How should pig raising equipment be arranged in different pens?

The specifications of different pens in the pig farm are different. The pig raising equipment should be arranged reasonably according to the construction structure of the pig house, so as to develop the good performance of the pig raising equipment!
1、 Boar house and breeding house
Most of the boar houses are single row type with sports floor. The height of the ring wall or ring fence is 1.2-1.5m, and the ring area is 7-9m2. The area of the sports field can be 1.0-2.0 times of the ring area. All the boars were raised in single ring.
2、 Empty and pregnant house
Single row or double row, open or semi open type with sports ground are also adopted, which can be raised in groups or fed alone. In group breeding, there are 4-6 empty sows per circle and 2-4 pregnant sows per circle. The sows were fed by single feeding (limited feeding). Because the single feeding pens in group breeding adopt the method of locating feeding in separate bars, the uniformity of feeding among individuals is solved, and the sows have sufficient movement. However, under intensive conditions, pregnant sows are usually raised in a high-density, location-based way, and the piggery is in a double or multi row, open or semi open way. Most cages adopt single metal limit bars.
Three. Delivery house
In order to meet the requirements of suitable temperature 16-18 ℃ for sows and 29-32 ℃ for suckling piglets, the outer structure is closed, and the cage is high bed delivery cage. The middle part of the bed is the limit area of sows (generally 0.60-0.65m wide), and the two sides are the active area of piglets. In the high bed metal fence, there are sows' feeding trough, sows' and piglets' automatic water dispensers, heat preservation boxes and piglets' free feeding and feeding trough.
4、 Nursery
After weaning, the piglets should be transferred to the human care house to provide a dry, warm and clean indoor environment: one nest, one circle or mixed group can be used. The modern intensive breeding on the ground or in the high bed mostly adopts all metal fence. The single fence is 2.0m long, 1.7m wide, 0.6m high, 30cm high from the bed bottom to the ground, and the fence bar spacing is 6cm. The bed bottom is provided with 1 / 2 cement solid floor and 1 / 2 leakage board. Solid floor is convenient for eating and sleeping, and leaky floor is convenient for excretion of feces and urine.
5、 Growth and finishing house
Most of them are raised in groups on the ground, with 8-12 pigs in each circle. The area of the pens and the width of feeding depend on the number of growing and finishing pigs.
