Breeding sows
1. Empty period. Sows generally have poor sensation and weak constitution. It can be fed for a short period of time to promote it. Feed with full-priced compound feed. The formula is: corn 45%, barley 18%, dried sweet potatoes 20%, bean cake 10%, rice bran 4%, fish meal 1.5%, bone meal 1%, salt 0.5%. When the sensation increases to 50% to 60%, the pig can ovulate ovulation and give it a timely manner. 2. Pregnancy. Use step-up breeding methods. The early stage of pregnancy is based on roughage, and proper addition of concentrate is sufficient. In the middle of pregnancy, it is necessary to meet the needs of the fetus for nutritive substances, but also to prevent the sow from overly suppressing the growth of the fetus. Late pregnancy requires a lot of nutrients. The diet formula is: 2.5 kg of corn, 0.5 kg of bean cake, 0.25 kg of sweet potato, 1 kg of barley, 0.5 kg of sorghum, 25 g of bone meal, and 15 g of salt. 3. During the lactation period. Use two less feeding methods. Sows should be fed less during the first 10 days of litter to prevent over-promoting lactation, indigestion of young pigs, and excessive milk prone to sow mastitis. During 10 to 50 days of litter size, the piglets develop rapidly and require a large amount of breast milk. The sow's diet should be increased nutritionally. When the piglet is about to be weaned, it is necessary to gradually reduce the amount of sow feed and reduce the quality of the feed in order to reduce lactation and promote weaning of piglets.
