In 1995, the National Animal Health Monitoring System (NAHMS) collaborated with the Research and Education Division of the American Sheep Industry Association (ASI) in developing a needs assessment tool to identify the most important health and productivity factors for the sheep industry. In collaboration with the USDA's National Agricultural Statistics Service (NASS), a statistically designed producer sample was selected to provide estimates for the United States sheep population in the 48 contiguous states. The NAHMS/ASI questionnaires were mailed to 19,807 sheep operations in January 1996; data were received and summarized from 5,174 respondents. It was estimated that in the 48 contiguous states, there were 82,040 operations with sheep as of 1995;... |

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.

The National Animal Health Monitoring Systems (NAHMS) Dairy +96 Study of dairy herds in 20 states examined herd management practices that varied between high-producing (top 25%) and low-producing (bottom 25%) U.S. dairy herds. Only 100% Holstein herds were included in the study. Within four size categories (30-99 cows, 100-199 cows, 200-499 cows, 500 or more cows) herds were ranked by milk production per cow. High-producing herds were more likely to use Dairy Herd Improvement Association records or an on-farm computer system than low-producing herds. High-producing herds were also more likely to feed a total mixed ration, use forage test results in balancing feed rations, use bovine somatotropin (bST) and/or systematic prostaglandins, and vaccinate against... |

In 1995 and 1996, prices for weaned calves were at the lowest point for the current cattle market cycle. The National Animal Health Monitoring System (NAHMS) Beef ,97 Study examined the effects of the down market on beef cow-calf herd management practices. Most producers did not alter management practices in response to the down market. Among producers who made changes, costs were cut largely in the area of herd health management. Specific management practices in which costs were cut included decreases in use of vaccinations (7.4% of operations), herd medications (7.7% of operations), individual cow medications (5.0% of operations), and veterinary services (14.1% of operations). Other ways that producers altered management practices in response to the down... |
