摘要

As part of the National Animal Health Monitoring System (NAHMS),USDA:APHIS:Veterinary Services conducted a National study of beef production designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. This report is the first release of National information resulting from the Beef Cow/Calf Health and Productivity Audit (CHAPA). Data for Part 1: Beef Cow/Calf Herd Management Practices in the United States were collected from beef producers September 29 through October 9, 1992. The National Agricultural Statistics Service (NASS) collaborated with VS to select a producer sample that was statistically designed to provide inferences about the nation's cow/calf population. NASS telephone interviewers contacted producers in the 48 continental States by computer-assisted telephone interview and asked them a series of questions about management practices and the health of their animals. The 2,539 cow/calf producers that participated represented all U.S. cow/calf operations.
