In this third part of the U.S. Soy breakout session (“High soy for improved health”) at the 2025 Allen D. Leman Swine Conference, Dr. Ryan Dilger, professor of animal sciences at University of Illinois Urbana-Champaign, explains the potential mechanisms behind how isoflavones and saponins in soybean meal benefit swine health.

Key takeaways include:

• Soy bioactives are functional feed components with high potential.
• Isoflavones and saponins are natural and complementary immune modulators.
• They are not a replacement for vaccines/therapeutics, but are cost-effective and supportive.
• There is a clear need to develop practical dietary strategies to support immune resiliency.
