Recorded live at IPPE in Atlanta, GA, this episode features Dr. Melina Bonato and Graziela Alves Valini of ICC Animal Nutrition breaking down the science behind yeast supplements. The discussion covers yeast types, functional benefits, and practical considerations for using yeast in animal nutrition programs, offering clear, science‑based insights from the show floor.
Yeast supplements play a critical role in modern animal nutrition, gut health, and feed efficiency, but not all yeast products work the same way. In this episode of the Real Science Exchange, recorded live at IPPE in Atlanta, Dr. Melina Bonato of ICC Animal Nutrition breaks down the science behind yeast supplements, yeast cultures, and pure yeast products, and explains how different yeast types are produced, processed, and applied across species.
The discussion covers yeast functionality in the gut microbiome, differences between autolyzed yeast, hydrolyzed yeast, and yeast cell walls, and how nutritionists and producers can select the right yeast solution for swine, piglets, and animals in high‑stress production phases such as reproduction and transition. The episode concludes with practical guidance on matching yeast supplements to production goals for improved animal performance and health.
