Changes of Antibody to Porcine Circovirus Type 2
There were two peaks of antibodies against porcine circovirus, one was maternal antibody at 1~2 weeks of age, the other was maternal antibody at 8~10 weeks of age, which was caused by circovirus infection, and then the antibody level decreased to undetectable at the stage of big pig, which also indicated that the virus infection was slight at this stage. Porcine circovirus infection is very harmful to pigs. The period of low health level of pigs coincides with circovirus infection in time. This is our strict prevention against immune failure and secondary infection.

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.
