New 3-Year Project with South Korea RDA on Porcine Reproductive & Respiratory Syndrome (PRRS)

May 2014. A cooperative agreement between the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA) and the National Institute of Animal Science (NIAS), Rural Development Administration (RDA) of the Republic of Korea addressed porcine reproductive and respiratory syndrome (PRRS). PRRS is the most costly disease of swine producers worldwide. Based on US PRRS Host genetics Consortium studies of genetic resistance to PRRS virus infection, a region on swine chromosome 4 (SSC4) was associated with resistance to PRRS virus infection. Scientists at the ARS Beltsville Agricultural Research Center cooperated with RDA scientists to determine whether Korean pigs bred for the SSC4 resistance marker will be more resistant to PRRS virus infection and exhibit improved litter (offspring) numbers and health.
