Issues on ruminant starch digestibility (STRD) include vitreousness—harder starch—vs. soft, floury endosperm in commercial corn germplasm. As part of a series of Pioneer Forage Forum segments highlighting STRD research, Dr. Bill Mahanna, Pioneer Global Nutritional Sciences Manager, condenses decades of research on this topic. His review includes recent conclusions, with viewpoints on how to identify real-world findings and make practical decisions, driven by factors ranging from processing of feed to digestion.
