How can gilts be vaccinated properly and thoroughly?
1. Development and importance of good immunity in gilts. After a pig receives its first vaccine injection, corresponding antibodies will be produced after a certain period of time. At this point, the antibody titer is low and the duration of maintenance is short, and it does not yet have the ability to resist pathogen invasion, but it lays the foundation for establishing effective immunity later, so this immunization is called basic immunization. If the same vaccine is administered again within a certain period afterward, it can induce a recall response of memory cells produced after the first vaccination, which can rapidly produce antibodies with high titer and longer duration in a short time.
