Pigs that are resistant to PRRSv developed at University of Missouri

Porcine Reproductive and Respiratory Syndrome (PRRS) virus was first detected in the U.S. in 1987. Pigs that contract the disease have extreme difficulty reproducing, don’t gain weight and have a high mortality rate. The disease costs North American farmers more than $660 million annually. Now, a team of researchers from the University of Missouri, Kansas State University, and Genus plc have bred pigs that are not harmed by the disease.
