Unique herd of U of M Holsteins can help reduce mastitis in dairy cows

For almost 60 years, the University of Minnesota has maintained a one-of-a-kind herd of Holsteins. Scientists have now shown these unique “unselected” Holsteins offer considerable potential to help improve health traits of dairy cows. This includes a greater resistance to mastitis, a common infection in dairy cattle that significantly affects global milk production and can cause major health concerns for afflicted cows.
