Extrusion is a relatively complex cooking and drying process that is commonly used in both the human and pet food industry. Extrusion utilizes a combination of steam and friction as heat sources to “cook” a formula under pressure. The sudden release of pressure as the product exits the die plate causes starch molecules to “explode” much like that of popcorn. This forms a unique “Expanded” food nugget that is highly digestible. A horse’s small intestine digestion of uncooked grains such as corn, rice, barley, etc.. typically runs between 30 and 45 percent. Gelatinized starch found in Victor Extruded Advantage horse feed digests at a rate exceeding 90% which represents a 200-300% increase in small intestine starch digestion.
