Three treated soybean meal (SBM) products: 1) nonenzymatically browned SBM (SoyPass®); 2)expeller SBM (SoyPlus®); and 3) a product of an unpublished manufacturing process (AminoPlus®), were compared using the following measurements: undegraded intake protein concentration (UIP), true nitrogen digestibility (TND) and metabolizable protein (MP) concentration. Soy Pass had the highest UIP, TND and MP values of the three treated SBM, followed by AminoPlus and then SoyPlus. The degree of heating may explain the differences in the three treated SBM products.
