Kansas grows more wheat, grinds more wheat into flour, and produces more wheatmiddlings than any other state in the nation. In 1997, Kansas grew a record 506 million bushels of wheat. One-fifth of that wheat production was used to manufacture flour in Kansas. According to the Sosland publication, Grain and Milling Annual 1997, the rated production capacity of Kansas flour mills is 152,440 hundredweights of flour per day. The estimated amount of millfeed produced in Kansas in 1997 was 735,729 tons or 10 % of the total amount produced in the United States. During the wheat milling process, about 70 to 75 % of the grain becomes flour, and the remaining 25 to 30 % is available as wheat by-products largely destined for livestock consumption. These by-products commonly are referred to as millfeed (MF), wheat mill run (WMR), or wheat middlings (WM) with little regard for the various mill streams and proportions that are combined and ultimately constitute the by-product’s final composition. As a consequence of this inconsistent terminology, difficulties are encountered when ascertaining nutritional value and establishing economic worth. The term WM will be used in this publication to collectively describe WMR and MF. USDA production estimates rank WM second to soybean meal as the dominant by
