Iowa State University Examines Truck Washing and Decontamination

Mar 17, 2025

Research conducted by Iowa State University suggests swine producers and transporters can reduce truck washing and decontamination costs through the strategic scheduling of truck washing.
Iowa State University, with funding provided through the Swine Health Information Center Wean-to-Harvest Biosecurity Research Program in partnership with the Foundation for Food and Agriculture Research and Pork Checkoff, used computer modeling to determine how different levels of swine transport trailer washing impact the spread of porcine epidemic diarrhea virus.
SHIC Associate Director Dr. Lisa Becton says the study found increasing the decontamination rate significantly reduces PED spread but it's not always economically plausible to wash 100 percent of the trailers 100 percent of the time.

Quote-Dr. Lisa Becton-Swine Health Information Center:
This modeling really does show the impact of network connectivity between sites, between systems and even in different geographic regions.
While it does look at different scenarios, this information can help both production managers and transportation managers and their veterinarians assess what are the risks in their particular area and then try to understand that it may not be necessary to wash 100 percent of the vehicles all of the time and still be able to take advantage of reduction in disease risk.

Video: WARNING! Rough Start To Breeding Season!!

WARNING! Sheep Breeding Season Begins With A Bang! Breeding season is officially underway at Ewetopia Farms, but it didn’t exactly start the way we planned!

This vlog begins with us sorting through our rams to find the perfect match for a customer’s breeding program. What should have been routine quickly turned dangerous when one of our more nervous rams panicked. In seconds, Arnie’s knee was injured, and then I was slammed hard onto the concrete floor — both of us taken down by one ram!

Thankfully, it was just bruises, but it’s a reminder of how unpredictable and powerful mature rams can be. Once we recovered, it was time to get back to the real work — the start of breeding season.

We sorted the ewes into four breeding groups (two Suffolk and two Dorset), checking parentage as they ran through the chute, deworming those that needed it, and setting aside thinner ewes for session two of breeding season in a month’s time.This staggered approach keeps lambing organized and prevents overcrowding in the barns.

From rogue rams to the excitement of new breeding groups, this episode is full of action. Stay tuned for the next vlog, where we’ll share how we chose the rams for each group!
