(1) Feeding of lactating sows: Because sows secrete a large amount of milk during lactation to maintain the growth and development of piglets, during feeding, it is necessary to pay attention to feeding sows more feed conducive to lactation, such as adding some fish meal, bean cake (meal) and high-quality green juicy feed, and fully supplying clean drinking water, increasing feeding times every day and feeding less at each meal. Generally, feed it 3 ~ 4 times a day, with even intervals. Be careful not to let pigs eat too much at a time to avoid indigestion. The feeding of lactating sows should not only be regular and quantitative, but also need diversified feeds to meet nutritional needs. 3 ~ 5 days before weaning, the feeding amount of concentrated feed and juicy feed of sows can be gradually reduced.

(2) Management of lactating sows: each row of lactating sows should be 1 head. Due to the postpartum sow's physical decline and poor appetite, it is necessary to stay in the bar to rest and recuperate. Activities can be released in 3 ~ 5 days. After 7 days, in sunny weather, sows and piglets can go out to eat grass, dig soil, eat grass and bask in the sun to promote blood circulation and digestive function. The feed trough must be cleaned once a day, and the mat should be changed frequently to keep the pen house clean and dry. Train sows to form the habit of lying on both sides alternately, which is convenient for piglets to breastfeed.
