How to prevent and treat recurrent fever in pigs?

Pigs with "high fever sign" generally show persistent high fever (about 41.5 ℃), red skin and bleeding spots, cyanosis on ear tips, conjunctival flush, shortness of breath or cough, loss of appetite, abortion in some sows, autopsy shows brown lesions of different sizes in the lungs, in severe cases, the lesions spread to the whole lung, showing khaki (color like swine fever kidney), lymph nodes swollen, bleeding, and section succulent.

The key to the prevention and treatment of the disease is to take the policy of prevention first, first, to do a good job in isolation, disinfection, quarantine and other measures to prevent the spread of the disease. After discovering the diseased pigs, first of all, for the pig farms with high fever symptoms and positive tests for blue-ear disease, the attenuated vaccine against blue-ear disease must be injected into pigs in time; for those farmers who have not developed blue-ear disease but are under greater threat from blue-ear disease, pigs should be injected with inactivated vaccine; the fluctuation of the disease in some areas is related to the discontinuation of blue-ear disease vaccine. Second, the prevention of atypical classical swine fever must be strengthened, as classical swine fever is an important cause of high mortality in the cases of "high fever", it is necessary to ensure the immune effect of classical swine fever, and the third is to select effective antibiotics to control secondary infection. antibiotics can be selected by drug sensitivity test Fourth, according to the different pathogens of the disease (such as mycoplasma, toxoplasmosis, eperythrozoonosis, etc.), choose symptomatic drugs for prophylactic administration or treatment to reduce the loss caused by the disease; fifth, use some drugs that can increase pig immunity, prophylactic administration or treatment has a certain effect. Sixth, timely elimination of rehabilitation breeding pigs, generally after treatment and rehabilitation of breeding boars and sows, often lead to low litter size, high abortion rate, and the utilization value is affected.
