Linhares: Digging deeper into PRRS outbreak management
Porcine reproductive and respiratory syndrome (PRRS) has challenged producers and swine veterinarians for decades. During that time, outbreak management and strategies have evolved along with the virus.
“If you ask 20 different people how they are managing PRRS breaks, you may get 20 different answers,” Daniel Linhares, DVM, Iowa State University, told Pig Health Today. “People are still trying different things to succeed in their PRRS management program.”
Krantz: Prioritize people to improve pre-wean mortality
Today’s sow farms are highly efficient production systems, yet pre-weaning mortality can remain a challenge. “Pre-wean mortality is sometimes less about the pigs than it is the folks taking care of pigs,” Seth Krantz, DVM, Tosh Farms, told Pig Health Today. “We have a lot of opportunity in how we manage, develop and motivate our people…that’s really the key component of lowering pre-wean mortality.”
AgView: Contact tracing for ASF and much more
African swine fever (ASF) has spread like a slow burn across the globe since the 2007 identification in the Republic of Georgia. It moved into the EU, and by 2018, surfaced in China then continued across Asia. In 2021, for the first time in 40 years, ASF was discovered in the Dominican Republic.
“Put simply, the global status of ASF is that it’s here and it’s here to stay, unfortunately,” Patrick Webb, DVM, director of swine health with the National Pork Board (NPB), told Pig Health Today.
Canada develops plan to market hogs during ASF outbreak
Efforts are underway in Canada to develop an ASF-Free Compartments strategy allowing farms to market hogs in the event of an African swine fever (ASF) outbreak.
Egan Brockhoff, DVM, veterinary counselor with the Canadian Pork Council, discussed plans to work with government veterinary authorities and industry to help high-biosecurity farms participate in an ASF-Free Compartments Program that allows them to continue marketing hogs in the face of foreign animal disease. He hopes the US will consider following a similar plan.
VanderWaal: Expect to see new PRRS sublineages emerge
US pig producers know that many different strains of porcine reproductive and respiratory syndrome (PRRS) exist, and that immunological cross-protection amongst different strains can be variable. However, the continual emergence of new sub-lineages continues to destabilize progress towards PRRS control, said Kim VanderWaal, PhD, associate professor at the University of Minnesota.
Mycoplasma hyopneumoniae elimination becomes possible
Over the past two decades, the swine industry learned how to eliminate Mycoplasma hyopneumoniae (Mhp) from herds without depopulation/repopulation, according to Paul Yeske, DVM, Swine Vet Center, St. Peter, Minnesota. Yeske has been at the forefront of the efforts to eliminate the respiratory disease for clients.
