The Midland United Dairy Industry Association (Midland UDIA) was formed in 1971 by farmers in Iowa, Missouri, and eastern Kansas as a regional advertising and promotion organization. It is a member of the United Dairy Industry Association, the umbrella organization for the National Dairy Council and the American Dairy Association. Headquartered at Ankeny (Iowa), this organization inherited most of what were formerly functions of the Iowa State Dairy Association. In 2000 Midland UDIA merged with the American Dairy Association and Dairy Council of the Upper Midwest (Minnesota, North Dakota, and South Dakota) to form the Midwest Dairy Association.
