When soybeans are crushed, the oil may be solvent extracted and the resulting defatted soybeans are known as soybean meal (SBM). However, the oil may also be mechanically expelled from the beans and the defatted soybeans resulting from this procedure is an ingredient known as soybean expellers. The expelling procedure is less efficient in removing oil from the beans and soybean expellers, therefore, contain more residual oil than SBM. Soybean expellers can be produced using different technologies, and a new procedure involving a patented high shear dry extrusion procedure was recently developed (Insta-Pro International, Des Moines, IA). There are however, no data for the digestibility of amino acids (AA) in the soybean expellers that are produced from this procedure. Therefore, the objective of this research was to test the hypothesis that the standardized ileal digestibility (SID) of crude protein (CP) and AAis greater in soybean expellers than in SBM when fed to growing pigs.
