it is to work in the poultry house, but the lower the position of chickens that are not used to the perch, the easier it is to stop. For this reason, immediately after a chicken enters a poultry house, it is arranged in a low position, and is gradually changed to a high position as the chicken gets used to it. By adjusting the position of the perch in this way, the chickens can quickly learn to stop on the perch, and also quickly learn to stop and lay eggs in the nesting box for nesting. Can be.
[0019]
In addition, when the perch is arranged at a high position, chickens and workers can move below the perch, so that chicken dung does not stay and the operation can be performed quickly.
The height of the perch can be adjusted by, for example, attaching a lattice-like member to the rearing room so that the base end thereof is rotatable, and using a fixing means such as a rope to change the fixing position of the tip end.
[0020]
At the outside of each breeding room, there is provided an athletic field which can enter and exit the breeding room through an openable door portion formed on the mesh wall, is surrounded by a mesh wall and has an upper opening, and Preferably, the section is closed until the chicken is ready to lay eggs in the egg-laying nest box, and is opened after the eggs are ready to lay eggs to bring the chicken to the playground.
[0021]
If a chicken is placed on the playground before it can be laid in the nesting box, it may lay eggs on the playground. If there are eggs outside the nest in the playground, it takes time to collect, and since it is outdoors without a roof, dirt increases, and subsequent washing work also takes time, but chickens stop perching, In addition, since the eggs are laid in the playground after the eggs can be laid in the nesting box, the number of eggs outside the nest in the playground is reduced, and the collection time of the eggs is shortened.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
1 is a perspective view of the poultry house of the present invention, FIG. 2 is a plan sectional view of the poultry house, and FIG. 3 is a side sectional view of the poultry house.
[0023]
As shown in FIGS. 1 to 3, a poultry house 1 of the present invention includes a straight passage 2, a plurality of breeding rooms 3 linearly arranged adjacent to the passage 2, and a plurality of breeding rooms 3 adjacent to each breeding room 3. , A plurality of playgrounds 4 provided on the opposite side of the passage 2 and a roof 8 covering each breeding room 3.
[0024]
The breeding room 3 is provided with mesh walls 5 to 7 provided so as to surround the rectangular soil 2. The mesh walls 5 and 6 are provided on the passage 2 side and the playground 4 side, respectively, and the mesh walls 7 face the playground 4 side and are arranged on both left and right sides to face each other.
The reticulated walls 5 to 7 are made of plastic so that an enemy such as a dog cannot bite and cut, and a lower end portion of the mesh wall 5 to 7 is placed underground so that the dog does not dig into the ground and invade from below. It is installed buried about 50 cm.
In addition, at both ends in the longitudinal direction of the poultry house 1, there are provided galvanized side walls 24.
[0025]
The playground 4 is formed to have the same size as the breeding room 3, a mesh wall 12 is provided on a side facing the mesh wall 7 provided on the breeding room 3 side, and a mesh wall 13 is provided on both left and right sides facing the breeding room 3 side. Are arranged facing each other. The upper part of the playground 4 is open, and the chickens in the playground 4 can be directly exposed to sunlight.
[0026]
A spawning nest box 9 is provided on the mesh wall 5 on the side of the passage 2. The spawning nest box 9 is made of metal and has upper and lower openings. The eggs laid by the chickens are thrown in from the upper opening, and the eggs can be collected from the lower opening that opens to the passage 2 side without the worker entering the breeding room 3. Note that a door 25 is also provided on the mesh wall 5 on the side of the passage 2 so that an operator can enter and exit.
[0027]
A door 10 that can be opened and closed is formed on the mesh wall 6 on the side of the playground 4. The chicken can move between the breeding room 3 and the playground 4 via the door 10.
[0028]
A rice hull floor 11 in which rice hulls are spread to a thickness of 5 to 10 cm is formed on the soil of the breeding room 3. The chicken moves on the rice hull bed 11 and stirs the chicken manure excreted at the top together with the rice husk. Chicken manure is decomposed into water and carbon dioxide by the action of aerobic bacteria living in the upper part of the soil, so that the air in the breeding room is kept clean and the generation of odors is prevented.
[0029]
Further, in the breeding room 3, three vertically movable water dispensers 14 are provided. Since only a necessary amount of water is supplied from the top, no drainage is required, and the drainage ditch outside the poultry house 1 is not contaminated.
[0030]
At the upper part of the breeding room 3, a nozzle for ejecting mist-like water droplets is provided. The jetted water droplets evaporate and remove heat in the breeding room 3 to lower the temperature. The supply of water to the nozzle can be from the same source as the water supply 14. If the chicken's body temperature rises and there is a risk of heat death, drop the water droplets on the chicken's living surface, wet the chicken's body surface, and evaporate this water to directly lower the chicken's body temperature An emergency evacuation method is also possible.
In addition, a feeding gutter (not shown) is provided in the center of the breeding room 3 so that the chicken can ingest a required amount of food.
[0031]
On the side of the breeding room 3 on the playground 4 side, a perch 15 whose vertical position can be adjusted is provided. The perch 15 includes a plurality of horizontal bars 16 and two support bars 17 connecting both ends of each horizontal bar 16, and is formed in a wide ladder shape.
[0032]
The upper ends of the two support rods 17 are rotatably supported by beams on the net-like wall 6 on the playground 4 side. By attaching a string-like member (not shown) to the horizontal bar 16a arranged at the lowermost position and fixing the string-like member in a state of being pulled upward, the perch 15 can be arranged at an arbitrary height.
[0033]
The roof section 8 has a large roof 18 and a small roof 19.
The large roof 18 covers the whole breeding room 3 and the upper part of the passage 2, and is inclinedly arranged with its upper end arranged on the playground 4 side. A heat insulating material 20 is provided on the back side of the large roof 18 so that a temperature change in the breeding room 3 is reduced.
[0034]
The small roof 19 is inclined in the opposite direction to the large roof 18, and is disposed below the upper end of the large roof 18 so that the base end thereof overlaps when viewed from above, and the distal end is positioned below the playground 4 side. It is provided overhanging.
[0035]
The air in the breeding room 3 is warmed and rises, and is discharged outside through the gap between the small roof 19 and the large roof 18.
When it rains, the rainwater is discharged from the large roof 18 to the passage 2 side, and discharged from the small roof 19 to the playground 4. When it is raining and the wind is blowing, the passage 2 may be wet, but since the lower end of the large roof 18 covers the passage 2, the inside of the breeding room 3 is not wet. Further, since the small roof 19 is provided, it is possible to prevent rain from falling from the playground 4 side. Furthermore, the small roof 19 prevents direct sunlight from being applied to the breeding room 3 on a midsummer day, and prevents the temperature in the breeding room 3 from becoming too high and the growing condition of the chickens from being deteriorated.
[0036]
One roll-up curtain member 21 is fixed to the lower side of the small roof 19 outside each mesh wall 6 on the playground 4 side. One roll-up curtain member 22 is fixed to the lower side of the large roof 18 outside each mesh wall 5 on the side of the passage 2.
[0037]
The curtain members 21 and 22 can simultaneously cover the plurality of breeding rooms 3 and block the wind. Usually, the curtain members 21 and 22 are rolled up to improve ventilation, and the playground 4 side and the passage 2 side are opened. However, on windy days, the curtain members 21 and 22 are reduced to reduce the stress given to the chicken. Lower.
[0038]
The mesh wall 13 between the playground 4 and the playground 4 adjacent to the playground 4 is provided with a door 23 that can be opened and closed, through which a vehicle (not shown) can pass.
A work vehicle such as a truck can be moved to a position adjacent to a predetermined breeding room 3 by opening each door portion 23.
With this configuration, even when a large poultry house 1 is constructed, it is possible to quickly carry in materials for repair and the like and take out chicken dung and the like discharged from each breeding room 3.
[0039]
Each poultry house 1 is provided with a service room (not shown), and the service room is provided with a proportioner (chemical solution injector) and an electromagnetic valve for switching on and off water supply. When stress was applied to the chicken, a drug (lactic acid bacterium, sugar solution, etc.) for reducing the stress was administered at any time, and when there was a concern about freezing, the water tap was closed before the lights were turned off, and the chicken remained in the water supply 14. By having the chicken drink up the water, it is possible to prevent the water supply from being destroyed due to freezing.
[0040]
Next, a chicken raising method using the poultry house 1 will be described.
The chicken returned from the egg is raised in another place until it reaches a predetermined size, and then is carried into the poultry house 1.
Immediately after being brought in, the chicken cannot grip the perch 15 with its claws, and therefore cannot grip the edge of the egg-laying nest box 9.
Such chickens often lay eggs on the rice hull floor 11 and on the playground 4 until they become accustomed to the environment. In order to improve this at an early stage, the poultry raising method of the present invention provides a training period for laying eggs in the nesting box 9 for laying eggs.
[0041]
(Chicken training process)
After carrying the chickens, the door 10 provided between the breeding room 3 and the playground 4 is kept closed, so that the chickens do not go out to the playground 4 during the training period. .
[0042]
In an early stage of the training process, the perch 15 is arranged at the lowest position. In this state, the horizontal bar 16a provided at the bottom is arranged at a height that allows the chicken to climb up if the chicken jumps up a little. This can be gripped by putting a foot on the.
In addition, since the foot reaches the horizontal bar 16 in the upper stage from this state, the chicken can gradually move upward.
[0043]
After confirming that the chicken has stopped at the perch 15, the height of the perch 15 is fixed slightly higher. By repeating this and gradually raising the perch 15 to the height that the chicken can grip, the chicken can easily jump up and stop on the perch 15.
The perch 15 is finally set to a height at which other chickens and workers can pass below the perch 15.
[0044]
At the stage where the height of the perch 15 is increased, the chicken also stops at the edge of the egg-laying nest box 9. After the chicken stops at the edge of the egg nesting box 9 and can lay eggs, the door 10 between the chicken and the playground 4 is opened, and the chicken can be moved on the playground 4.
[0045]
Since the height of the perch 15 is gradually increased, compared to a chicken house in which the perch is fixed at a high position, the chicken can be stopped by the perch in a short period of time, and the nesting box 9 for laying eggs in a short period of time. Since eggs can be laid inside the nest, eggs outside the nest can be reduced and high-quality eggs can be stably collected.
Further, the door 10 is closed until the eggs can be laid in the nesting box 9 for laying eggs.
[0046]
【Example】
An analysis test was performed on eggs laid by chickens bred by the chicken raising method using the poultry house of the present invention. The test was requested to the Japan Food Research Laboratories.
The amount of cholesterol measured by gas chromatography was 368 mg / 100 g. This is a very low value compared to the cholesterol content of a commercially available egg of 630 mg / 100 g (Japanese Food Composition Table (Fourth Edition)). This difference in the amount of cholesterol is considered to be due to the large amount of exercise of the chicken bred by the poultry raising method using the poultry house of the present invention.
[0047]
【The invention's effect】
According to the present invention, the following effects can be obtained.
(1) Since the poultry house of the present invention is provided with a pair of breeding rooms and playgrounds, the density of the chickens in each breeding room and playground is constant, and the chickens can freely move to the environment desired by the chickens. Chicken is bred with less stress, and the breeding environment for chicken is improved.
Further, since stress is reduced, eggs outside the nest are reduced, and high-quality eggs can be produced.
Further, since the chicken can be moved to the breeding room or the playground, the operation can be performed quickly without disturbing the operation, and the working environment is improved.
(2) If a perch is provided in the breeding room that can be adjusted up and down, it can be remembered that even a chicken that has just entered the house will stop immediately, and the time it takes to lay eggs in the nesting box for eggs will be short. Become. In addition, when the perch is arranged on the upper side, other chickens can move below the perch, so that the odor-causing filth and the like do not stay, and the cleaning is simplified. Further, by providing perch, the chickens can be dispersed and the distance between individuals increases, thereby reducing stress.
(3) Also, the lower end of the perch is fixed to the upper part when cleaning after carrying out the spawning hens, but if this is hung directly below and parallel to the mesh wall, it will be a hindrance to the room. As cleaning efficiency is eliminated, cleaning efficiency is dramatically improved.
(4) When the doors that can be opened and closed by the vehicle are provided on the mesh wall between the playground and the adjacent playground, the playground can be moved by the vehicle, and the work time can be reduced.
(5) If a small roof is provided on the roof, the mesh wall on the sports ground side can be covered with a small roof arranged at a position lower than the large roof, so that rain is prevented from falling into the breeding room due to wind. Further, since the hot air accumulated inside can be released from between the small roof and the large roof, ventilation can be performed efficiently.
(6) If a roll-up curtain member is provided to cover all the mesh walls on the playground side and all the mesh walls provided on the opposite side, the wind is blocked, and the stress on the chickens in the poultry house is reduced. It can improve the quality of eggs.
(7) If the breeding room is provided with a nozzle for ejecting mist-like water droplets, the temperature of the breeding room will drop and the body temperature of the chicken will return to an appropriate value at the time of high temperature in summer, and the food will be sufficiently consumed. Therefore, a decrease in egg quality can be prevented.
(8) By forming a rice hull floor with rice husks spread over the soil in the breeding room and making the nesting box made of metal, the air inside the poultry house is always kept clean to improve the breeding environment and working environment, Quality can be improved.
(9) In the poultry raising method using the poultry house of the present invention, the height of the perch is gradually increased in accordance with the height that the chicken can grip, so that it is quickly learned that the chicken stops on the perch, and Since it is easy to learn to stop nesting and lay eggs, the number of eggs outside the nest is reduced and the operation can be easily performed. In addition, when the perch is arranged at a high position, chickens and workers can move under the perch, so that chicken dung does not stay and the breeding environment and the working environment are improved.
(10) The door that can enter and exit the playground and the breeding room is closed until the chickens can lay eggs in the nesting box, and opened after the eggs are laid, and the chickens are put out of the playground. Eggs outside the nest are reduced, and the collection time of eggs is reduced.
