| 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... |

| 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. Data on digital dermatitis were collected during the second phase as Federal or state Veterinary Medical Officers (VMO's) or Animal Health Technicians (AHT's) contacted producers from February 20 through May 24, 1996 to complete a questionnaire.

| The study uses primary data collected from a survey conducted in Georgia to analyze consumer preferences for testing and certification of fresh produce and consumers' willingness to pay for fresh produce that is certified as free of pesticide residues (FPR). An ordered probit model was estimated to identify the impacts of various exogenous variables on the probability of consumers' willingness to pay for a number of alternative price premiums. The results indicate that consumers' willingness to pay differs with respect to a number of factors. The study concludes that most of the consumers recommend testing and certification, but they oppose large price markups for certified-FPR fresh produce. |

| Assessing the impacts of livestock disease on productivity is enhanced when the management abilities of producers are taken into consideration. One method of doing this is to develop a management index of several production/marketing practices using correspondence analysis which can combine several practices into a few variables. Also, through correspondence analysis herds can be divided into better managed and more poorly managed herds to test the association of management on herd health, productivity, and profitability. |

| Avian influenza disease outbreaks in both Canada and the United States resulted in the depopulation of several million birds. Both countries have laws and regulations stating that owners will receive indemnity from the government to compensate for assets taken or destroyed. Government economists from both countries were charged with the task of determining value upon which indemnity was based. This paper explores the process used to determine value in an industry where market prices are not always observable. |

| 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. This report contains demographic changes of the U.S. and world dairy industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS), Census of Agriculture, and Foreign Agriculture Service. Results of two NAHMS national studies overview changes in the U.S. dairy industry in the 5-year period of 1991 to 1996. The 1991 National Dairy Heifer Evaluation Project included herds of 30 or more milk cows and heifer-rearing operations in 28 states representing 83 percent of U.S. milk cows. NAHMS Dairy '96 described dairy production for operations... |

| 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 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... |

| 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... |
