(2) the epidemic prevention system is not strict. Some epidemic prevention workers and pig breeders do not carry out immunization for fear of death caused by the reaction of piglets after vaccination, resulting in a decrease in the epidemic prevention density of pigs.

The attenuated strain of swine origin, developed in China, was attenuated by cell passage, and the diarrhea incidence of piglets born by immunized sows could be reduced by more than 60%. 2. Fire fighting vaccine. Developed in China, the vaccine immunizes piglets with a protection rate of more than 90 percent. Second, vesicular disease immunization methods developed in China, including attenuated live vaccine and inactivated vaccine.

How to do well the immunity of reserve pigs
1. The production and importance of good immunity of reserve pigs after the first injection of vaccine to pigs, the corresponding antibodies will be produced after a certain period of time, at this time, the antibody titer is low, the maintenance time is short, and they do not have the ability to resist pathogen invasion. but it laid the foundation for the establishment of effective immunity in the future, so it is called basic immunity. Re-inoculation of the same vaccine in a certain period of time can induce the recall response of memory cells after the first vaccination, which can quickly produce high titer and maintenance time in a short period of time.
