NAHMS Swine 2020
In order to protect the health and safety of producers, data providers and data collectors, the study approach and timelines for the National Animal Health Monitoring System’s Swine 2020 Study may be revised. We are actively exploring alternatives to ensure that this important information is collected while protecting the health of all involved. We will continue to update this page as more information becomes available. Thank you for your understanding.
The NAHMS Swine 2020 study will focus and report on two distinct U.S. swine populations: the large-enterprise segment of the study will take an in-depth look at swine operations with 1,000 or more pigs, and the small-enterprise segment of the study will concentrate on swine operations with fewer than 1,000 pigs.
Both segments of the Swine 2020 study will provide participants, industry, academia, trading partners, and animal-health officials with valuable information on the Nation’s swine population. This information will serve as a basis for education and research related to swine health and management, while providing the industry with new and valuable information regarding trends in the industry.
Summary estimates from the study’s Large Enterprise segment will provide insights on how the majority of U.S. pigs are produced, their health status, and veterinary or biosecurity measures taken to maintain their health.
Summary estimates from the study’s Small Enterprise segment will reflect the recent changes in this more diverse and less traditional part of the U.S. swine industry. Objectives of the Small Enterprise segment include estimating the use of newer husbandry technologies being adopted by smaller U.S. swine operations and providing information on the growing niche-market products these operations produce.
Swine 2020 study materials
NAHMS Swine 2012
As with the four previous NAHMS swine studies, NAHMS Swine 2012 was national in scope, collaborative in nature, and voluntary. Data collected during the study were strictly confidential and used to generate scientifically based and statistically valid national estimates, to be used for education, research, and policy development.
