First, according to the age of the pigs, do a batch of immunization plan, limited feeding and feeding plan, deworming plan and implement it. The gilts were paired with the precursor parasites in vivo and once for injection of JE, parvovirus, swine fever, and foot-and-mouth disease vaccines. Second, feed 2 times a day. Restricted feeding and feeding programs: sows are free to feed before 6 months of age, and are appropriately limited by 7 months of age, and they are fed for the first month or half of the month before mating. The feeding amount is controlled to be less than 2 kilograms for feeding restrictions, 2.5 kilograms or more for free feeding. Third, make a backup pig estrus record, and transfer the record to breeder staff. The sow estrus record begins at 6 months of age. Observe the initial estrus time carefully so that the estrus can be bred in time for the second or third time and record it. 4. Reserve boars are reared on a single bar, and when the pens are not enough, 2 to 3 columns can be used, and the barn can be reared for 1 month. A small group of gilts reared, 5 to 8 heads. Fifth, the introduction of spare pigs for the first week, the feed properly add some anti-stress drugs such as vitamins, vitamin C, multi-dimensional, mineral additives. At the same time, some antibiotics such as Hunuojing, Huchangshu, Taichaojing, doxycycline, lignomycin, oxytetracycline, etc. are properly added to the feed. 6. The effective isolation period for outlying pigs is about six weeks, that is, the introduction of spare pigs is to be kept at least for 40 days in the isolation room. If you can turn around, it is best to keep one month before mating, that is, 7 months of sow and 8 months of boar. Before going into the production line, it is best to have polyculture with the old sow or the old boar for more than 2 weeks. 7. Reserve pigs feed 2.0 to 2.5 kg per head per day, and increase or decrease the feeding amount according to different body conditions and breeding schedules. In the first estrus period, the gilts must be arranged to feed more than one-third of the prescribed amount, and the amount of feed after the gilts is reduced to 1.8 to 2.2 kg. VIII. The gilts entering the breeding area are placed on the playground for 1 to 2 hours a day and checked with boars. Nine, the following methods can stimulate the estrus of the sow: tuning; and contact with different boars; as far as possible close to the estrus sows; appropriate exercise; restricted feeding and superior feeding; application of hormones. Tenthly, gilts that are not in heat for more than 60 days after entering the breeding area should be eliminated. 11. Gravid gilts with asthma, gastroenteritis, and limb and leg diseases should be kept separately in one column; this column should be at the end of the pig house. Observing and treating the two courses of treatment have not seen any improvement and should be eliminated in time. 12. The gilts were transferred to the breeding house at 7 months of age. The gilt's initial mating age must reach 7.5 months of age, with an important body weight of 110 kg or more. The boar's initial mating age must reach 8.5 months of age, with an important body weight of more than 130 kilograms.
