USDA's National Animal Health Monitoring System Conducts Third National U.S. Small Enterprise Swine Study

In 2021, the U.S. Department of Agriculture’s (USDA) National Animal Health Monitoring System, in collaboration with the USDA’s National Agricultural Statistics Service, conducted its third national study of U.S. small enterprise swine operations. Approximately 5,000 swine operations from 38 states, accounting for about 95 percent of U.S. swine operations with fewer than 1,000 pigs, were asked to participate. Small enterprise swine production is a growing sector of the U.S. swine industry due to its role as a primary supplier of many niche-market products.

Objectives of the study included:

  • Describe current health and production practices on small enterprise operations.
  • Describe trends in swine health and disease management practices on small enterprise swine operations.
  • Characterize movement, mortality, and slaughter channels on small enterprise swine operations.
  • Examine differences in marketing practices and movements on small and large U.S. swine operations.

The results of the study are now available as a dashboard. To go to the report, navigate to and scroll down to the “Swine Studies” button. This will take you to the list of reports and associated materials national swine studies have produced over the years.
