Última IMPORTANCE OF INCOME IN COW-CALF MANAGEMENT AND PRODUCTIVITY AgEcon Ott, Stephen L.. The USDA's National Animal Health Monitoring System (NAHMS) collected data on management practices and cow-calf herds as a source of family income from a representative sample of cow-calf producers from 23 of the leading cow-calf states. Overall, 2,713 producers with one or more beef cows participated in the NAHMS Beef '97 Study, representing 85.7 percent of the beef cows and 77.6 percent of the beef cow operations in the United States as of January 1997. Producers whose cow-calf herds were the primary source of family income were more productive than those whose herds were a supplemental source of income.

The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992 with the assistance of 1,811 producers from 28 states. Producers included in the study each had herds of 30 or more milk cows, representing 78 percent of the milk cows in the U.S. The average total of cattle and calves on each operation was 169.4. The main breed on 94.9% of operations was Holstein. Slightly over 46 percent of operations stated reproductive problems as the cause of low milk production of cows culled from the herd. Newborn calves were separated from their mothers before nursing on 28.0 percent of operations and less than 12 hours after birth on 39.6 percent of operations. On 64.0...
