The Department of Agriculture's National Animal Health Monitoring System is embarking on two studies of livestock health and management—Swine 2006 and Dairy 2007.

Swine 2006 will be NAHMS' fourth study of the U.S. swine industry. The 1990 National Swine Survey focused on health and health management of farrowing sows and pre-weaned piglets. Swine '95 gathered information for more than 90 percent of the U.S. swine herd, focusing on the grower/finisher phase of production. Swine 2000 provided data on nearly 94 percent of the U.S. swine herd on operations with 100 or more pigs.

Swine 2006 will encompass producers in Arkansas, Colorado, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Carolina, Pennsylvania, Ohio, Oklahoma, South Dakota, Texas, and Wisconsin. Objectives of the study include the following:


  • Describing swine management practices during the gestation, farrowing, nursery, and grower/finisher phases of production
  • Determining the prevalence and risk factors for a variety of pathogens in nursery and grower/finisher pigs
  • Examining vaccination and antimicrobial-use practices
  • Determining the prevalence of nonambulatory swine and risk factors responsible for nonambulatory swine
  • Identifying production practices that reduce nutrient content in manure
  • Providing an overview of changes in U.S. swine management and health from 1990 through 2006

Participation in Swine 2006 is voluntary and confidential. Representatives of the National Agricultural Statistics Service will contact a random sample of as many as 5,000 producers to schedule interviews from July 1-Aug. 15. Veterinary medical officers will visit participating producers twice to administer follow-up questionnaires and collect biological/environmental samples. Officers will make the first visit between Sept. 5 and Nov. 17 and the second visit between Dec. 4, 2006, and Feb. 28, 2007.

Producers participating in Swine 2006 will receive test results for porcine reproductive and respiratory syndrome, swine influenza, and Salmonella infection.

The USDA also is seeking input from the dairy industry in developing the Dairy 2007 study, which follows Dairy 2002 and Dairy 1996. A survey to help establish the study's objectives is online at

The Dairy 2007 study will take place between Dec. 29, 2006, and Sept. 30, 2007. Currently, the study encompasses producers in 21 dairy states representing more than 80 percent of U.S. dairy cows and operations.
