Auction Marts Dealing With Increased Numbers

It's a busy time for livestock auction marts.

Harold Unrau is manager of Grunthal Livestock Auction Mart.

"We're starting to see more cattle rolling through the ring here, all because of drought of course. The further north you go, the worse the drought is. They're trying to figure out what they're going to do with their cattle because they're running out of pasture. We actually had some cattle in here from up at Fisher Branch because they are out of grass. Locally here, if we get a rain here this week or beginning of next week, I think our producers will kind of be okay, at least most of them. If we don't get a rain for the next week or two, they're going to be out of pasture and the hay is really in short supply."

Unrau says normally throughout the summer they see about 100 head a week. This year that number is around 300.

He adds they are currently gearing up for an early fall run.

Video: Porcine Gut Models in Nutrition Research - Dr. Li-Hsuan Chen



In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Li-Hsuan Chen, postdoc researcher at Aarhus University, discusses how porcine intestinal cell lines and organoids can help study the impact of nutrition on gut health. He explains how in vivo piglet trials identify diet-driven shifts in microbiota and metabolites, while in vitro models allow researchers to test specific metabolites, barrier function, immune markers, and future organ-on-chip systems before moving back to animal studies. Listen now on all major platforms!

"In vitro models can reduce early animal use by helping researchers screen nutritional candidates before moving back to in vivo trials."

Meet the guest: Dr. Li-Hsuan Chen / li-hsuan-chen-9a95a7279 is a postdoc researcher at Aarhus University in Denmark. Research focuses on porcine gut health, host-microbe interactions, cell lines, and organoids, with PhD work at Aarhus University studying how dietary protein and amino acid levels shape gut microbiota, microbial metabolites, and intestinal epithelial responses.
