PRRS has challenged producers and swine veterinarians for decades. During that time, outbreak management and strategies have evolved along with the virus.
US pig producers know that many different strains of PRRS exist, but the continual emergence of new sub-lineages continues to destabilize progress towards PRRS control,...
Regular biosecurity checks with a close look at filtration and ventilation systems will help prevent the spread of airborne pathogens like porcine reproductive and...
Eliminating porcine reproductive and respiratory syndrome virus (PRRSV) from pigs might not yet be possible, but monitoring tools could help refine a herd's PRRSV...
The system used to classify breeding herds according to their PRRSV status has long helped swine veterinarians around the world to track the pathogen’s progress.
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...
Nine years of data from the Morrison Swine Health Monitoring Project show farms with air-filtering systems have fewer outbreaks of PRRS than farms without filters.
PRRSV is constantly evolving, resulting in an extremely diverse virus with multiple lineages, but building a better understanding of that genetic diversity is the next...
Newer testing methods for the PRRS virus are not only simpler and less costly than traditional procedures, they are also helping farms more accurately track the virus...
Summer outbreaks of PRRS take 15 weeks longer to stabilize than PRRS outbreaks beginning in the winter, according to data from the Morrison Swine Health Monitoring...
If knowledge is power, being prepared is security. Both are drivers behind the Swine Health Information Center’s (SHIC) program to share information among the...
Collecting aggregate samples of processing fluids during tail docking and castration is proving to be an excellent way to monitor herds for porcine reproductive and...
Several factors go into selecting a site for a pork-production unit, but research shows there are a couple more — specifically, terrain and vegetation — that may...
Collaboration among veterinarians working with different pork producers is one of the great benefits emanating from the Morrison Swine Health Monitoring Project...
Porcine reproductive and respiratory syndrome (PRRS) remains one of the most costly viruses infecting US herds. But an Iowa State University study showed the annual...
Oral-fluid sampling can provide a simple, reliable way to surveil for porcine reproductive and respiratory syndrome virus (PRRSV), Marisa Rotolo, DVM, of Iowa State...
Every year, porcine reproductive and respiratory syndrome (PRRS) infects an estimated 25% to 45% of sow herds in the US, according to Clayton Johnson, DVM, Carthage...
It takes 3 to 4 weeks for pigs to develop immunity against PRRSV after vaccination with a modified-live vaccine, so vaccinating early gives them the time they need to...
Around 50% of pigs weaned today likely are infected with a primary viral pathogen, like porcine reproductive and respiratory syndrome (PRRS) or swine influenza,...
Producers looking for ways to reduce porcine reproductive and respiratory syndrome (PRRS) find positive-pressure ventilation with some modifications works, especially...
