Prevention and treatment of abortive disease in cattle

Cattle septicemia is an infectious disease caused by Pasteurella multocida and characterized by septicemia and hemorrhagic inflammation of tissues and organs, so it is also called bovine hemorrhagic disease.

Septicemia.

1 symptoms: inflammatory edema of head and neck, throat and chest often occur in diseased cattle. The disease is called swollen neck, ringing neck, lock-in and so on. Cattle failure is a common cow disease, which can occur all the year round and is generally sporadic or small-scale explosive epidemic.

Type 2: the incubation period of cattle failure is generally 2-5 days. According to the clinical symptoms, cattle failure can be divided into three types: septic type, edematous type and pneumonia type: ① septic type: the body temperature of diseased cattle rises to 41 ℃ ~ 42 ℃, mental fatigue, loss of appetite, rapid heartbeat, often die before finding out the cause and treatment. ② edema type: in addition to the symptoms of elevated body temperature, no eating and no ruminating, the most obvious symptoms are inflammatory edema in the head, neck, throat and other parts, which can also spread to the forechest, tongue and surrounding tissues. Sick cattle often lie on the ground, it is extremely difficult to breathe, and often suffocate to death. ③ pneumonia type: the main manifestations of diseased cattle are elevated body temperature, pleuropneumonia, dyspnea, painful cough, mucous purulent nasal discharge from nostrils, dyspnea, head and neck protruding, mouth-opening breathing, pneumonia type has a long course of disease, often lasting more than a week.

(3) Prevention: in order to prevent the disease of cattle, it is necessary to strengthen the feeding management and improve the resistance. Where cattle failure often occurs, it is necessary to persist in injecting cattle failure vaccine. After confirming the occurrence of bovine abortive disease, the cattle in the village should also be vaccinated urgently to prevent the spread.

4 treatment: diseased cattle can be injected with sulfadiazine sodium intravenously, twice a day for 3 days. While sulfonamides were used in critically ill cattle, the effect of intramuscular injection of penicillin potassium and tetracycline combined with glucose injection was also better. In addition, there are a large number of Pasteurella multocida in the excreta such as bedding grass and feces of diseased cattle, which can only be used after accumulation and fermentation. The sick cattle barn and its surrounding environment should be disinfected with lime water or 3% Lysol solution. Sick cattle and dead bodies must be slaughtered or disposed of under the principle of preventing the spread of bacteria, the internal organs are deeply buried, the cowhide can be sold after soaking in disinfectant, and the beef can only be eaten after being cut into small pieces and cooked at high temperature.
