In the process of industrialized swine production, in order to increase the utilization rate of swine housing and pig production efficiency, the method of all-in, all-out, and balanced production is generally adopted, and production is conducted with a weekly rhythm, that is, a certain number of sows are kept. To form a production line, each production line consists of breeding, pregnancy, delivery, conservation, growth, and bred. Taking the production line of 10,000 heads of 600 basic sows and 10,000 heads of commercial pigs for example as an example, and with an average annual output of 2.1 litters per sow, 1260 litters can be produced each year, with an average of 24 litters per week. Each production line is composed of breeding houses, gestation houses, branching houses, nursery houses, growing houses and breeding houses. The size of each house depends on the number and arrangement of pig houses in each type of house. First, the number of various types of pigsheds in the production line Factory pig raising is based on the rhythm of the week and the feeding unit as the unit, implementing the all-in and all-out production system. Thorough cleansing and disinfecting should be carried out after all out. Taking account of the imbalance in the actual production process and the convenience of management, each barn should also be provided with a certain number of mobile bars. Usually, the number of pigs per week is increased to facilitate flushing. Use when disinfecting and maneuvering. 1. Boar Bar: In industrial pig production, the ratio of male to female pigs is 1:20. Taking the 10,000-head production line as an example, 30 boars need to be kept. Therefore, 30 boar stalls should be set in the breeding house. The boar's annual turnover rate is 50%, and 15 boars should be renewed every year. Therefore, it is necessary to set 4 to 5 backyards. 2. Sow pens: Because the sows circulate between the breeding house, gestation house, and delivery house on the production line, the number of sows in each house depends on the time the sow spends in each house. (1) Time for the sow to occupy the stalls in the breeding house: The sows are transferred to the breeding house after weaning, usually after 4 to 5 days of estrus breeding, averaging about 7 days. After one breeding period, the estrus cycle is no longer estrus. Transfer to pregnancy room. So the time the sow is in the breeding house should be equal to the number of days from weaning to breeding, plus the number of days of an estrus cycle, ie 4 weeks. (2) Time for sows to occupy the pens in the gestation room: The gestation sows enter the delivery room about one week before delivery, so the time in the gestation room should be 114 days minus one estrus cycle, minus one week, ie about 12 weeks. . (3) The time the sow is in the farrowing room: equal to the lactation period plus one week. If the weaning period is 28 days, the sow's time spent in the farrowing room should be 5 weeks. After determining the sow's occupancy time in each house, the number of sows in each house can be calculated. Taking the 10,000 head sow production line for 600 basic sows as an example, the number of sows in the farrowing house is 5 weeks. The number of sows in the farrowing house should be: (5 + 1) 24 = 144 columns. The number of sows in the breeding house is: (4+1)24=120 columns. The number of pregnant sow pens is: (12 + 1) 24 = 312 columns. 3. Nursery house piglet fence: The piglet enters the nursery house after weaning. The time for the nursery house is about 5 weeks. When the weaning pigs are put together, the two adjacent litters are transferred into a nursery. Therefore, the number of nursery pens should be halved. The area of ​​each column can accommodate two litters of piglets, so the number of nursery pens is: (5 + 1) 242 = 72 columns. 4. Growth sheds: The weight of pigs entering the growth house has been more than 20 kg. At this time, males and females need to be reared in groups. The number of breeding heads in each pen should be 15 to 20 (ie, the number of heads of 2 litter piglets). The median time for pigs in the growing house is about 9 weeks, so the number of pigs in the growing house is: (9+1)242=120 columns. 5. Breeding sheds: From the growing house to the bred house, in order to reduce the stress of regrouping, the entire column should be moved as far as possible. The time for the pigs to grow in the nursery is about 8 weeks, so the number of pigs in the rearing house is: (8+1)242=108 columns. Second, the arrangement of pigs in each pig house In the same production line, the length of each pig house should be basically the same, and should not be too long, 60m ~ 85m is appropriate. Excessive length of the pig house can cause inconvenience to sewage, feeding, and mechanical defecation. 2. The width of the pig house should be conducive to construction, lighting, ventilation and insulation, preferably within 15 meters. 3. The arrangement of the pigskin should facilitate the installation and operation of the machinery. 4. According to the number of pigs, the number of pigs can be arranged in 2 to 4 columns. If the number of pigs is too large and one pig can not be accommodated, it can be divided into 2 to 4 pigs. 5. The male and female pigs in the breeding house should be arranged opposite or adjacent to facilitate stimulation of the estrus of the sow. 6. In order to facilitate the cleaning and disinfection and the implementation of all-in and full-out, the branch house should try to make 24 columns as one unit, and the nursing house should have 12 columns as one unit, and the units should be isolated. Other pig houses try to make a group of 24 columns or 12 columns.
