Dr. Katelyn Gaffield & Sierra Collier: Soybean Meal Quality Variability | Ep. 217 | The Swine Nutrition Blackbelt Podcast

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Katelyn Gaffield from Kansas State University and graduate researcher Sierra Collier discuss a nationwide survey evaluating soybean meal quality and consistency. They share key findings on crude protein stability, variation in fat content, trypsin inhibitor levels, and implications for swine diet formulation. The discussion highlights opportunities for improved communication between producers and processors. Listen now on all major platforms!

“Trypsin inhibitor levels ranged widely from very low values to levels that could negatively impact nursery pig performance when included in diets at higher concentrations.” - Dr. Katelyn Gaffield
