Prevention and treatment of common blight in cattle after flood

It is hot, rainy and flooded in summer, which is the season with high incidence of bovine epidemic disease. Therefore, attention must be paid to the prevention and control of cattle susceptible diseases in this period. Anthrax

This is an acute zoonotic disease, and cattle are the most susceptible. Blood-sucking insects often occur when they are active in the rainy season and after flooding. The disease is characterized by sudden high fever, coma, purple conjunctiva, trembling all over the body, molars, spasm, natural pore bleeding and other symptoms. Dead bovine body stiffness is incomplete, blood does not coagulate, showing coal tar color, subcutaneous, subserous tissue bleeding, red peptone, splenomegaly.

Prevention and control measures: after being identified as anthrax, vaccinate uninfected cattle as soon as possible, using 1 ml of non-toxic anthrax spore vaccine and 0.5 ml of calves. The infected cattle were isolated as early as possible and treated with antiserum and penicillin at the same time. Each cow was injected with 100,300ml antiserum. Penicillin is injected three times a day, each time 1.6 million IU, until it is cured. All corpses and faeces are burned, and contaminated barns, floors, appliances, etc., are disinfected every 2 hours with 20% bleach solution or 10% caustic soda water for 3 consecutive times. The contaminated land should be uprooted 15 cm thick and buried deep. Prevention and control personnel should pay attention to self-protection and prevent infection.

Bovine necrotic bacilli

This is a chronic infectious disease caused by necrotic bacilli. The diseased cattle showed necrosis of skin, subcutaneous tissue and digestive tract mucosa. Hoof rot is common in adult cattle. Calves are infected with necrotic bacilli when they eat feed with prickles and are infected with necrotic bacilli when changing their teeth, showing necrotizing stomatitis and often causing bronchitis. Calves are also prone to necrotizing enteritis, with purulent blood in the feces when diarrhea is serious.

Prevention and treatment measures: usually should do a good hoof protection, to prevent trauma, trauma should be dealt with in time. Strengthen feeding management and do not feed forage grass with hard or prickly thorns. Ditches should be dug outside the cattle farm and barn to ensure smooth drainage. Instead of grazing on low-lying, moist grasslands, the barn should be built in high and dry places to keep the barn clean and dry. The barn should be sterilized with 10% lime milk or 3%-5% Lysol solution. Remove 15cm thick from the surface of the soil and replace the new soil. The cattle suffering from foot rot were mainly treated locally, first rinsed with potassium permanganate solution or 3% hydrogen peroxide, then mixed with 1 part of formalin and 4 parts of pine distillate oil and smeared. Systemic treatment can use tetracycline, oxytetracycline and so on. For the treatment of necrotizing stomatitis in calves, the pseudomembrane should be removed first, rinsed with 1% potassium permanganate solution, and coated with iodoglycerin twice a day until cured. Bovine foot-and-mouth disease

Sick cattle have fever (40 ℃ ~ 41 ℃), drooling, blisters on mouth, tongue and lips, and then festering, with symptoms of pharyngitis and gastroenteritis, red and swollen crowns and toes, blisters and ulcers, and sometimes blisters on the breast, which can also cause mastitis. Calves have symptoms of myocarditis and hemorrhagic enteritis with high mortality.

Prevention and control measures: cattle with foot-and-mouth disease should be reported immediately, the epidemic area should be sealed off, and the diseased cattle and the same herd of cattle should be isolated and slaughtered. Contaminated barns, sites, utensils, etc., are strictly sterilized with 1%-2% caustic soda water or 10% lime milk. Strengthen nursing care for sick cattle and make them drink more water. For diseased cattle that can eat grass, thin rice soup can be fed. After cleaning the bovine oral disease department with vinegar and water, disinfect the ulcer surface with 1%-2% alum water. Rinse the hooves with 3% Lysol solution, then apply iodine glycerin and bandage them. When there are blisters on the breast, rinse with soapy water and apply penicillin ointment. The cattle with malignant disease can be treated with sodium caffeine and glucose.
