Learn How Drought and Smoke Have Impacted Crops during Northeast Iowa Field Day on August 31, 2023

The annual fall field day at Iowa State University’s Northeast Research and Demonstration Farm will feature presentations on how drought and smoke have impacted crops, corn rootworm and short stature corn.

The event will be held Aug. 31, beginning with a complimentary meal at noon, sponsored by the Iowa Soybean Association, and run until 4:30 p.m.

The field day is free and open to the public. It starts at the Borlaug Learning Center Headquarters, located on the research farm.

From Nashua at the junction of Highway 218 (Exit 220) and County Road B60, go west on Highway B60 1.1 miles to Windfall Ave., then south 1 mile to 290th St., then east 0.2 miles to the farm. Certified Crop Adviser Credits will be available.

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.”
