Treatment of foot-and-mouth disease in cattle

Bovine foot-and-mouth disease is an acute, febrile and contagious infectious disease caused by foot-and-mouth disease virus. It is characterized by blisters in oral mucosa, breast and hoof. It has the epidemiological characteristics of rapid epidemic, wide spread, acute disease and great harm. The mortality rate of calves is higher, while the others are lower. Let's take a look at the treatment of bovine foot-and-mouth disease.

Symptoms of foot-and-mouth disease in cattle

The incubation period of bovine foot-and-mouth disease is 2-7 days, it can be seen that the body temperature rises by 40-41 ℃, salivating, and blisters soon appear in the lips, gums, tongue, buccal mucosa, soft skin between hoof and toe, and on breast skin. After the blisters break, red rotten spots are formed, and then erosion gradually heals, and ulcers may also occur, forming spots after healing. Diseased cattle salivate a lot, eat less or refuse to eat, and pain in the hoof causes claudication or even shedding of the hoof shell. The general mortality rate in adult cattle is not high, between 1% and 3%, but in calves, the mortality rate is very high due to myocarditis and hemorrhagic enteritis.

Prevention of foot-and-mouth disease in cattle

1. Vaccination: early vaccination should be done conscientiously. When immunizing, we should first find out the virus type of the virus prevalent in the local or adjacent areas at that time, and select attenuated or inactivated vaccine according to the virus type. Rehabilitation serum or high immune serum can be used in epidemic areas and threatened livestock, especially to control the epidemic situation and protect young animals.

2. emergency extermination: if an epidemic has occurred, it should be reported to the relevant departments immediately in accordance with the relevant regulations of our country, and emergency measures should be taken to extinguish it. The government at or above the county level where the disease occurs shall issue a "hexagram lock order" to blockade epidemic spots and epidemic areas, and human and animal exchanges are strictly prohibited. Culling and destroying diseased animals and their fellow animals and eliminating the source of the epidemic. Organize the disinfection work, disinfect the livestock house and the polluted environment at any time and put out the epidemic situation. The virus was isolated and identified, the virus type was determined, and the corresponding vaccine was used to vaccinate the susceptible cattle urgently. 14 days after the death, emergency slaughter or recovery of the last sick cow in the blockade area, the blockade can only be lifted after thorough disinfection.

3. Disinfection in epidemic areas: 2% sodium hydroxide, 2% formalin or 20% Mel 30% hot plant ash water, 5% Mel 10% ammonia, etc., can be used during disinfection.

Treatment of foot-and-mouth disease in cattle

First of all, it is necessary to strengthen nursing care for diseased cattle, such as clean, dry, ventilated and ventilated enclosures, provide soft feed (such as grass, noodle soup, rice, etc.) and clean drinking water, and often disinfect the enclosure, while strengthening nursing care, depending on the location of the disease. give different treatments.

1. Oral treatment: wash the mouth with 0.1% Mel 0.2% potassium permanganate solution, 0.2% formalin, 2% Rue 3% alum or 2% Rue 3% acetic acid or vinegar, and then smear 10% Moe 20% iodoglycerin or 1% Rue 3% copper sulfate on the festering surface. It can also spread ice boron powder, bean noodles and various antibacterial ointments.

2. Hoof treatment: soak the hooves with 3% Lysol, 1% formalin or 3% 5% CuSO4 solution. It can also be washed with water and coated with antibacterial ointment or 20% iodoglycerin, then bandaged. Note that it is best not to wash your hooves too much, in case dampness interferes with recovery.

3, breast treatment: when milking, routine disinfection, warm water cleaning, and then coated with penicillin ointment or sulfonamide ointment, milking, the action should be light.

4. Concurrent treatment: when cattle have complications or malignant foot-and-mouth disease, cardiotonic agents, nutritional supplements and antibiotics can be used in addition to local symptomatic treatment. If necessary, glucose or saline plus antibiotic infusion is used, or some soju is added to drinking water. Whole blood or serum of cattle more than 20 days after the disease can also be injected according to 2 ml per kilogram of body weight.
