I believe that many sheep farmers know that sheep pox, commonly known as sheep smallpox, is an acute, heat, and contact infectious disease caused by sheep pox virus. It occurs all year round, but it happens mostly in the spring and autumn. Once the flock is infected, there is a high mortality rate and it will cause most of the diseased sheep to lose their productive capacity. So what are the symptoms of sheep pox, how to prevent it?
First, the symptoms of sheep pox
Sheep pox generally has obvious symptoms. The latency of sheep pox is 6-8 days on average, and the course of disease is about 2-3 weeks. Lambs are more susceptible than adult sheep. In the early stage of sheep pox disease, the body temperature rises, generally 40-42 ° C, the diseased sheep appear less food, anorexia, appetite abolished, listlessness, conjunctiva, eyelid swelling. After 2-3 days, the diseased sheep showed a piece of soybean or broad bean-sized hard acne granules in the hairless or hairy parts of the diseased body, followed by purulent and crusted, and the sick sheep body quickly lost weight, accompanied by respiratory suffering, secondary infection. Diseases such as sepsis, severe 4-5 days of death.
Second, the incidence characteristics of sheep pox
Under natural conditions, sheep pox can only infect sheep, goat pox can only infect goats, and sheep and goats cannot infect each other. Initially individual sheep developed, and gradually spread throughout the group. Goat pox usually invades individual flocks, and the disease and loss are lighter than sheep pox. Mainly through the respiratory tract infection, blisters and clams are easily mixed with fly ash or feed to inhale into the respiratory tract. The virus can also invade the body through damaged skin or mucous membranes. Human utensils, hair, skin, feed, bedding, etc. can all become indirect vectors. The disease is mainly prevalent in late winter and early spring. Factors such as severe cold weather, rain and snow, frost, hay season, poor management and feeding can all contribute to the onset and aggravation of the disease.
Third, the prevention and treatment measures of sheep pox
1. Do a good job of raising and managing the sheep. The circle should be cleaned frequently, kept dry and clean, and grasp the autumn scorpion. Winter and spring seasons should be properly supplemented for cold and winter work.
2, in the area of ​​sheep pox often, regular annual vaccination, sheep pox chicken embryo attenuated vaccine, the size of the sheep will be injected into the tail or femoral endothelium 0.5 ml, goat subcutaneous injection 2 ml.
3. When sheep pox occurs, the sick sheep will be isolated immediately, and the sheep pen and management equipment should be disinfected. For sheep that have not yet developed disease, an acute injection of sheep pox chicken embryo attenuated vaccine is used.
4, for sheep pox using their own blood therapy can stimulate the lymphatic, circulatory system and organs, especially the reticuloendothelial system, so that it plays a greater role, promote tissue metabolism, enhance the body's systemic and local response.
5, symptomatic treatment of skin lesions, such as washing with 0.1% potassium permanganate, iodine glycerin, purple syrup. For fine wool sheep and lambs, in order to prevent secondary infection, you can intramuscularly inject 800-1.6 million units of penicillin, 1-2 times a day, or 10-20 ml with 10% sulfadiazine, and intramuscularly 1-3 times. Treated with healing serum, 10-20 ml for the big sheep and 5-10 ml for the lamb, subcutaneously, and the amount of prevention is halved. It is better to use immune serum.
The above are the symptoms and prevention measures of sheep pox. Farmers must carefully observe the process of raising sheep. Once sheep pox is found, it will be treated in time to avoid unnecessary losses.
