Virtual Fencing Grants Seek To Bolster Wildlife Corridors

By Jenna McMurtry

Move over barbed wire and electric fences. A “friendlier fence” to wildlife is gaining footing in the Greater Yellowstone Ecosystem.

For the second year in a row, the Bozeman-based think tank Property and Environment Research Center has awarded grants to ranches in the region to make virtual fences more accessible.

“It allows a farmer or a rancher to better and more precisely manage their livestock without the need for physical fences on the landscape,” said Travis Bramer, the organization’s director of conservation.

Across Wyoming and Idaho, eight ranches have received grants to purchase and maintain the costly equipment that’s altering the ranching industry. This year, Bramer’s nonprofit partnered with the Ricketts Conservation Foundation, which contributed a third of the $600,000 fund.

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.”
