Conditions During Expander Processing of Soybean Meal and Raw Soybeans Affect Nutrient Digestibility in Finishing Pigs

Kansas State University Swine Research. Expander processing improved nutrient digestibility in diets with soybean meal and raw soybeans. Furthermore, with 600 psi cone pressure (20 kWh/ton of specific energy input), the diets with raw soybeans had equal or greater digestibility of nutrients compared to the soybean meal-based control diet.
