Can sows continue to reproduce after being vaccinated with parvovirus vaccine?

The influence of sow parvovirus infection on fetus is different in different periods. If sows are infected with parvovirus before mating, the fetal mortality rate is extremely high, which is basically nest death. If the sow is infected with parvovirus during pregnancy, the fetus may still be alive, but these fetuses are definitely carriers of parvovirus and will become a new source of infection. Parvovirus is highly contagious, and feed and water are the transmission channels.

When sows are bred for the first time, it is best to complete two vaccinations 20 days before breeding, with an interval of 20 days. Because the time for pigs to produce antibodies after inoculation is generally 15 days, it is more appropriate to do it in advance. Sows have been immunized for three consecutive births, and there is basically no need to do it in the future. If conditions are limited, you can also have two children in a row.
