The pigs suffering from "high fever syndrome" generally exhibit high fever (around 41.5°C), persistent redness, bleeding spots, hair blisters, conjunctival flushing, shortness of breath or cough, loss of appetite, and some sows' miscarriages. Anatomy shows that there are brown lesions of different sizes in the lungs. In severe cases, the lesions spread throughout the lungs. The kidneys appear khaki (like the color of pig kidneys), lymph nodes swelling, bleeding, and juicy sections.
The key to prevention and control of the disease is to adopt a policy that focuses on prevention. The first is to isolate, disinfect and quarantine measures to prevent the introduction of this disease. After the diseased pigs are found, first of all, for farms with high fever signs and positive detection of blue ear disease, pigs must be given a vaccine for blue ear disease in a timely manner; for pigs, there is no blue ear disease, but threatened by blue ear disease The farmer should give the pig an inactivated vaccine; the disease condition in some areas is related to the suspension of the blue ear disease vaccine;
Second, it is necessary to strengthen the prevention of atypical swine fever. Because swine fever is an important cause of high mortality in cases of "high fever syndrome," it must be ensured that the swine fever effect is in place.
The third is to use effective antibiotics to control secondary infection. Antibiotics can be selected through drug susceptibility testing;
Fourth, according to the different pathogens of the disease (such as mycoplasma, toxoplasma, erythropoietin, etc.), choose symptomatic drugs for preventive administration or treatment to reduce the loss caused by the disease;
The fifth is to use some drugs that can increase the immune system of the pigs for preventive drug administration or treatment. There is a certain effect. Sixthly, timely recovery of breeding pigs, breeding boars that are treated and recovered, often results in low litter size. The abortion rate is high and the utility value is affected.
