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

Oct 04, 2024

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.

Video: Validating Net Energy in Commercial Swine Systems - Gustavo Lima

In this episode of The Swine Nutrition Blackbelt Podcast, Gustavo Lima, PhD candidate at Iowa State University, explains how soybean meal net energy is evaluated using growth assays and calorimetry. He discusses caloric efficiency, validation under commercial conditions, and differences between controlled and real-world environments. Gustavo also highlights practical implications for diet formulation and ingredient valuation. Listen now on all major platforms!

“Indirect calorimetry provides a precise estimation of ingredient energy, yet validation under production conditions remains essential for accurate application in real systems.”

Meet the guest: Gustavo Lima / gustavo-lima-a9867127 is a PhD candidate in Animal Science at Iowa State University, specializing in swine nutrition, ingredient evaluation, and energy metabolism. With over 15 years of experience across Latin America, his work focuses on soybean meal utilization, caloric efficiency, and applied research for commercial production systems.
