Prevention and treatment of bovine tuberculosis

A variety of diseases often occur in cattle, and the diseases that occur in different cattle breeds are different, but there are some common diseases, which are either lethal or common. Bovine tuberculosis, which is introduced in today's article, is a serious disease that can infect humans. It is an important animal disease for prevention and control.

I. types of diseases and infections

There are three types of bacteria, showing different symptoms of infection and different ways of reproductive infection, mainly according to the object of infection, there are cattle type, human type, poultry type, then mainly talk about the cattle type bacteria infected cattle. The bacteria need oxygen to grow, are sensitive to acidity and alkalinity, and can survive in the range of 5.9 to 6.9. Can survive in the soil for 7 months, afraid of high temperature, bleach, formaldehyde control is effective. The disease is mainly transmitted through the respiratory tract.

Second, the expression of susceptibility to disease

Cows and buffaloes are most susceptible to disease and are easily transmitted by other animals. The disease has an incubation period of about half a month. During the first performance of emaciation, shortness of breath. In the later stage, according to the different symptoms of the main infection site of the bacteria, pulmonary tuberculosis will have cough and auscultation with friction sounds; lymphoid tuberculosis, there will be lymphatic enlargement around the chin; breast tuberculosis, less milk, breast swelling, caking; intestinal tuberculosis will show symptoms of dysentery.

III. Prevention and control methods

1. Quarantine

The cattle are quarantined regularly every year, and the cattle are quarantined and treated immediately when they find problems, and then return to the herd after they are restored to health. when buying breeding cattle, they should be quarantined once, quarantined and observed for a month, and then quarantined again. Only when they are free from disease can they enter the farm and raise them together. Patients with tuberculosis should not be allowed to enter the farm.

two。 Disinfection

Every year regularly thoroughly disinfect, clean the entire farm, usually clean the cattle pen every day, regularly clean up the feces and other dirt of the farm, spray powder after cleaning the farm floor, and wash the body of the cattle when cleaning the ground. Food utensils should be sterilized at high temperature regularly.

3. Epidemic prevention

Check once a month, it is found that sick cattle can be isolated and treated in time, and seriously sick cattle can be killed directly. At ordinary times, cattle suspected to be susceptible and cattle with poor performance should be isolated in time, and healthy cattle should be raised separately from suspected cattle. Be careful not to mix sick cattle with healthy cattle. Diseased cattle need long-term treatment and revisit many times.

Bovine tuberculosis is easy to form different pathological reactions in different parts of the body, so the harm is more serious, and the treatment is not easy. Tuberculosis is a disease that is not easy to be eliminated after infection. Generally, the disease period is very long, and the treatment is easy to be repeated, so it can be said to be completely eliminated only after a number of revisits after long-term treatment.
