Kansas Agricultural Experiment Station Research Reports
Evaluations of four soybean meal (SBM) products were conducted. The products were: solvent SBM (SSBM), expeller SBM (ESBM), lignosulfonate-treated SBM (LSBM), and SSBM treated with 0.05% Baker's yeast and toasted at 212ºF (YSBM). In situ ruminal degradations of YSBM and LSBM were slower than those of SSBM or ESBM; thus, ruminally undegraded protein contents of YSBM and LSBM were greater than those of SSBM or ESBM. The ruminally undegraded protein of all SBM products had similar small intestine digestibility when as-sessed by susceptibility to enzymatic digestion in vitro. Available lysine contents, estimated chemically or using standard chick growth assay, were …
