Minnesota's Swine & U

In this podcast, Swine Extension Educator Sarah Schieck Boelke once again speaks with Lyle Lange and Mike Walker of Lange Ag Systems in Willmar, MN. This time she speaks to Lyle and Mike about Fall/Winter ventilation basics for swine barns. Lyle has over 46 years of experience in the livestock industry, and Mike has 26 years of experience. With the change of season to Fall and then Winter, there are some fundamental things producers should evaluate in the swine barn to ensure ventilation is at optimal performance. Lyle and Mike define basic ventilation terminology and provide practical strategies for common ventilation issues, such as cleaning soffits and fans, checking belts, and calibrating inlets. Lyle and Mike also discuss how to ensure the heating system is ready when needed.Recorded August 10, 2026.

In this podcast, Swine Extension Educator Sarah Schieck Boelke speaks with Lucas Ferreira, Master’s student in Veterinary Science in the Department of Veterinary Population Medicine, about his research on trailer contamination at the harvest plant facilities during the unloading of market hogs. The study includes two harvest facilities that Lucas and others visit regularly throughout the year to collect environmental samples from the unloading dock and trailers to analyze for pathogens, such as PRRSv, PEDv, PDCoV, and SVA. The research also includes talking to the drivers about their biosecurity practices. In the podcast, Lucas gives preliminary results and explains the research is ongoing. Year 1 of 2 has been completed.Learn more about trailer contamination at the harvest plant facilities during unloading of market hogs as featured in the podcast.Assessment of PEDV Trailer Contamination at the Harvest Facility blog post on Minnesota Swine News.SHIC-Funded study quantifies trailer contamination risk at harvest plants posted in Swine Health and Information Center website.

In the podcast, Swine Extension Educator Sarah Schieck Boelke speaks with Sara Williams, who recently completed her master's of science degree in Animal Science with an emphasis in Swine Nutrition from the University of Minnesota's Department of Animal Science. Sara’s MS research involved formaldehyde-based feed sanitizers in sow feed to reduce pathogens. Her research gives some promising results on this topic.Learn more about formaldehyde-based feed sanitizers in sow feed featured in the podcastAbstract published in Journal of Animal Science, Volume 103, Issue Supplement 1. doi: 10.1093/jas/skaf102.313.

In the podcast, Swine Extension Educator Sarah Schieck Boelke speaks with Drs. Kim VanderWaal and Igor Paploski about PRRS virus Classification. Both are faculty members in the University of Minnesota Veterinary Population Medicine department. PRRS virus Classification is basically naming of the PRRS virus according to the genetic sequencing of the virus. Kim and Igor explain how PRRS viruses were classified previously and changes to how they are being classified based on their work.Learn more about PRRS virus classification featured in the podcastSwine Health Information Center fact sheet on the epidemiological insights on the PRRS-Loom Variant webtoolLink to PRRS-Loom Variant webtoolJournal article published in Epidemiology, Volume 10, Issue 2. doi: 10.1128/msphere.00709-24

In the podcast, Swine Extension Educator Sarah Schieck Boelke speaks with Rachel Schambow who is a researcher with the UMN Center for Animal Health and Food Safety at the College of Veterinary Medicine. Rachel speaks about the analysis her and her colleagues did of USDA’s Sick Pig Surveillance component at Iowa State University and the University of Minnesota Veterinary Diagnostic Laboratories. She also talks about USDA’s Sick Pig Surveillance program in general and how producers and veterinarians can support surveillance for African Swine Fever and Classical Swine Fever. University of Minnesota College of Veterinary Medicine Center for Animal Health and Food Safety have created informational sheets about the sick pig Veterinary Diagnostic Lab’s (VDL) surveillance program to help producers and veterinarians understand what it is and how they can participate. There are two versions of the informational sheets - one is aimed towards the intensive commercial swine industry, while the other is aimed more at non-swine veterinarians and general audiences.

In the podcast, Extension Swine Educator Sarah Schieck Boelke speaks with Gabriella Lima who recently finished her Master of Science degree in the Department of Animal Science. Gabriella speaks about a research project she worked on. The research project was very comprehensive in what it all looked at, but specifically, Gabriella looked at the effects of growth performance and carcass characteristics when feeding hybrid rye to organically raised growing-finishing pigs. Gabriella does briefly share the other aspects of the research project that were studied by others, but didn’t share those results.Learn more about research featured in the podcastAbstract published in the Journal of Animal Science, volume 102, Issue Supplement 2, Pages 58-59.
