Prevention and control of harmful epidemic disease of raising deer

The No. 5 disease spreads rapidly and does serious harm. The method of prevention is to inject bovine foot-and-mouth disease type O vaccine, but it is easy to cause miscarriage after vaccination of female deer, and the recessive infected deer are easy to promote the outbreak of the disease, so if a herd of deer already has the disease, injecting this vaccine should be cautious. Its treatment is the use of broad-spectrum antibiotics, antiviral drugs, such as "Luyanting", "epidemic enemy injection", supplemented by comprehensive treatment measures, such as infusion, cardiotonic, detoxification, can generally be cured. Once the case is found, the sick deer should be isolated in time, and the enclosure, pool and forage trough should be disinfected with strong disinfectant, and outsiders are prohibited from entering the breeding area to prevent infection caused by virus.

Enterotoxemia is caused by Clostridium welchii, which is a conditional pathogen. The disease mostly occurs in deer with good body condition, and is characterized by systemic toxemia, severe diarrhea, kidney weakness and severe gastrointestinal bleeding. Mostly sporadic, occasionally see local epidemic, can occur all the year round, the north is more common in the spring and autumn season, sudden changes in the weather, sudden change of green feed or a large number of concentrate feed, are easy to induce the disease. The course of the disease is urgent, the mortality rate is high, some see blood-like stool, some do not see any obvious symptoms and suddenly fall to the ground and die. The effect of drug treatment is not good. Can be intramuscular injection of Clostridium welchii inactivated vaccine twice a year, 5 ml each time for prevention. Protective immunity could be produced 15 days after vaccination and lasted for 6 months.

Tuberculosis has no therapeutic value, the only feasible thing is to strengthen epidemic prevention and active immunity, regular disinfection of enclosures, regular quarantine of tuberculosis patients, and isolation of diseased deer. The young deer were vaccinated with BCG within 24 hours after birth, and once again at 12 months and 24 months respectively, while the adult deer were vaccinated continuously for 2 years, once a year, and the immune protection rate was more than 80%. The effect of purifying the disease can be achieved.
