Nutritional value of extruded full-fat soybean meal for poultry

Properly processed extruded full-fat soybean meal is a high-quality source of energy and protein for poultry.   High-shear extrusion processing deals with a short-time (20sec), high-temperature (up to 320°F) and high-pressure (40 atm) cooking condition which leads to rupturing cell wall, liberating oil, and protein denaturation. Consequently, lipolytic enzymes and anti-nutritional factors (trypsin inhibitors and urease) will be deactivated. The nutritional quality and amino acid digestibility
