Prenatal: Feeding sows a few days before their farrowing is mainly determined by the condition of the sow and the development of the breast. Sows with better body condition and breast growth should be reduced 3-5 days before birth, gradually reduced to half or one third of the level of late pregnancy, and stop feeding green feed and fermented feed to prevent excessive milk secretion. Causes mastitis, or causes piglets to squat due to excessive milk. Thinner sows do not need to be cut. If the breasts do not swell enough in the first few days, you should add some protein-rich prolactin feed. Postpartum: On the day of farrowing, the sow is very tired, does not want to eat, feels thirsty, can feed clean drinking water, or feed salted bran water. After 2-3 days after farrowing, the nursing sow must be given special care. First, the uterus should be returned to normal state. At this time, it is not possible to use large-volume feed; second, excessive milk secretion should not be avoided, and piglets cannot eat all of the piglets. This leads to mastitis. If sows are lean, have little or no milk, they can be fed with animal feed, or they can be given prolactin. There are three formulas: First, four eggs, 500 grams of peanuts, add water, cooked, fed twice in two pigs, generally in 2-3 days after the milk; the second is 250 grams of kelp bubble rose chopped, add 100 grams of lard Soup, feed once a day sooner or later, even feed 3 days; Third, a chopped pig intestines cooked, add a little salt to cook, even soup with intestinal feeding pigs. Within 5-7 days after sow farrowing, the nutritional status of sows with good body condition should not be too high, and the feeding amount may gradually increase. Within 10-15 days after delivery, gruel feeds should be fed. If thick porridge or dry foods are fed, clean drinking water should be provided. In the 3-4 days postpartum, the sows can only allow the sows to rest in the laps after the postpartum period. After the fourth day, if the weather is clear, the sows can move out of the circle and the piglets can be kept in the pen. After the sow is active, it enters the circle to raise piglets.
