The USDA's National Animal Health Monitoring System (NAHMS) has been conducting benchmark studies of the livestock industries since the late 1980's. Through 2001 there have been studies of swine (n=3), dairy (n=2), beef cow-calf (n=2), beef feedlot (n=2), catfish (n=l), layers (n=l), sheep (n=l) and equine (n=l).
A stratified random sample of feedlot operations with at least 1000 head capacity in the 12 leading cattle feeding states1 was selected for participation in the Feedlot '99 study. Cattle from feedlots with 1000 head or more capacity in these 12 states accounted for 81.9% of fed cattle marketings for 1999. Operators of selected feedlots were contacted for a series personal interviews to collect information on health and management of cattle in their feedlot. In addition, operators were offered the opportunity to participate in activities that required the collection of water, feed or feces.
