FREESTALL BARN More than 190 dairy cows call the Dairy Center’s freestall barn home. The roomy stalls are bedded with sawdust and routinely cleaned to provide our cows a comfortable lounging area. A spacious bunk offers the cows free-choice of fresh feed. Fans and sprinklers cool the animals in the heat of the summer, while curtains on the sides of the barn protect them from the harsh elements of the Midwestern winter. The herd is a colorful collection of four major dairy cow breeds including Holsteins, Jerseys, Brown Swiss and Ayrshires.
