Six methods for observation and diagnosis of Sheep Disease

The mental state and abnormal changes of the sheep were observed directly. Healthy sheep generally scramble for food, running at the same speed and responsive; sick sheep often show herding, stopping feeding, standing or lying on the ground.

Healthy sheep have bright eyes, lively and stable movement, and often show instability or unwillingness to walk when they get sick. Some diseases also show special posture, such as tetanus showing stiff limbs, sheep with cerebral echinococcosis or sheep nose flies turning in circles, limping.

The fat condition generally suffers from acute anthrax, sheep fast epidemic, sheep black disease, sheep sudden onset, sheep enterotoxemia and so on, and the diseased sheep can still be fat and strong; on the contrary, most of the diseased sheep are thin and weak when they suffer from chronic infectious diseases and parasitic diseases.

The coat of wool and skin healthy sheep is smooth, not easy to fall off, shiny; the coat of diseased sheep is often rough, brittle and easy to fall off, such as sheep acariasis often show hair shedding and scab, skin thickening, scratching and scratching. When examining the skin, not only pay attention to the appearance of the skin, but also pay attention to edema, inflammatory swelling and trauma (parasitic diseases: edema in the lower jaw, chest and other parts).

Visual mucosa healthy sheep visual membrane, conjunctiva, nasal cavity, oral cavity, vagina, anus and other mucous membranes are pink, moist and smooth. When the mucous membrane becomes pale, it is a sign of anemia; mucosal flushing is mostly caused by elevated body temperature and heat venereal diseases; mucosal yellowing indicates increased bilirubin in the blood, bile duct obstruction in liver disease or hemolytic anemia. If suffering from sheep bursal disease, Fasciola hepatica and so on, the visible mucous membrane shows varying degrees of yellow staining phenomenon; when the color of the mucous membrane is purplish red (also known as cyanosis), it indicates the increase of reduced hemoglobin in the blood and the sign of severe hypoxia. It is common in the critical stage of respiratory difficulties, toxic diseases and some diseases.

The examination of appetite for ruminant directly reflects the health status of the whole body and digestive system of the sheep. The abandonment of diet indicates that the condition is serious. If you eat and dare not chew, you should check for oral and dental abnormalities. Healthy sheep usually have a wet nose and begin to regurgitate half an hour after feeding. Each rumination lasts for 30 ~ 40 minutes, chewing 50 ~ 70 times per food ball, and 6 ~ 8 times a day and night. Dry nose, reduced or stopped ruminating, mostly due to high fever, severe forestomach and true gastrointestinal inflammation; febrile venereal disease often shows increased drinking desire in the initial stage.
