USDA Releases Findings from Comprehensive Study on Small Swine Operation

In a recent development, the U.S. Department of Agriculture (USDA) has unveiled the outcomes of an extensive study examining small swine operations—farms managing fewer than 1,000 hogs. This study, conducted in June and July 2021 by USDA’s National Animal Health Monitoring System (NAHMS) in collaboration with the National Agricultural Statistics Service (NASS), delves into health and production practices within this segment. Covering approximately 5,000 swine operations across 38 states, representing around 95% of small-scale U.S. swine farms, the report explores trends in health and disease management, pig movements, mortality rates, slaughter channels, and draws comparisons between small and large operations.

While the results from a concurrent study on larger operations, conducted from July 2021 to January 2022, are still pending, the released findings offer valuable insights into the dynamics of smaller swine operations. The National Pork Producers Council (NPPC) actively promoted the NAHMS-NASS study, urging pork producers to participate. The implications of these findings are significant for the pork industry, particularly in understanding the nuances of smaller operations that play a pivotal role as primary suppliers of niche-market products.

Video: Heat Stress in Pigs: What to Prepare for Before Next Summer - Dr. Joshua Selsby

In this episode of The Swine it Podcast Show Canada, Dr. Joshua Selsby from Iowa State University explains how heat stress affects swine biology and why now is the ideal time to prepare for next summer’s challenges. He breaks down its effects on muscle function, immune responses, and long-term metabolic outcomes. Learn how early planning can protect herd performance when temperatures rise again. Listen now on all major platforms! "Heat stress leads to a cascade of biological damage, beginning with metabolic disruption and expanding across multiple organ systems." Meet the guest: Dr. Joshua Selsby is a Professor in the Department of Animal Science at Iowa State University. With over 15 years of research on skeletal muscle physiology and heat stress, he focuses on understanding how thermal stress disrupts swine metabolism, immune function, and muscle integrity.
