| 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... |

| As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. The National Agricultural Statistics Service (NASS) collaborated with USDA:APHIS:VS to select a producer sample that was statistically designed to provide inferences about the nation's cow/calf population. Data for Part V: Quality Assurance Profile were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 1 and January 31, 1994. The average... |

| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. Veterinary Medical Officers (VMO's) and Animal Health Technicians (AHT's) collected data for Part III from 1,219 operations that had 30 or more milk cows on January 1, 1996, from February 20 through May 24, 1996.

| Due to a lack of national information about cull dairy cows, the USDA's National Animal Health Monitoring System (NAHMS) Dairy '96 Study investigated culling management practices. Operations included in the study represented 83.1 percent of U.S. milk cows. Most dairy cows were culled for reasons associated with their inability to profitably produce high-quality milk and calves; reasons for culling were not usually related to ill health or systemic disease. Results showed that almost all cull dairy cows in the US are intended for beef slaughter, as only about 4.4 percent were sent to other dairy operations. Nearly 77 percent of cows intended for beef slaughter were sent to markets, auctions, and sale barns, while 22 percent were sent straight to slaughter... |

| 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... |

This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part III: Beef Cow/Calf Health & Health Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 4 and February 28, 1993. These 18 states represented 70 percent of the U.S. beef cow inventory. Participating producers had five or more beef cows or beef replacement heifers and fifty percent or more of their 1992 calf crop... |

| One objective of the NAHMS Dairy '96 Study was to assess dairy producer awareness of Johne's disease, estimate national and regional herd-level prevalence of Mycobacterium paratuberculosis infection, estimate economic losses due to Johne's disease on dairy operations, and describe use of recommended preventive measures on U.S. dairy operations. Data were collection from U.S. dairy operations with at least 30 milk cows in 20 states representing 79.4 percent of U.S. dairy cows via questionnaires administered to dairy managers and blood samples collected from milk cows by Veterinary Medical Officers and Animal Health Technicians. Sera were tested for antibodies to M. paratuberculosis using a commercially available ELISA. Results showed lack of... |

| 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 Equine '98 Study was designed to provide both participants and the industry with information on the nation's equine population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample such that inferences can be made for all places with equids and for all equids in the participating states. Included in the study were 28 states that accounted for 78.2 percent of the U.S. horses and ponies and 78.0 percent of farms with horses and ponies. NASS interviewers collected data from 2,904 participants via questionnaire from March 16 through April 10, 1998 for Part I. Inventory data from the 133 participating race tracks were included in this report.... |

| 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 National Animal Health Monitoring System (NAHMS) Beef '97 Study collected data on the marketing practices of 2,713 beef cow-calf producers representing 85.7% of all beef cows as of January 1, 1997, in 23 leading cow-calf states. Of the operations included in the study, 67.4% sold steer calves, and 52.1% sold heifer calves for slaughter in the year preceding the study. By number of operations, auction was the most common method of selling steers (84.9% of operations) and private treaty was the second most popular marketing method (10.4% of operations). By number of steers sold, private treaty was the most common marketing method. For operations selling either steer or heifer calves, smaller operations were more likely to use auctions as a marketing... |
