The disease is mainly caused by insufficient feeding or incomplete nutritional value of feed during pregnancy and lactation. Postpartum hypogalactia of sow can be caused by premature mating, mammary gland dysplasia or over age, lactation deficiency, mastitis and metritis. In addition, sows suffering from systemic serious diseases, febrile infectious diseases, breast diseases, endocrine disorders, premature mating, breast hypoplasia, etc., can all cause postpartum lactation or lactation insufficiency.
Malnutrition means lack of milk, the sow is thin, the milk secretion is insufficient, the piglets are not full, they often chase the sow for milk, they often scream because of hunger, and they soon lose weight. Some sows have increased postpartum body temperature, loss of appetite, listlessness, stopping breastfeeding or only a small amount of milk, and piglets cling to nipples, hungry and screaming for emaciation; Some sows have normal postpartum body temperature, normal appetite and normal spirit, but the milk yield is small, the milking interval is too long, and the piglets are not full.
The primary measures to prevent the disease are to strengthen the feeding management of pregnant sows and lactating sows, provide them with full-price diets, keep pregnant sows moderately obese, massage their breasts regularly and promote postpartum lactation. For sows with little or no milk after delivery, on the one hand, we should actively treat them, on the other hand, we should do a good job in cultivating piglets or feeding artificial milk to ensure that piglets are healthy and disease-free.
It can be used for treating agalactia or hypogalactia of sows. Each sow can use 10 tablet, once a day, 3-5 times a day.
It can also be treated with the following traditional Chinese medicine prescriptions: Semen Vaccariae, Trichosanthis Radix each 60g, Radix Rhapontici 40g, Bombyx Batryticatus 30g, and trotters, which are decocted in water and fed twice.
For sows with increased body temperature, loss of appetite or abandonment, listlessness, and decreased or stopped lactation caused by the spread of local infection after delivery, penicillin and streptomycin should be injected intramuscularly twice a day for 2-3 days, and cardiotonic drugs 10% caffeine sodium 5- 10 ml should be injected at the same time. If there is inflammation in the uterus, 2 ~ 4 ml of pituitrin is injected subcutaneously or intramuscularly to promote the discharge of inflammatory secretions. It is not allowed to wash the uterus to prevent the infection from getting worse.
