Causes and solutions of postpartum milk deficiency in sows

Sow breast-feeding

Sows, especially parturient sows, are prone to underlactation during lactation. If the sow's breast is not full and the piglet's coat is not smooth, every time the piglet is breast-fed, the piglet has to arch milk, while the sow lies down or sits as a dog and refuses to breast-feed, which is a sign of lack of milk. The main reasons for lack of milk or lack of milk are:

Cause analysis

1. Improper feeding of sows during pregnancy, resulting in overweight or emaciation of sows, hypoplasia of mammary glands, resulting in little or no milk.

two。 Sows are younger and their mammary glands are not well developed, so there is no milk.

3. If the sow is too old and its physiological function decreases, there will be less milk.

4. Sows have digestive tract diseases, loss of appetite, poor digestion and absorption, it is easy to lack milk or less milk.

5. Sows are subjected to external stimuli such as high temperature, noise, forced eviction, shock and other stress reactions, resulting in endocrine disorders, sows produce little or no milk.
