This report analyzes the feed mill operations of over 200 farm supply and marketing cooperatives. They were surveyed about their 2004 feed mill ownership, production, type of feed produced, method of sales, and feed form. The cooperatives were also asked what animal types they produced feed for and how the feed was sold. Questions asked were similar to ones used in 1984, 1975, 1969, and 1959 surveys. The data was also sorted into 10 standard U.S. farm production regions and 7 feed mill sizes.
