Solutions to Meet the Need for Feed

Mar 10, 2023

Livestock and poultry have been a valuable part of the global agricultural landscape for millennia. As global meat production has quadrupled over the past fifty years, the corresponding growth in production and consumption of animal products and feed requires increased attention to the impacts of these intertwined systems and processes. As a component of the food system’s footprint, animal-sourced foods currently account for 11% of global greenhouse gas emissions, 12% of global freshwater consumption and have been responsible for 65% of global land use change from 1961-2011. Collective action across the feed value chain can deliver positive impacts to climate, biodiversity, water use, and protection of critical landscapes.

Video: Methionine Requirements for Lactating Sows - Cierra Kozole

In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
