Characterization of the Fetal Immune Response to PRRS
PRRSV causes abnormal development of immune function. This is believed to allow the virus to persist in carrier animals that remain relatively healthy. Such disregulation of the immune is a common...
Best Management Practices Research in a Watershed with Swine Production Facilities
The South Fork of the Iowa River drains a 215,000-acre watershed in northcentral Iowa dominated by agricultural land uses. There are a number of swine-producing facilities in the area, plus several...
