Testimonial of a Producer

"Our farm is a 2000-sow farrow-to-finish farm located in southern Minnesota. Our farm utilizes internal gilt multiplication, off-site finishing, and an on-site feed mill. The farm had been PRRS-positive but stable since 2002.

In late October 2005, weaned piglets began showing symptoms of PRRS, including a significant number of dead and unthrifty nursery pigs.

In January 2006, clinical signs of PRRS began surfacing in the sow unit, including abortions and unthrifty piglets. Weaned piglets were diagnosed positive for 1-8-4 strain of PRRS. Following the positive diagnosis, MJPRRS killed PRRS vaccine was administered in multi-doses to gilts and gestating sows with no negative effect.

Within two weeks of receiving MJPRRS vaccine, sow abortions all but ended. The sows started to farrow healthy, normal pigs that tested PCR-negative for PRRS about a week later. Since adding MJPRRS vaccine to our units’ PRRS-management strategy, the death loss and quality of nursery pigs have also significantly improved."
