Designed by architect John Bennes and his colleagues in 1907, construction of the first Dairy Barn was completed in 1909. With a cement foundation and brick columns, the two-story main building measured 50 by 100 feet and the two, single-story adjoining wings measured 46 by 80 feet each. The barn also included a milk room, engine and fuel rooms, and a "concrete basement for the storage of roots." Up to 70 cows (and 9 horses) could be housed in the east wing of the building, and the concrete floors were specially outfitted with traps and drains to allow for easy cleaning.

After a new dairy barn was built in 1937-38, the structure became the Agricultural Utilities Building. Over the next fifty years, it was utilized by several departments (Agricultural Engineering, Horticulture, Computer Science) and the USDA. It was razed in 1989 to make way for the Agricultural and Life Sciences Building. Pillars from the original barn structure are still visible in the basement of the new building.
