Sick pigs suffering from "high fever" generally show high fever (around 41.5 °C), red skin and bleeding spots, blemishes, conjunctival flushing, shortness of breath or cough, loss of appetite, abortion of some sows, The dissection shows that there are brown lesions of different sizes in the lungs. In severe cases, the lesions affect the entire lungs. The kidneys are khaki (like the color of the pig's kidney), the lymph nodes are swollen, bleeding, and the slices are juicy.
The key to preventing and treating this disease is to adopt a prevention-oriented approach.
First, do a good job of isolation, disinfection, quarantine and other measures to prevent the introduction of this disease. After the discovery of sick pigs, first of all, for pig farms with high fever and positive blue ear disease test, pigs must be injected with attenuated vaccine of blue ear disease in time; for pigs, there is no blue ear disease, but the risk of blue ear disease is greater. The farmer should give the pig an inactivated vaccine; the fluctuation of the disease in some areas is related to the withdrawal of the blue ear vaccine;
Second, it is necessary to strengthen the prevention of atypical swine fever, because in the "high fever" cases, swine fever is an important cause of high mortality, it is necessary to ensure that the immune effect of swine fever is in place;
The third is to use effective antibiotics to control secondary infections. Antibiotics can be selected through drug susceptibility testing;
Fourth, according to different pathogens (such as mycoplasma, toxoplasma, erythropoiesis, etc.), use symptomatic drugs for preventive drug delivery or treatment to reduce the damage caused by the disease;
The fifth is to use some drugs that can increase the immunity of pigs for preventive drug administration or treatment, and have certain effects. Sixth, it is timely to eliminate the rehabilitation of breeding pigs, and the breeding boars that are generally treated and rehabilitated often lead to low litter size. The rate of abortion is high and the value of utilization is affected.
