With the increase in the size and quantity of beef cattle, cattle disease has become a problem plagued farmers. This article focuses on several common symptoms of beef cattle disease, diagnosis and treatment and prevention methods, with a view to provide a reference for the majority of farmers.

 

   1 bovine viral diarrhea - mucosal disease

 

    Bovine viral diarrhea - Mucosal disease is an infectious disease caused by a virus. The disease spreads the virus through secretions and excretions, polluting the water and feed. Susceptible cattle mainly by the digestive tract and respiratory infections, fetal calves can be placenta infection.

 

    The diagnosis of the disease need to be virus isolation and serological tests, there is no effective treatment. After the onset of the application of astringent and supplement body fluids, with anti-bacterial drug control secondary infection can reduce the loss, it is best to kill the disease to eliminate the source of infection. In the event of the disease, the sick cattle must be timely isolation or urgent slaughter, to prevent the expansion of infection.

 

    2 hemorrhagic Pasteurellosis

 

    Pasteurellosis is a hemorrhagic infectious disease in a variety of animals caused by Pasteurella multocida. Bovine acute after major sepsis and hemorrhagic inflammation, it is called bovine hemorrhagic septicemia (cattle failure), with high fever, pneumonia or acute gastroenteritis and viscera extensive bleeding as the main feature. The disease is bleeding type, pneumonia type and edema type. Bleeding type can often develop into a swollen type and pneumonia type, the mortality rate of more than 80%.

 

    According to clinical symptoms, pathological changes and exudate smear, with alkaline beauty blue stain microscopic examination, there are two ends of the oval-shaped small bacilli can make a diagnosis, if necessary, bacterial isolation and identification. Should be distinguished from malignant edema, anthrax and gazelle. The cattle were treated with 3% sodium hydroxide, 5% bleach or 10% lime milk. The epidemic area was inoculated once a year with bovine hemorrhagic sepsis aluminum hydroxide vaccine. And pay attention to strengthen the feeding and management, reduce stress response.

 

    3 leptospirosis

 

    Leptospirosis is a natural phytophagous infectious disease caused by a variety of serotypes of leptospira. Sick animals and a variety of carriers of the disease is the main source of the disease. They are through the urine and other ways out of a large number of bacteria.

 

    When the disease to isolate the disease cattle, given to streptomycin, oxytetracycline, chloramphenicol and tetracycline have a certain effect. At the same time with the replenishment of body fluids, and even lost to the whole blood, the effect is better. Prevention and removal of contaminated water, sewage, silt, pasture, feed, stables, stadiums, appliances, etc. to prevent infection and spread; regular vaccination , Enhanced the specific resistance of herd, the vaccine serotype should include the popular serotype; strengthen feeding and management, improve the herd non-specific disease resistance.
