Abstract: Shortening Duration of Swine Exhibitions to Reduce Risk for Zoonotic Transmission of Influenza A Virus

Sep 23, 2022

Reducing zoonotic influenza A virus (IAV) risk in the United States necessitates mitigation of IAV in exhibition swine. We evaluated the effectiveness of shortening swine exhibitions to <72 hours to reduce IAV risk. We longitudinally sampled every pig daily for the full duration of 16 county fairs during 2014-2015 (39,768 nasal wipes from 6,768 pigs). In addition, we estimated IAV prevalence at 195 fairs during 2018-2019 to test the hypothesis that <72-hour swine exhibitions would have lower IAV prevalence. In both studies, we found that shortening duration drastically reduces IAV prevalence in exhibition swine at county fairs. Reduction of viral load in the barn within a county fair is critical to reduce the risk for interspecies IAV transmission and pandemic potential. Therefore, we encourage fair organizers to shorten swine shows to protect the health of both animals and humans.

Video: Do Stress-Resilient Sows Raise Better Piglets? - Dr. Andrea Luttman?

In this special rerun episode of The Swine it Podcast Show Canada, Dr. Andrea Luttman from Michigan State University explores how gestational social stress affects sow resilience and piglet development. She explains physiological indicators like cortisol patterns, behavioral differences, and their implications for long-term performance. Listen now on all major platforms!

“Resilience to stress means animals are either minimally affected or can recover quickly after experiencing a stressor.”

Meet the guest: Dr. Andrea Luttman / andrea-luttman-47ab74171 is an Assistant Professor at Michigan State University specializing in swine production systems management. She earned her Ph.D. in Genetics and Genome Sciences and focuses her research on swine physiology and stress resilience. Her work examines social stress in gestating sows, offspring development, breeding herd longevity, and gene-environment interactions to improve production efficiency and sustainability.
