WASHINGTON, Dec 20, 2001 - Representatives from the Missouri Agricultural Statistics Service will visit area dairies in January to conduct the initial survey for Dairy 2002, a national study of health and health management practices at U.S. dairies.

Conducted by the USDA's National Animal Health Monitoring System (NAHMS), Dairy 2002 is a continuation of studies that address priority issues of the U.S. dairy industry. Preliminary data will be published by NAHMS in August 2002.

Data collectors from USDA's National Agricultural Statistics Service (NASS) will begin the study by contacting about 4,000 dairy producers in 21 states, 168 of which are Missouri producers included in thenational sample. The 21 states represent 83 percent of U.S. dairy herds and 85 percent of U.S. dairy cows. The data collected is summarized and used in regional and national estimates.

Objectives of the study serve to:

  1. Describe management strategies that prevent or reduce the prevalence of Johne's Disease, and identify how these strategies have changed since 1996.

  2. Evaluate management factors associated with key food safety pathogens in U.S. dairy cattle.

  3. Describe the level of understanding and preparedness of U.S. dairy producers to respond to threats of foreign animal diseases.

  4. Describe biosecurity practices and trends on U.S. dairy operations.

  5. Describe baseline dairy cattle health and management practices used on U.S. dairies and the changes in these practices since 1996.

  6. Describe animal waste handling systems used on U.S. dairies.

  7. Describe U.S. dairy producers' attitudes towards, and uses of, animal identification.

In 1991, NAHMS conducted the Dairy Heifer Evaluation Project (DHEP), leading to baseline information on heifer health, illnesses and management practices, and prevalence estimates for Cryptospordium, Eschericia coli 0157:H7 and Salmonella.

The NAHMS' Dairy '96 study built on the DHEP. Objectives of the Dairy '96 study included acquiring national prevalence estimates of Mycobacterium paratuberculosis (Johne's disease), bovine leukosis virus, and fecal shedding of E.coli 0157 and Salmonella in adult dairy cows.

Baseline dairy cattle health and management practices were also studied to examine changes since the DHEP. Levels of participation in quality assurance programs, the incidence of digital dermatitis, and a profile of animal waste handling systems used on U.S. dairy operations were also examined. The Dairy 2002 study will continue to address these important issues. Selected producers may choose to receive an additional contact by a Veterinary Medical Officer from the Animal and Plant Health Inspection Service: Veterinary Services (APHIS:VS), who will explain the second phase of the study.

Participation in the Dairy 2002 study is strictly voluntary. NAHMS data and operations where the data were collected are always confidential and not included in national databases.
