Seven Minnesota dairy cattle herds have been confirmed with the H5N1 virus since it was first identified in late March. While avian influenza results in high mortality in poultry operations, State Veterinarian Brian Hoefs said that’s not the case for dairy herds. “That being said, the virus itself certainly does affect production in these animals.” Clinical signs include low appetite and reduced milk production. Hoefs urges farmers to take the virus seriously for the sake of more than just the dairy industry.
