1. Many sow farmers often encounter sows' refusal to feed when sows are fed. They should adopt different methods to adjust and reject sows for different situations. (1) Keep the delivery room quiet. Out of the breeder and the production veterinarian, other strangers should not enter the pig house delivery room, and do not make loud noises. (2) Do not intimidate the sow. The sows that are close to refusal to feed should first whisper warmly and call slowly, and then gently approach the breast with patience. Do not rush to scare. (3) The number of suckling piglets varies from small to large. When the sows are quiet, they can start with 2-3 piglets and gradually increase until they have all consumed colostrum. The piglets should be laid lightly during feeding and try not to let the piglets make a call. (4) To group milk, sows have more litters and when the nipples are not enough, the piglets can be divided into strong and weak, two groups, alternating feeding, weak feeding, or other sows to breed some piglets. (5) Injection of sedative drugs. After the above methods patiently training 2? 3 days later, if still not ideal, can be injected intramuscular injection of chlorpromazine hydrochloride injection, the amount of 2-3 mg per kg body weight of sows, and manual care. 2. Control of non-pathological refusal of sows. Sows often undergo refusal after giving birth, manifesting as normal sows’ udder, appetite, and body temperature, but refusing to suckle piglets and even killing the piglet. In this case, isolate the piglets first, then 2-3 ml of 1% procaine hydrochloride per kilogram of body weight in the neck, wait until the sow is quiet, then grasp the piglets to the sow's nipple for sucking. After 1-2 training sow habits can be restored to party breastfeeding.
