How to manage herd closure for PRRS elimination
Herd closures to eliminate porcine reproductive and respiratory syndrome (PRRS) are on the increase due in part to the virulent variant identified as PRRS 1-4-4 L1C.
Filtration audits help prepare for PRRS season
Regular biosecurity checks with a close look at filtration and ventilation systems will help prevent the spread of airborne pathogens like PRRS, according to Jeff Feder, DVM, Swine Vet Center, St. Peter, Minnesota.
Common mistakes to avoid during PRRS elimination
Eliminating PRRS virus from a breeding herd is not a simple task, and no herd acts exactly like the next, according to Brad Leuwerke, DVM, with Swine Vet Center, St. Peter, Minnesota.
Antibiotics properly timed during PRRS virus outbreak reduce reproductive failure
PRRS is a viral disease, causing endometrial inflammation leading to abortions, stillborns and mummified fetuses. Ross Kiehne, DVM, with Swine Vet Center, conducted a study to evaluate the use of the injectable antimicrobial Draxxin® (tulathromycin) administered to gestating sows during a PRRS virus outbreak.
Reducing PRRS outbreaks by using air filtration: What you need to know
Jeff Feder, DVM, with Swine Vet Center, has spent 15 years fine-tuning filtration systems in client hog barns. Today, Feder has records to prove air filtration does reduce outbreaks of disease like porcine reproductive and respiratory syndrome.
Is reducing inflammation key to improving PRRS control?
PRRS continues to be a critical concern to the U.S. pork industry. The combined production losses associated with PRRS in breeding and growing-pig herds are estimated at more than $663 million, and that doesn’t include secondary infections.
