The effect of vaccination of sows with a PRRSV inactivated vaccine on litter characteristics in a farm suffering from endemic PRRS
Proceedings of the 18th IPVS Congress, Hamburg, Germany, 2004 - Volume 1:146
This study was carried out in a 1000-sow, farrow-to-finish, PRRSV-infected pig farm in which all gilts and sows were vaccinated with Progressis® (Merial). Litter size and characteristics at birth and at weaning were recorded before and after the vaccination period. Unlike modified live vaccines (MLV), Progressis® (inactivated vaccine) was shown not to have negative effects on the health of sows and gilts even when administered during gestation. In addition, vaccination with Progressis® led to a significant increase in the litter size and litter performance, as a result of improved health status and body conditions of piglets.
