Research Spotlight - Recent study pinpoints opportunities to better control swine flu

Reprinted as posted on Swine in Minnesota blog June 27, 2023. New research led by researchers at the University of Minnesota College of Veterinary Medicine (CVM) reveals that farmworkers vaccinating and weaning 3-week-old piglets can indirectly and significantly contribute to the spread of the influenza A virus (IAV) on swine farms. This information can help pig producers target biosecurity measures more strategically, curbing swine flu transmission and enhancing swine production outcomes. Continue reading the blog post.

At the Meeting podcast: Market lows causing concern

The At the Meeting, Honoring Dr. Bob Morrison podcast featured Dr. Steve Meyer, Lead Economist for Partners for Production Agriculture on the May 7 episode. Dr Steve Meyer joined Dr. Montserrat Torremorell (College of Veterinary Medicine, University of Minnesota), Dr. Gordon Spronk (Pipestone Veterinary Services) and Dr. Tom Wetzell (Swine Veterinary Consultant) to discuss the outlook for current low pig prices.

Swine & U column: Pig show season & health

By Diane DeWitte, UMN Extension Swine EducatorOriginally printed in The LAND - as the May 12 2023 Swine & U Column My recent work has focused on disease preparedness and pig farm biosecurity, and it always comes to mind when I’m attending livestock shows. Of primary importance is that exhibitors return to their animals at home without bringing along a disease. For this reason, the messages of meticulous biosecurity and careful monitoring of animals’ health are integral parts of exhibitor education. Winter’s finally finished, field work is in full swing, and the livestock exhibition season has begun. Like most Minnesota agriculturalists, I enjoy the summer’s county fairs and their animals, and, of course, the ultimate competition exhibited at the Minnesota State Fair’s youth and open-class swine shows. It’s terrific to see so many folks who’ve worked hard to bring the best pigs in the Midwest to compete in classes with optimum quality peers. My recent work has focused on disea

Biosecurity and rules & regulations of exhibiting livestock in Minnesota

It is fair season in Minnesota, which means exhibitors and pigs are traveling to various county fairs across the state, jackpot shows and to the Minnesota State Fair. Also with the pork industry focused on keeping African Swine Fever (ASF) from entering the U.S., it is a good time to remind exhibitors about the importance of biosecurity as well as zoonotic diseases. The Pork Checkoff has several show pig resources . For a previous MN State Fair, Diane DeWitte and Sarah Schieck Boelke, both UMN swine Extension educators wrote fact sheets focusing on biosecurity in regards to ASF and PRRS . These fact sheets are still relevant. Do you know the livestock exhibiting rules and regulations for Minnesota? If not, brush up before you load up for the show. Having your animals prepared to exhibit will make your check-in process at the show go smoothly. Read MN Board of Animal Health’s Livestock Exhibition Handbook for all the rule and regulations you need to know.
