Date Funded: 2004
Amount: $4.4 million
Duration: 3 years*
Objective: Control and eliminate PRRS disease in swine.
Why? Each year, PRRS costs the United States $560 million by causing reproductive failure in adult females and deadly pneumonia in nursing pigs. The disease first appeared in the United States in 1986 and spreads easily among herds. PRRS has appeared in all major swine producing areas of the United States and throughout the world.
Impact: Research provided data to assess airborne transmission of the disease and identified air filtration as a way to control it, thereby reducing the need for vaccines. The National Pork Board incorporated project findings into their successful education and outreach network to more that 50,000 producers. Regional on-farm PRRS elimination trials are now underway.
