New Influenza Testing Rule for Dairy Cows Going to Minnesota Fairs

Jun 17, 2024

Dairy cows headed to a county fair this summer will need at an influenza test.

The Minnesota Board of Animal Health now requires a negative test for the H5N1 virus before a lactating dairy cow can attend any exhibition for “display or judging.”

The H5N1 virus is common in wild birds and infections have led to the deaths of millions of chickens and turkeys in the past two years.

The virus recently has been found in dairy cattle in several states, including a Minnesota farm earlier this month.

“While H5N1 influenza in dairy cases are still being studied across the country, initial insights show milk and the udders are a hotspot for influenza virus on infected cows, which makes showing lactating dairy at events a higher risk,” said Katie Cornille, senior veterinarian of Cattle Programs at the Board of Animal Health.

Requiring a negative test before an exhibition will reduce the risk, Cornille said.

Any cows that test positive will be quarantined for 30 days. The U.S. Department of Agriculture also has dairy cattle testing requirements in place.

Video: Selling Hay for 40 Years: Fritz Trauttmansdorff, Dunlea Farms

Fritz Trauttmansdorff came to Canada from Austria in 1980, bought a 45-cow dairy farm at Jerseyville, and within two years had more hay than he knew what to do with. He sold the quota in 1986, went debt-free, and built a hay business that has kept some of the same customers for forty years. Today Dunlea Farms runs about 2,500 acres — roughly 600 of it hay, the rest IP soybeans and grain corn — and Fritz makes the case that hay isn't the crop you grow when grain doesn't work. It's the crop that makes the grain work.

"If you grow corn, soybeans and wheat, you're on a three-wheeler. If you put hay in the rotation, you're on a four-wheeler."

WHAT WE COVER • Why the hay market moves independently of the Chicago Board — and what that does for farm-level risk
• The real cost of a mistake: five bushels in grain, versus the whole crop in hay
• Getting a second job out of the same iron — planting tractors that mow all summer, tillage tractors that bale
• How a grain farmer can get hay into the rotation without buying a single piece of hay equipment
• Drilling Timothy in the fall and double-cropping soybeans into it the next June
• What it actually takes to go all-in: roughly 500 acres, good sheds, and a baler you didn't buy used
• Local, regional and international hay markets — and choosing which one you're building for
• Why 40-year customer relationships are the asset, not the equipment
