Nadine Houck and her colleagues at the Penn State Dairy Barns milk more than 230 cows twice a day. Each cow can provide nearly 10 gallons of milk daily. The milk provided by Penn State's cows supplies the Berkey Creamery with all of the cream necessary to manufacture ice cream, milk, cheese and more for the Penn State community.
