Reproduction in gilts inseminated with PCV2-spiked semen. Protection by gilt vaccination with a sow PCV2 vaccine
PCV2 vaccination of the gilts prior to insemination with PCV2 spiked-semen showed a clear decrease of viral load in the gilts as well as a much lower viral excretion that were compatible with foetus protection.
