In addition, when pigs are raised in a multi-storey building, the breeding density of a single square area is increased, and more severe requirements are provided for biological safety prevention and control. And the ammonia concentration in the plant house is high, and especially multi-storey building, the stink radiation range is wide, and the influence area is big, causes certain influence to surrounding villager residential environment. One important reason for the return of most of scattered households in recent years is the normalization of African swine fever. Therefore, biosafety is becoming increasingly important for swine systems.

The pig raising system of the application also makes a series of improvements on the aspects.

According to one embodiment of the present application, the pig raising area may be divided into: dirty areas, isolation areas, in-field safe areas, and clean areas. Wherein the dirty area is an area outside the culture system. The isolation zone may include areas such as transit piggery, staff dormitory, dining room, pig farm office, dining room, dirty treatment zone of excrement, staff isolation zone, dead pig treatment zone. The on-site safety area includes areas inside the production area, outside the building (where pigs are accommodated, which may also be referred to as a "pigsty"), production auxiliary facilities, facilities outside the building, and the like. The clean area can be the area such as building inside and airtight vestibule. The areas of the pig raising system are distinguished, and corresponding adjustment is carried out on different areas, so that the biological safety of the pig raising system can be effectively guaranteed.

Fig. 1 is a schematic overall layout of a pig raising system for a multi-storey building according to an embodiment of the application.

As shown in the figure, a plurality of buildings with a single function can be constructed in a clean area of a pig raising system 100 (hereinafter referred to as a "pig raising system") of a multi-storey building according to a plurality of main stages of pig raising. According to one embodiment, the pig raising system 100 may include at least 1 gestational shed 110, 1 farrowing shed 120, and 1 nursery 130 and one fattening house 140 connected to each other by a corridor 150, thereby achieving peer-to-peer transfer of pigs. According to one embodiment, the clean zone may also include a backup house 160. In some embodiments, the number of floors in a building may be, for example: 2, 3, 4 or more layers. According to another embodiment, it is also possible to place care and fattening in the same building but to distinguish between care and fattening fields.

In some embodiments, separate washing and disinfecting facilities and deodorizing facilities may be provided in each of the gestational shed, the birthing shed, the nursery and the fattening shed. Of course, independent decontamination or deodorization may be provided in only one or more of the plants as desired.

According to one embodiment, the isolation region may include: an isolation house 170, a pig house 180 and a fecal sewage treatment area 190. The functions and features of each zone will be described below in terms of the process of circulation of pigs.

According to one embodiment, the pig farming system 100 may include an isolation house 170, which may be used to introduce isolation of pigs. According to one embodiment, the isolation shed can be connected with other buildings without corridors, and the pigs are only transported by vehicles. For example, after the isolation is finished, the replacement sows are transferred from the pig-out platform on-site pig carrying cars at the outlet of the isolation shed 170 to the replacement shed 160 along the on-site roads for replacement breeding. This is for better isolation purposes. According to one embodiment, the number of isolation houses 170 and the number of layers can be a single layer, but can be adjusted as desired.

In some embodiments, 200 replacement pigs are externally introduced, aged about 4 months and weighing about 50 to 60 kg, into the isolation shed from an entrance at one side of the isolation shed 170, and observed and isolated in the isolation shed for 4 to 5 weeks, according to the size of the basal sows and the number of commercial pigs that are released each year.

According to one embodiment, the pig farming system 100 may also include a back-up house 160 that may be used to introduce the breeding view of pigs and the breeding view of back-up growing pigs. According to one embodiment, the backup houses may be connected to other buildings via an enclosed corridor 150.

In some embodiments, artificial insemination is performed at the second through third instar, typically at the second through third instar, after 4 weeks of post-house 160 large-size rearing, for a suitable 4 weeks of breeding in the check-out cage, for a month of age of about 7 to 8 months, and a weight of about 130 to 140 kg, and then delivered to the gestational house.

As will be appreciated by those skilled in the art, the present application is described in terms of whole-course feeding (i.e., self-breeding), and the present application may also be applied to other feeding regimes, such as: when only the fattening pig feeding (i.e., the feeding by purchasing piglets) is performed, only the nursing fattening house may be included.

According to one embodiment, the pig farming system 100 may include a gestational shed 110 for sow mating. The breeder determines that a sow successfully bred is driven to the gestational litter for gestational feeding, e.g., 16 weeks, via, e.g., the containment corridor 150.

According to one embodiment, the pig raising system 100 may comprise a farrowing house 120 for farrowing sows, wherein the sows to be farrowing are transferred from the internal walkway to the farrowing house for farrowing 2 to 3 days before the edd, and wherein the sows are weaned after the farrowing house 120 to 3 weeks. According to one embodiment, the bred weaned piglets can be transferred from the closed corridor to a replacement house for replacement breeding, the sows are transferred to the gestational house 110 for next mating after oestrus is given again, and the bred piglets can be transferred from the closed corridor to a nursing house and a fattening house for breeding.

In some embodiments, the breeding sows are selected and marked with ear defects before weaning according to appearance, parental production performance, defect-free other pigs in the same litter, and the like. The reserved weaned piglets and the rest weaned piglets are fed in groups and are all driven to a nursing house and a fattening house through a closed corridor for breeding. For example, after 11.5 weeks in a nursery house, pigs are 14.5 weeks old and transferred to a fattening house through an internal walkway. The pigs are transferred out after 11.5 weeks of breeding in a fattening house to 26 weeks of age. In some embodiments, it is also necessary to clean and disinfect the columns, equipment, etc. in the nursery and fattening houses. For example: the washing and the disinfection are respectively carried out in the nursery house and the fattening house for 0.5 week.

According to one embodiment, the pig farming system 100 may include a nursery house 130 and a fattening house 140 as spaces for growth and fattening of piglets. The volume of the pigs in the fattening stage is generally larger than that of the pigs in the nursing stage. Therefore, generally, the field of the fattening house is larger than the field of the nursing house. In addition, the conventional breeding method is to breed pigs in the breeding house for 8 weeks and the fattening house for 16 weeks, that is, the number of the fattening house columns is more than that of the breeding house, for example, the number of the fattening house columns is 2 times of that of the breeding house columns.

However, the present inventors have observed that pigs only leave the nursery often not have a volume that the nursery columns cannot accommodate. In order to improve the utilization efficiency of the building area and follow the law of pig breeding, the inventor adjusts the nursing and fattening weeks to be the same, for example, 12 weeks. Thus, the number of the columns in the nursery house and the number of the columns in the fattening house can be set to be the same, and the pigs are changed from the period of time when being used in the fattening house to the period of time when being used in the nursery house. Compared with the traditional pigsty, the building house arranged in such a way can reduce the total building area by 5 percent.

According to one embodiment, the pig farming system 100 may also include an exit pigsty 160, which may be used to store the transports of fattened pigs for sale, or to reject the transports. According to one embodiment, the fattening house may be connected with the pig house through a rotary staircase or a closed corridor, or may be transported through vehicle transport.

In some embodiments, the following conditions occur during the feeding process, such as a multiparous sow. Such as: the sow is not suitable for the intra-site gestational age structure, the sow has the existing service life, the body condition is poor, the litter yield is low, the number of non-pregnant days is too long, the sow is difficult to estrus again, the conception is difficult, the maternal performance is poor, the production score is low, and the like, and the sow needs to be eliminated. According to one embodiment, sows to be eliminated on each floor in the gestational facility 110 may be driven to the first floor by a spiral staircase, transferred from the on-site road to an out-pig facility by an on-site pig transport cart, and transferred to an external pig pulling cart by an out-pig platform.

In some embodiments, when dead pigs appear in each building, the dead pigs are transported from each building to a hydraulic elevator of the deodorization room, descend to the first floor and then are pulled to a harmless treatment workshop of the fecal sewage treatment area for uniform treatment.

In some embodiments, the corridor 150 may be a closed corridor, which is mainly used for transporting pigs between houses in clean areas in the same layer, thereby avoiding cross-layer infection and improving biological safety. Of course, the vestibule 150 may not be sealed, but may be provided that a same layer of swine transfer is possible.

In some embodiments, each building house in the pig-raising system 100 may further include a deodorization room, which may be used to deodorize and filter the gas in the building house, prevent odor radiation from affecting the surrounding environment or surrounding residents, and achieve independent ventilation, which is a consideration in terms of biosafety. In some embodiments, because the deodorization room does not contain pigs, the bearing grade of the deodorization room can be lower than that of other components in the building house, so that the building cost can be reduced and the surrounding environment can be greatly improved on the premise of meeting the requirement of the deodorization function. In some embodiments, a deodorization room is not necessarily arranged in each building, and the deodorization rooms can be arranged according to the mutual relation of buildings.

In some embodiments, the pig raising system 100 may further include a fecal sewage treatment area 190, which may be used to treat sewage, feces, etc. generated by the whole pig raising system, so as to avoid pollution to the surrounding environment, and to treat dead pigs harmlessly to prevent disease transmission.

In some embodiments, the number of layers of each building house is the same, so that the pigs in each building house in the same layer can be conveniently transported, the crossing among the layers of the building houses can be avoided, and the biological safety of the pigs in the building houses can be ensured. For example: when the sows to be delivered in the gestational house are transferred to the same-layer farrowing house for delivery before the estimated delivery period (for example, 2 to 3 days), the sows are transferred to the same-layer nursery and fattening house after the piglets in the farrowing house stay to weaning, and the sows return to the gestational house.

In some embodiments, the building foundation in pig farming system 100 may be formed as a pile foundation with a cap. Wherein, the main structure form can be a frame structure. In some embodiments, the building roof can adopt the steel construction to reduce the dead weight, practice thrift the cost, reduction of erection time. In some embodiments, the house roof insulation can be heat preservation and insulation by adopting glass wool and steel wire meshes. In some embodiments, the roofing glass wool has a fire retardant rating of class a1 and may be 75mm thick. In some embodiments, the P6 grade impervious concrete can be used as the floor concrete, and the impervious and waterproof capabilities of the concrete can be utilized, so that the construction of a flexible waterproof layer and a leveling protective layer can be eliminated, the construction process is reduced, and the construction cost is saved.

In some embodiments, the floor of the pig raising system 100 can be trowelled by concrete raw slurry and formed in one step, and no leveling layer or surface layer is needed, so that the construction procedures can be reduced. In some embodiments, the exterior wall insulation material of the pig raising system 100 can be polyphenyl granule insulation mortar, which not only meets the energy-saving requirement, but also has high strength, and can avoid common quality problems such as cracking, water seepage, falling and the like caused by using plastic plates, thereby improving the engineering quality, shortening the construction period and reducing the cost.

The application further saves the building cost by changing the specific structure in each building house, and the improvement of the specific structure of the building house in the pig raising system is introduced below.

In some embodiments, the manure pit floor 210 may be a cast-in-place concrete slab, which may be formed in one step during the casting of the concrete of the cast-in-place slab. In some embodiments, the surface of the dung trench floor 210 may be troweled and integrally formed with the concrete slurry.

In some embodiments, in addition to using waterproof concrete for the floor concrete, a flexible waterproof layer may be coated on the bottom of the manure pit (bottom of the cast-in-place slab) and/or the outside of the side walls of the manure pit, so that water leakage problems such as cracks in the concrete slab may be prevented, costs may be reduced, construction period may be shortened, and space inside the manure pit may not be occupied. In some embodiments, the flexible waterproof layer may be a full batch asphalt mastic. In some embodiments, the surface of the bottom plate 210 is finished by using the raw concrete slurry without a leveling layer, a waterproof layer and a protective layer, so that the height of the excrement trench can be increased, the excrement scraper can conveniently shuttle in the excrement trench, and the waterproof layer on the back of the excrement trench is not damaged.

In some embodiments, the bottom layer dung ditch (i.e. the dung ditch on the first floor of the building) can be separated from the building frame structure, and is not attached to the frame structure, so that the self weight of the building frame structure can be reduced, and the building cost can be reduced. In some embodiments, the bottom manure pit side walls may be cast-in-place concrete walls, the bottom slab may be cast-in-place concrete rafts, and a gravel bed is disposed under the rafts. In some embodiments, the clearance height H6 in the bottom layer manure pit is 600-650 mm. In some embodiments, the height H7 of the side wall of the bottom layer dung trench may be 850-900mm, and the wall thickness G2 may be 200-250 mm. In some embodiments, the floor thickness G3 of the bottom layer manure channel may be 120-150 mm.
