| The NAHMS Beef '97 Study was designed to provide both participants and the industry with information on the nation's cow-calf population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically-valid sample yielding 2,713 producers from 23 states. The 23-state target population represented 85.7 percent of U.S. beef cows on January 1, 1997, and 77.6 percent of U.S. beef operations. NASS enumerators collected data for this report via a questionnaire administered on-farm from December 30, 1996, through February 3, 1997. Contact For This Paper: David Dargatz |

| 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.
