How do you know if a sheep is sick? Experts teach you "five look" to recognize sheep disease, so that you can find timely treatment!

Sheep is also known as sheep or Aries. Hairy four-legged ruminant that is one of the livestock of human beings. However, in the process of breeding, improper management is easy to cause the occurrence of sheep disease, and many farmers also caused a lot of losses because they failed to find and treat them in time. Here Professor Wang of Dali Agricultural Technology Station tells us how to judge whether the sheep is sick or not. The vast number of farmers have to take a closer look!

One, posture. Healthy sheep generally compete for food, running speed is uniform, response to Meijie, sick sheep are slow to respond, stop eating standing or lying on the ground. Some diseases can also cause sheep to show special posture, such as tetanus, which shows stiff limbs, and sheep with cerebral echinococcosis have symptoms such as turning in circles.

Measures: 1. Preventive injection. Tetanus toxoid is an effective biological agent to prevent this disease. For the prevention of lambs, it is more appropriate for ewes to be injected with tetanus toxoid in the later stage of pregnancy.

2. Trauma management. In the event of trauma to any part of the sheep, iodine or 2% red mercury should be used to strictly disinfect the wound, and soil and feces should not invade the wound.

3. Injection of anti-tetanus serum. Early application of anti-tetanus serum (tetanus antitoxin). A sufficient dose (200000 ~ 800000 units) can be used at a time, or the total dosage can be injected subcutaneously, intramuscularly or intravenously, or half intravenously and half intramuscularly. The anti-tetanus serum can be retained in vivo for 2 weeks.

Second, fat feelings. When sheep suffer from chronic infectious diseases and parasitic diseases, most of them are thin.

The common internal and external parasites of sheep are intestinal tapeworm, Fasciola hepatica, intestinal sarcoidosis, hookworm, whipworm, pulmonary filariasis, scabies, sheep nose fly, sheep lice, ticks and so on.

Parasitic diseases in sheep mainly enter the body of sheep through food or water. Therefore, it is very important to control the quality of sheep feed and drinking water.

Measures: 1. Select suitable areas for grazing. Try not to choose low-lying, humid and sunny areas for grazing, and you need to develop reasonable grazing plans to reduce the frequency of grazing in the same area.

2. Strictly control the source of drinking water. Sheep should be allowed to use live water during grazing.

3. Improve the health ability of sheep. Daily feeding and management should be strengthened to ensure reasonable nutritional needs and adequate and clean food, so that the resistance of sheep can be improved to a certain extent.

4. disinfect the enclosure regularly and disinfect the enclosure regularly.

Third, coat and skin. The coat of healthy sheep is smooth and not easy to fall off, while the coat of diseased sheep has nothing to do with rough hair, brittleness and easy shedding, especially mustard mite disease, which can lead to hair shedding, scab and even trauma.

Measures: 1. When buying sheep, they must be inspected or quarantined for a period of time (20-30 days) to confirm the presence of acariasis.

2. Keep the enclosure clean, dry, ventilated and transparent, especially in summer, we should pay attention to moistureproof and prevent excessive humidity.

3. Pay attention to daily disinfection, spray disinfection in time, keep the enclosure sanitary, and strengthen feeding management.

4. The environment around the sheep house should be clean and hygienic, prevent the invasion of outside animals (especially rats), and remove all conditions under which pathogens may be carried, preserved and spread.

Fourth, mucous membrane. Healthy amniotic conjunctiva, nasal cavity, oral cavity, anus, and other visual mucosa are pink, moist and smooth. Mucous membrane becomes pale, it is a sign of anemia; mucosal flushing, mostly caused by elevated body temperature, caused by thermal venereal diseases, mucosal yellowing, then increased bilirubin in the body, hepatic bile duct blockage, or hemolytic anemia. If suffering from bursal disease, fascioliasis, and so on, the visible mucosa show varying degrees of yellow staining. Visible mucosal cyanosis, in view of respiratory difficulties, toxic diseases and critical stages of some diseases.

Fifth, feed and regurgitate. The abandonment of diet means that the condition is serious; if you eat but do not chew, you should check your mouth and teeth. The nasolabial mirror of healthy sheep is moist and begins to regurgitate half an hour after feeding, once for about half an hour, 6-8 times a day and night; nasolabial mirror is dry, ruminating decreases or stops, mostly caused by high fever and severe inflammation of forestomach and true gastrointestinal tract.
