The NAHMS Cattle on Feed Evaluation (COFE) was designed to provide both participants and the industry with information on the nation's feedlot animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid producer sample (3,214 producers) to provide inferences to the nation's feedlot animal population. Included in the study were 13 states that accounted for 85.8 percent of the U.S. cattle-on-feed inventory as of January 1, 1994. State and Federal Veterinary Medical Officers (VMO's) collected data from feedlots of 1,000 head or more capacity through personal interviews from October 3 through December 21, 1994, for Part II.
