Symptoms and treatment of bovine epidemic fever

Beef in China's market is relatively large, cattle is also the main livestock in our country, there is a certain breeding area in all parts of our country. Although raising cattle has a history of thousands of years in our country, and the breeding technology is becoming more and more mature. But cattle still produce all kinds of diseases in their growth. Popular fever is one of them. So what are the symptoms of bovine epidemic fever? How do we treat it? Let's take a look at it with the editor.

1. Epidemiology

Epidemic fever has a strong appeal to all kinds of cattle, and the incidence of epidemic fever is the highest in 4-year-old dairy cattle and yellow cattle. Diseased cattle are the main transmission source of epidemic fever virus. Although the main route of transmission of epidemic fever is not very certain, it is possible to spread germs in the air, mosquitoes and contact with diseased animals. The onset time of epidemic fever is generally concentrated in the season of high temperature and high humidity from July to August. The speed of transmission is so fast that a large number of cattle can get sick in a short period of time. And according to previous data, the epidemic cycle is about once every four years. However, the disease is mostly benign, so the mortality rate is not very high.

2. Symptoms

The incubation period of epidemic fever is about 5 days. In the early stage of the disease, the sick cow shivers, and its body temperature rises rapidly to 40 degrees Celsius. When it rises, the cow will shed tears. Shortness of breath accompanied by groans can lead to emphysema and, in severe cases, asphyxiation. And sick cattle will also lose their appetite, stop ruminating, it is difficult to walk, do not want to move. And can also find subcutaneous emphysema, mouth foam and other phenomena. The pregnant cow had a miscarriage and a stillbirth. However, the mortality rate of epidemic fever is less than 1%. In severe cases, it is also eliminated because some sick cattle are unable to walk with pain in their limbs.

3. Preventive measures

When we breed, we must strengthen the management and do a good job in the disinfection and hygiene of the barn. Cut off the transmission of the virus, because what we know now. The main routes of transmission of epidemic fever are mosquitoes and flies. Therefore, in the process of breeding, we must kill mosquitoes regularly and use pesticides such as trichlorfon to spray the cowshed and surrounding environment comprehensively and evenly to kill the eggs of mosquitoes and flies. And popular heat also has the characteristic of being afraid of acid and is very insensitive to alkali. So we can also use acid agents such as peracetic acid to sprinkle the ground to curb the spread of the virus.

4. Prevention and control methods

It has just been said that strengthening management is the main measure of prevention. If mismanaged, it will increase the mortality rate. The diseased cattle should be isolated from the barn immediately, and then the uninfected cattle should be injected with Dichondra hyperimmune serum and other vaccines to avoid expanding the affected area. When the body temperature of diseased cattle rises, appropriate amount of compound aminopyrine and other agents should be used in the pig house in the muscle. If the disease is more serious, then it is necessary to inject antibiotics and maintain a large dose. If the cattle are short of water because of high fever, then appropriate saline should be used in pig houses. Finally, it is necessary to do a good job of disinfection and vaccinate cattle regularly.

The above is a brief introduction to the symptoms and treatment of bovine epidemic fever. When raising cattle, we should not only pay attention to the prevention and control of epidemic fever, but also colds and foot-and-mouth disease can not be ignored, so we must pay more attention.
