H5N1 Bird Flu links for Wisconsin Farmers

Apr 10, 2025

Highly pathogenic avian influenza (HPAI) H5N1 is a virus that has traditionally affected birds. Recently, however, it has been confirmed in dairy cattle and detected in other species, including humans. This marks a significant and unprecedented development for the dairy industry.

The emergence of HPAI H5N1 in cattle highlights the urgent need for a One Health approach, which recognizes the close connections between human, animal, and environmental health. As the situation evolves, it’s critical to strengthen biosecurity practices, enhance surveillance efforts, and support research to better understand how the virus spreads and how to manage it.

Because this is a rapidly changing situation, we encourage dairy producers and industry professionals to stay informed. For the most up-to-date and reliable information, follow guidance from the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), the Centers for Disease Control and Prevention (CDC), and the National Milk Producers Federation (NMPF).

Video: Selling Rams & Helping New Farmers Begin

It’s shipping day again at Ewetopia Farms as we sell another Suffolk yearling ram! In today’s episode, we load one of our Suffolk rams onto the trailer as he heads off to his new farm to sire the next generation of lambs.

This particular customer has been buying our rams for over eight years, trusting Ewetopia genetics for their gentle temperaments, strong builds, and proven performance. Back home, we get busy looking after the flock that’s staying behind. With the weather turning wet and chilly, it’s time to put down fresh, clean bedding to keep everyone cozy and comfortable for the season ahead. Later, we welcome a wonderful new family who’s just starting out in sheep farming!

They’ve chosen some of our Suffolk ewe lambs to begin their flock — and we couldn’t be happier to help them take their first steps into raising sheep. Stay tuned for a follow-up episode when we help deliver and settle their new flock at their farm.
