Thousands of cattle converge in Madison for 57th World Dairy Expo

By Tim Peterson

For Emily Yeiser Stepp, the week of the World Dairy Expo in Madison ranks right up there with Christmas as one of her favorite times of the year.

Stepp has been coming to Wisconsin for the expo — the biggest trade show dedicated to dairy in the world — since 2005 as a cattle exhibitor and a judge.

This week, her family’s pair of Brown Swiss calves made the trip with them to compete at the expo. “PSwift” and “Patagonia” each earned top-10 finishes among the roughly 3,000 head of cattle from the United States and Canada assembled on the Alliant Center grounds.

Stepp also serves on the board of the expo and is a leader with the National Milk Producers Federation. The week is an opportunity to represent her organization and meet with stakeholders up and down the dairy supply chain.

She talked with WPR’s “Wisconsin Today” about the event and some challenges facing the dairy industry, including threats like bird flu being found in cattle and the Farm Bill potentially expiring next week.

Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
