Vaccines effective in controlling PRRS in nursery

摘要

A RECENTLY completed three-year study on vaccinating nursery pigs for porcine reproductive and respiratory syndrome (PRRS) in a large commercial swine system showed that vaccination can significantly reduce mortality and improve pig performance in groups of pigs in PRRS-positive and mixed PRRS status nurseries. According to research study coordinator Dr. John Waddell with the Sutton Veterinary Clinic in Sutton, Neb., the results help answer one of the major questions producers have about the effectiveness of vaccinating nursery pigs for PRRS.
