摘要

Commercial swine production in He USA has experienced the challenges of porcine reproductive and respiratory syndrome (PRRS) virus and its disruptive effect upon efficient swine production systems since 19897. Currently, sow herds greater than 1000 females per site have continued to report unstablized reproductive performance. This pilot study utilizes the PRRS modified SN test to access status and identify "at risk" population of 1000 females or greater per site. Once "at risk" populations were identified and third trimester reproductive failure occurred, phase II vaccination with PRRomiSe~R (killed virus PRRS vaccine from Bayer Corporation) was implemented. PRRS modified SN test response was evaluated in serial testings comparing identified populations with vaccinates. This study is a continuing investigation of previously identified herd in pilot study.
