When sows have less milk after giving birth, they will develop the disease within 12h to 3d after giving birth, showing soft or swollen breasts. Pig B-ultrasound is needed to examine their breasts and then treat them. They have no response to the piglets' sucking requests, are emotionally indifferent, like to lie prone, and the piglets suckle for a longer time, often hitting and pulling the nipples with their mouths. Piglets become thin due to lack of water and malnutrition, with dry noses and rough and messy back hair. The skin is pale and dull, the feces are small and dry, and they are sleepy and weak. Sows with lack of milk or no milk are generally easy to diagnose through a series of clinical manifestations and piglets' hunger and dehydration and epidemiological analysis, but pig B-ultrasound is also needed to assist in diagnosis. The key is to discover in time and treat in time.

There are many reasons for sows to have less milk after giving birth through pig B-ultrasound. ① If the sow is bred too early, the mammary glands of the primiparous sows are not fully developed, which leads to the hormone and nerve dysfunction that promotes lactation. Therefore, pig B-ultrasound should be used to conduct a comprehensive examination of their reproductive organs during breeding. ② Failure to provide the sow with complete feed to meet its nutritional needs during pregnancy, especially in the late pregnancy, without supplementing concentrate as needed, can directly lead to postpartum weight loss and agalactia. ③ Excessive nutrition and high energy lead to sows being too fat, resulting in blood stasis, poor meridians, and diseases. ④ Sows have been frightened and strongly stimulated during lactation, which inhibits the sow's lactation function. ⑤ Sows are infected after delivery, and have systemic symptoms such as fever, loss of appetite and lack of energy, which can also lead to disorders in lactation function. Diseases such as mastitis caused by Escherichia coli, Staphylococcus, etc., systemic diseases and metritis can cause the disease. When the disease occurs, pig B-ultrasound must be used for diagnosis.

Including mastitis and other diseases, sows with mastitis can be seen with hard lumps in the affected part of the breast, reddening of the skin, fever and pain. The sows do not allow the piglets to suckle, which sometimes spreads to the entire breast. The sows become depressed, have a fever, and have a loss of appetite. The treatment principle is to clear away heat and detoxify, and to activate blood circulation and remove blood stasis.
