Description
Technical Field
The application relates to the technical field of animal feed, in particular to a feed for improving the mammary gland development and postpartum agalactia of a sow and a preparation method thereof.
Background
The sow has no or little milk after delivery, and the main reason is that the sow is not fed enough or the feed nutritive value is too low during the pregnancy and lactation period, so that the sow is malnourished; immature sow, premature hybridization, dysplasia of mammary gland, or over-aged and hypofunction of mammary gland; and sow diseases such as systemic severe diseases, infectious diseases, breast diseases, endocrine dyscrasia and the like can cause no milk and insufficient milk secretion.
The postpartum sow has no milk and insufficient milk yield, which is reflected in that the number of times of milk intake of the piglets is increased but the piglets are not full, the sows are often pursued to suck the milk, the piglets are hungry and have hoarseness due to the fact that the piglets cannot eat the milk and begin to lose weight. The breasts of sows usually have no obvious change, sometimes the breasts can be seen to be loose, the mammary glands are not developed, and milk cannot be squeezed out or the milk quantity is little when milk is squeezed by hands.
At present, when the symptom is treated, antibiotics are mainly used for treating, and the lactation function is improved through nerve and body fluid regulation, so that the method often causes the excessive medicines, the meat quality is influenced, and the irreversible harm is easily caused to the human body when people often eat excessive pork with excessive hormone medicines.
