The Department of Agriculture's National Animal Health Monitoring System is launching its fourth study of dairy health and health management in the United States.

In January, the USDA's National Agricultural Statistics Service will administer on-site questionnaires to a random selection of dairy producers in 17 states encompassing 79.3 percent of U.S. dairy herds and 82 percent of U.S. dairy cows. The states are California, Idaho, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, New Mexico, New York, Ohio, Pennsylvania, Texas, Vermont, Virginia, Washington, and Wisconsin.

The subsequent phases of NAHMS Dairy 2007 will consist of field visits from Feb. 26-April 30 and May 1-July 31.

The study investigators will do the following:

  • describe trends in dairy cattle health and management practices
  • evaluate management factors relating to cow comfort and removal rates
  • describe dairy calf health and nutrition from birth to weaning and evaluate heifer disease prevention practices
  • estimate the prevalence of herds infected with bovine viral diarrhea virus
  • describe current milking procedures and estimate the prevalence of contagious mastitis pathogens
  • estimate the herd prevalence and costs of Mycobacterium paratuberculosis
  • describe current biosecurity practices and determine producer motivation for implementing or not implementing biosecurity practices
  • determine the prevalence of specific food-safety pathogens and describe antimicrobial resistance patterns

Study participation is voluntary, and data will remain confidential.
