Crop Spraying Delayed

Aerial crop spraying has been delayed this year due to the later spring seeding.
 
Pembina Air Services Chief Pilot Jim Peters tells us what they're focusing on right now.
 
"Right now we're into the leaf disease on the wheat that we're trying to protect the flag leaf and keep it disease free," he said. "Following that we'll get into anthesis timing, the flowering of the wheat, so we'll be doing an application there."
 
Peters says insects have also been a concern.
 
"We were busy with some flea beetles and some cutworms but now it's kind of tapered off a little bit. Most guys are able to take care of it with their own unit."
 
He notes grasshoppers are also showing up, although the numbers haven't warranted planes going up.

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.
