The Swine Nutrition Blackbelt Podcast - Nelson Arias: US Soybean Insights | Ep. 196
Nov 06, 2025In this episode of The Swine Nutrition Blackbelt Podcast, Nelson Arias from the University of Illinois shares recent research on the nutritional consistency of extruded full-fat soybeans across different US regions. He explains how minimal variation in amino acids, energy, and phosphorus digestibility can simplify diet formulation. Listen now on all major platforms!
What will you learn:
- Soybean nutrient consistency
- Amino acid digestibility
- Regional sourcing impact
