Prevention of porcine erysipelas
(1) eliminate the source of the disease: the pigsty is often disinfected regularly with 10% stone from the milk, at least 2-3 times a year.
(2) eliminating transmission factors: the disease in many pig farms is caused by buying pork from outsources. therefore, self-breeding is the key to prevent porcine erysipelas.
(3) to improve the resistance to pig disease: as long as pigs are properly fed and managed, fed more green feed, exercised properly, padded sheds are raised every day, the health status of pigs is checked every day, and diseased pigs are isolated and treated in time.
(4) prophylactic injection of attenuated vaccine of porcine erysipelas: lyophilized attenuated vaccines of GC42 and G4T _ (10) are mainly used in China, and weanling pigs can be immunized for 6 months after vaccination. GC42 attenuated freeze-dried vaccine, in addition to subcutaneous injection, but also can be taken orally, immunity is more convenient. The triple vaccine (classical swine fever, swine erysipelas, porcine lung disease) produced in China is more popular, which saves not only labor but also time, and the immunization period of classical swine fever is more than 8 months. Porcine erysipelas and porcine lung disease were both 6 months.
(5) the prevention and control measures after the disease: ① found that the diseased pigs immediately blocked the epidemic spot, carried out thorough disinfection, fecal accumulation and fermentation, and quarantined the diseased pigs in time. The carcasses of diseased pigs should be buried deeply after burning by ②, and the contaminated land and appliances should be thoroughly disinfected to prevent the spread of epidemic disease. Where ③ has been infected, the blockade may be lifted on the 8th day after the onset of the last diseased pig. And vigorously carry out strict disinfection once and try our best to eliminate the source of the epidemic. After full-scale disinfection, ④ should also be vaccinated, and before the vaccine produces immunity, attention should be paid to prevention and control, surveillance of the epidemic situation and prevention of recurrence.

Methods for the treatment of leprosy in young pigs

What should be paid attention to when giving pigs a vaccination?
Injecting pigs against epidemic is an unavoidable problem for every pig farmer. If it is used reasonably, it will achieve satisfactory results; otherwise, it will cause undue losses to pig production. 1. The health status of pigs should be checked. Sick pigs can not be vaccinated, if vaccinated to sick pigs, not only can not prevent the disease, but also aggravate the disease of pigs. In addition, when vaccinating pigs, every pig in the herd should be injected and do not miss the injection. 2. It is necessary to accurately grasp the injection time of the vaccine and the immunization period of all kinds of vaccines. All kinds of vaccines start in pigs.
