It takes "10 looks" to observe diseased pigs.

At present, in terms of feeding and management, some people pour their feed into the pig trough and go away, paying little attention to the growth and development of pigs and whether there is any morbid performance. As a result, pigs are not aware of the disease. After the pigs are turned upside down, it is too late and difficult to treat. In order to achieve early prevention and treatment of diseases, the symptoms must be found in time, and can be observed from the following ten aspects.

First, look healthy pig spirit is good, tail up and swinging freely, sick pig is mental wilting, slow action, like lying motionless, tail drooping.

Second, the appetite of healthy pigs is exuberant, such as sudden loss of appetite, abnormal eating habits, or even stopping eating is a morbid performance, if the appetite is reduced, like drinking water, it is mostly heat venereal diseases.

Third, look at healthy pig fur smooth, elastic skin, if the fur is dry and rough, it is malnutrition or disease, if there are erythema or red spots on the skin, it may be infectious diseases such as classical swine fever, swine erysipelas, swine lung disease or porcine paratyphoid, if the skin is thick and rough with falling debris and itching, it is mostly scabies and eczema, if there is abnormal hair removal and baldness, often chronic diseases and skin diseases.

Fourth, look at the healthy eyes of the pig, the eyes of the sick pig are bright and divine, there are tears, shit, conjunctival congestion and flushing.

Sixth, look at the nasal process, the nose process is clear, clean and moist as a disease-free pig, with some dryness or cracks, mostly a sign of high fever and severe dehydration.

7. The body temperature of healthy pigs is generally 37.5 ℃-38.5 ℃. If the body temperature is too high, there are many infectious diseases. If it is too low, it may be malnourished, anemic, parasitic or dying.

Look at the feces of healthy pigs, the feces are soft and moist, conical, without special smell, if the feces are dry, hard, small, mostly febrile venereal diseases, the feces are as thin as water or mud, the number of defecation increases significantly, or fecal incontinence, mostly enteritis, intestinal parasite infection, piglets excreted gray-white, grayish yellow or yellowish-green water-like feces with fishy smell, for piglets white dysentery. Classical swine fever, swine erysipelas, swine lung disease and other infectious diseases, feces often mixed with mucus pus and blood and so on.

Look at the urine of healthy pigs, the urine of healthy pigs is colorless and transparent, there is no abnormal smell, and the urine of diseased pigs is less and yellow.

Ten, the sleeping posture healthy pig generally sleeps on the side, the muscle is relaxed, the breathing rhythm is uniform. Sick pigs often stick their whole body to the ground, sleep wearily, and sit like a dog if they have difficulty breathing.
