One, the main reason
1. The sows have poor nutrition during the late pregnancy, the pigs are thin, and the mammary glands are not well developed. 2. Sows feed too much energy during pregnancy, and other types of feed are insufficient, and pigs are overweight and endocrine disorders. 3. Early mating sow mating prematurely, incomplete breast development, prolactin and neurological disorders. 4. Sow elimination rate is too low, too old, appetite is not strong, digestion and absorption is not good. 5. Poor sows, postnatal infections and other diseases; 6. Stress causes lack of milk or lack of milk.
Second, prevention and control measures
1. Strengthen the sow's late pregnancy nutrition to ensure that the mammary gland is well-developed.
2. Reduce the energy feed the sow feeds during pregnancy and add other types of feed to prevent pigs from becoming obese and endocrine disorders.
3. To prevent early maternal sows from mating prematurely, with a first-day maternal age of 240 days or more and a body weight of about 100 kg.
4. Eliminating old sows in time.
5. Enhance the sow's constitution and prevent postpartum infections such as production tract infections.
6. Reduce stress response.
7. Pay attention to cleaning and disinfecting sows. The sow was cleaned one week prior to the onset of labor, and 0.1% potassium permanganate solution or benzalkonium was used to sterilize the sow, especially its udder, ventral and buttocks, and then into the clean and disinfected delivery room.
8. Massage the breasts. The postpartum sow's breasts are massaged 3 to 5 times a day for 15 to 30 minutes and milked every 10 to 10 minutes.
9. Drug prevention: sodium sulphate 1.5 to 2.0 kg/t is added to feed, sows, sulfamethoxazole, trimethoprim and sulfathiazole are given 3 to 5 days before delivery to reduce postpartum mastitis happened.
10. Western medicine treatment: 1 application of prolactin tablets prolactin, each 50, 2 times a day orally, once every 2 to 3 days. 2 On the day of prenatal and on the postpartum day, 10 ml of sodium selenite vitamin E injection was injected intramuscularly to the sow. 3 hormone therapy: intramuscular injection of 4 to 5 ml of diethylstilbestrol, 2 times a day; there is milk and poor lactation 5 to 6 ml of intramuscular injection of oxytocin, 2 times a day, or intramuscular injection of pituitrin 5 ~ 6 ml twice daily for 2 days. 4Promote lactation and eliminate inflammation by intramuscular injection of antibiotics such as penicillin and streptomycin or sulfa drugs.
11. Traditional Chinese medicine treatment: Traditional Chinese medicine has excellent results in the treatment of traditional Chinese medicines such as royal jelly, pangolin, etc. The following reference prescriptions can be used in production: 1 Vaccaria 35 g, Pangolin 35 g, Decoction 250 g (mash), add 200 grams of brown sugar, 1 seasoning feed, one dose per day for 2 to 3 days. 2 15 cases of chrysanthemum spirit, 1 oral administration, or pass milk scattered 100 grams, 2 times service, 1 time a day. 3 King No. 45 grams, Chuanxiong 25 grams, pass grass 25 grams, Angelica 35 grams, 25 grams of Codonopsis, peach kernel 20 grams into the end, add 3 eggs for feeding service. 4 200 grams of brown sugar, 200 grams of rice wine, 2 eggs, stir in the feed and feed the pigs, and even feed 3 to 4 days.
