Milk Source was co-founded in 1999 by UW-Madison graduates Jim Ostrom, John Vosters and Todd Willer — each from multi-generational Wisconsin farm families — and traces its roots back to 1965 when a small 30-cow dairy farm was started in Freedom by John’s parents. Today, MilkSource Genetics is known globally for some of the world’s finest purebred cattle.
Milk Source operates quality dairies in Wisconsin, Michigan and Missouri, producing milk that is used to make cheese, butter and other dairy products. In addition, Milk Source also has a Wisconsin calf farm and a heifer-raising facility. We are leaders in modern sustainable agriculture, finding safe, reliable and expandable technologies that tie economic success with environmental stewardship. Our farms have been pace-setters in the use of technology such as sand recycling, manure separation and underground nutrient pipelines.
As a result of commitments like these, Milk Source was named Dairy Today’s Innovative Dairy Farmer of the Year for 2014, Wisconsin Manufacturers & Commerce’s 2014 Business Friend of the Environment, Wisconsin Family Business Council’s 2015 “Innovation & Sustainability” Award winner, the 2015 Zoetis Diversity and Inclusion Award winner, a 2016 Wisconsin Top Rural Development Initiative Award winner and one of three finalists for the 2014 and 2015 Wisconsin Leopold Conservation Awards.
MilkSource Genetics is also home to three living EX-97 Cows – Blondin Redman Seisme-Red, Musqie Iatola Martha and Weeks Dundee Anika, among numerous other high scored Holsteins, Red & Whites and Jerseys.
