Beefenomics: Corn-Feeder Cattle Price Connection

By William Secor

The ups and downs of summer weather are upon us affecting a host of agricultural markets. The focus of this note is looking at how feed costs can affect cattle markets, specifically corn prices. In general, if growing conditions are worse than expected (e.g., a drought), corn prices increase because markets anticipate a smaller than expected crop. In contrast, if growing conditions are better than expected (e.g., ideal weather), corn prices will fall because markets anticipate a larger than expected crop.

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.
