Episode 44: Surveillance of African and Classical Swine Fevers in the U.S.
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.

Episode 43: Feeding hybrid rye to organic growing-finishing pigs.
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.
