What should be paid attention to when giving pigs a vaccination?
Injecting pigs against epidemic is an unavoidable problem for every household. If 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. The time and duration for which various vaccines begin to produce immunity in pigs are different. For example, classical swine fever vaccine can produce immunity 4 days after injection, the immunity period is one year; porcine erysipelas vaccine produces immunity 14 days after injection, the immunity period is 6 months; porcine pneumonia vaccine produces immunity 14 days after injection, the immunity period is 9 months. Pigs may get sick before and beyond the immunity period of the vaccine. therefore, it is necessary to accurately grasp the injection time of the vaccine and the immunization period of the vaccine, and inject the vaccine into pigs in time.
3. The vaccine should be used correctly. Live vaccines should be stored in a-15 ℃ environment, and should not be used if they are not kept in accordance with the prescribed conditions. The vaccine should be used within the validity period, and those that are not used up on the same day after the validity period and after the preparation of the vaccine can not be used. The use of the vaccine should be injected according to the prescribed amount, otherwise it will affect the epidemic prevention effect. At the same time, do a good job of disinfection when injecting vaccines, such as syringes, needles, tweezers and so on. Insist on changing an injection for a needle and disinfect the injection site with 5% iodine.
In addition, after vaccination, pay attention to observe the intake, activity and defecation of pigs, and check the body temperature of pigs to see if there is any abnormality. The sick pigs with obvious reaction should be treated in time.

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.
