This webinar explores how an integrated, systems-based understanding of the nutrient cycle can drive more sustainable pork production. By examining both feed utilization within the animal and nutrient management beyond the barn, the discussion connects nutritional strategies and manure treatment technologies as key components of the pork ecosystem. Presenters will highlight advances in precision feeding, enzyme use, and feed processing that improve nutrient efficiency and reduce environmental impacts, as well as research optimizing zinc inclusion to balance performance and sustainability. This presentation was originally broadcast on November 14, 2025.
