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

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.

FLEECED! Sheep Shearer Hands Over Clippers!

Video: FLEECED! Sheep Shearer Hands Over Clippers!

It's sheep shearing day at Ewetopia Farms! ?? Our Dorset lambs and ewes are getting fleeced — and for the first time, our shearer hands over his clippers to a beginner. We finish shearing the last of our adult ewes and this year’s Dorset ewe lambs.

From moving the sheep between barns, loading them into chutes, and watching the wool come off, this is always one of the most satisfying days on the farm. But this video has a twist — we welcomed a new helper, Gian, who’s not only lending a hand but also learning how to shear! With guidance from our experienced shearer, he got a crash course in sheep shearing and even tried his hand at shearing a couple of lambs himself.

You’ll see firsthand how both teacher and student handled this unique challenge. Shearing is more than just removing wool — it’s about sheep health, comfort, and giving us a closer look at the flock. It’s always amazing to see the transformation from woolly sheep to freshly shorn ewes and lambs.
