Less Invasive Sampling Methods for PRRSV Detection in Exposed Gilts

Today, we are sharing a very recent publication from Dr. Mariana Kikuti in collaboration with the MSHMP team. Their project looked at the sensitivity of blood-soaked filter papers, blood-soaked swabs, oral swabs and tonsil oral scrubbings when compared to serum samples to detect PRRSV.

Swine & U: Springtime manure application is just around the corner

By Diane DeWitte, UMN Extension swine educator for The LAND

Maybe your manure plan involves fall application, but as the soils thaw and the tiles begin to run, it’s a good idea to review a few environmental protection habits which will help keep nutrients where they belong.

University of Minnesota Extension provides good resources for nutrient application calculation and groundwater and shoreland protection at its manure management website. Extension manure management specialist, Melissa Wilson, and manure management crops educator Chryseis Modderman provide the latest best management practices for manure application in our Land of Ten Thousand Lakes and Nine Million Pigs.

Immune Response of Pigs Vaccinated Against Proliferative Enteropathy and Co-Infected with Lawsonia intracellularis and Brachyspira hyodysenteriae

Today, we are sharing a recent publication from Dr. Vannucci lab in the Veterinary Diagnostic Laboratory at the University of Minnesota. This project evaluated the pig’s response to a co-infection with Lawsonia intracellularis and Brachyspira hyodysenteriae after receiving an ileitis vaccine. The full manuscript is available in open access on the journal website.
