1. Causes of insufficient milk: The common causes of insufficient or no milk for sows after delivery are: ① improper feeding management of sows during pregnancy and mammary gland dysplasia; Feed during pregnancy should follow the pattern of "high, low and high" to ensure reasonable control of feeding amount and comprehensive nutrition. If sows overeat in the second trimester of pregnancy (30-85 days), high concentration of free fatty acids and low concentration of branched-chain amino acids will appear in the blood of obese sows, which will act on the appetite center of the brain, reduce the intake during lactation, and eventually lead to a decrease in milk production. Secondly, neglect of feeding sows in the third trimester of pregnancy often leads to emaciation, mammary gland dysplasia and shriveled breasts of sows, thus limiting lactation capacity and leading to insufficient postpartum milk. ② Sows are old and frail, and their physiological function declines; ③ Early mating age of sows and mammary gland dysplasia; (4) Purebred sows will suffer from unexplained milk deficiency or lack of milk; ⑤ Sows are obese, with excessive breast fat deposition and endocrine disorders; ⑥ sow's resistance is poor, and the confinement is not clean, causing mastitis. Second, when the sow's milk is not enough, the following measures can be taken: first, find a surrogate sow; Second, artificial water feeding (milk or milk powder); The third is to improve the milk yield of sows by using the following formula: 1. Feeding raw milk spirit (for human use), the dosage is 2-5 times of human consumption, divided into 2-3 times; 2.
