Alberta’s feral horse management framework

Sep 26, 2023

Currently more than 1,400 feral horses are located across six equine management zones in Alberta. Some equine management zones are facing significant challenges to the long-term sustainability of the ecosystem because of the number of horses on the landscape.

Alberta’s public rangelands are productive ecosystems that support many land uses, including recreation, forestry and resource extraction, wildlife, livestock and feral horses. All these uses need to be managed and balanced to ensure rangelands do not become degraded.

As the feral horse population grows, horses move from areas with good foraging opportunities into areas that are less able to support them. This puts pressure on other wildlife and livestock and creates challenges for ecological stability.

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.
