Porcine reproductive and respiratory syndrome virus causes significant economic losses in the U.S. — approximately $1.2 billion annually — due to reproductive failure, abortion and high pre-weaning mortality among piglets. Thirty percent of the U.S. breeding herd experiences annual PRRSV outbreaks. A farm’s positive stable status is confirmed by sampling serum from piglets or using processing fluids.

NextGen Biosecurity: A podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting.”

In this episode of At The Meeting, Dr. Scott Dee from Pipestone Veterinary Services shares the latest progress and ongoing challenges in eliminating PRRS in the U.S. swine industry. He breaks down key advancements in biosecurity, from genetic strategies and transport protocols to the role of feed in viral transmission. With decades of research behind him, Dr. Dee explains how the industry is working toward lowering PRRS incidence and strengthening disease elimination nationwide.
