Combining sow herd stabilization and nursery PRRS virus control methods to achieve improved nursery performance

Porcine Reproductive and Respiratory Syndrome Virus (PRRSv) is capable of causing severely negative biological and economic impact in nursery pigs. A recent analysis suggests a negative impact of US$3.35-$9.12/pig during the nursery phase. 1 Nursery depopulation and PRRS modified live virus (MLV) vaccination of pigs are effective tools to minimize the clinical and economic impact of PRRSv infection.2,3 The objective of this study was to evaluate the impact of sow herd stabilization, nursery dep
