An acute infectious disease of sheep is characterized by sudden onset, short course of disease, true gastro-intestinal bleeding and inflammatory lesions.
Experts solve the disease. (1) Pathogens: The pathogen of this disease is Clostridium septicum, a Gram-positive anaerobic bacillus. The bacteria can produce multiple types of mycin. Spores can be produced both inside and outside the animal and do not form decidua. It is generally necessary to use strong disinfectants such as 20% bleach, 3-5% sodium hydroxide to disinfect.
(2) Epidemic characteristics: Most of the affected sheep are sheep with better nutrition from 6 to 18 months of age, and fewer goats. Occur in the spring and fall season, the sheep eat contaminated feed or drinking water, when the outside of the existence of bad incentives, such as sudden changes in climate, rain, internal parasites, etc. can induce this disease. Disseminated mainly, low incidence and high mortality.
(3) symptoms: a, the most acute type. The incubation period is not yet obvious. The diseased sheep suddenly stopped feeding and ruminating. They had molars, abdominal pain, and cramps. Their limbs were separated. Their hindquarters wobbled, their breathing was difficult, and their mouths and noses flowed out of foamy liquids. He fell to the ground and his limbs were swimming and died 2-6 hours later. b. Acute type. At the beginning of the illness, she was in a state of lack of energy, loss of appetite, unstable walking, difficulty in defecation, lying in the ground, abdominal distension, shortness of breath, conjunctival hyperemia, and turbulent flow. Faeces with inflammatory products or mucous membranes, dark green. When the temperature rises above 40°C, breathing is difficult and it soon dies.
(4) necropsy lesions: necropsy lesions can be seen in the dead sheep, stomach bleeding inflammatory changes, the bottom of the stomach and the pylorus near the mucosa, often slightly lower than the surrounding normal mucosa bleeding and necrosis area. Submucosal tissue edema, thoracic, abdominal cavity and pericardial effusion, hemorrhage in the heart's internal and external membrane and intestine, gallbladder more swelling.
Expert treatment. 1 Prevention: Because of the short course of the disease, it is often too late to treat. Therefore, we must strengthen the usual preventive measures. When the disease occurs on pastures, the diseased sheep will be isolated and trials for symptomatic treatment will be conducted for cases with longer duration. When the disease occurs seriously, the transfer of pastureland can receive the effect of reducing the morbidity. Therefore, all non-pathological sheep should be transferred to Gaozao area for grazing, strengthen feeding and management, prevent colds and colds, and avoid sheep to feed on frozen feed. Do not go out too early in the morning. Simultaneous vaccination with bacterins. In the areas where the disease is common, regular injections of "combined sheep epidemic disease, delirium, and enterotoxemia" or "rapid epidemic of sheep, delirium, enterotoxemia, lamb dysentery, and epidemic disease" may be performed every year. .
2 treatment: sick sheep are often too late to cure and die. Slightly longer diseased sheep can be treated. a, penicillin, intramuscular injection, 80-1.6 million units each time, 2 times a day; b, sulfadiazine, gavage, per kilogram of body weight 5-6 grams, once every 3-4 times; c, 10-20% Lime milk, gavage, 5-100 ml each time, once every 1-2 times; d, compound sulfadiazine sodium injection, intramuscular injection, 0.015-0.02 g per kilogram body weight (measured by sulfadiazine), 2 daily Times.
