Let's learn about the detection methods and prevention points of bovine tuberculosis.

first, the main points of diagnosis of bovine tuberculosis

The symptoms such as progressive emaciation, cough, intractable diarrhea, chronic mastitis, chronic swelling of lymph nodes on the body surface, and rough fur can be diagnosed initially.

Cows with tuberculosis are listless, unwilling to exercise, prone to fatigue or sweating.

The main clinical manifestations are weakness and progressive emaciation.

Its pathological feature is the formation of tuberculous granuloma (tuberculous nodules) in tissues and organs, followed by caseous necrosis or calcification in the center of nodules.

II. Autopsy of Bovine Tuberculosis

(1) Tuberculosis, there are many white nodules as big as millet and pea on the lung surface, and the section is caseous necrosis and calcification, and it feels gritty when cutting.

Because of low body resistance and strong virulence of pathogenic bacteria, some diseased tissues dissolve, forming a paste on the surface, and there are proliferative granulomas on the edge, which can lead to cavities in severe cases.

(2) When tuberculosis occurs in the pleuroperitoneal membrane, the serosa is densely covered with translucent tuberculosis nodules, which are similar to pearls, so it is called pearl tuberculosis.

No matter which tissue or organ has tuberculosis focus, the common feature of * * * is the formation of tuberculosis nodules or granulomas.

Third, the main points of prevention and treatment of bovine tuberculosis

1. Prevention and control principles Strengthen feeding management, regular disinfection, regular quarantine, and immunization when necessary.

Cows should undergo health quarantine twice a year, including tuberculosis and brucellosis. When cows with tuberculosis are found in the group, they should be treated in isolation, and serious cases should be eliminated.

Vaccinate negative cows.

2. Treatment: intramuscular injection of streptomycin, oral administration of isoniazid, p-aminosalicylic acid and cyclic acid.

Note that tuberculosis is a chronic infectious disease, the course of which develops slowly and the treatment takes a long time.

In addition to the payment of drug fees, there are also isolation conditions during treatment. Unless the excellent varieties are considered for isolation treatment, they are generally eliminated.
