Twenty ruminally fistulated beef steers free-choice access to prairie hay were used to evaluate the effect of increasing level of soybean meal (SBM) on forage intake and digestion.
Forage intake, total organic matter intake, and organic matter digestion were enhanced with
increasing level of SBM supplementation, although forage intake and digestion appeared to
plateau at higher levels. The concomitant rises in intake and digestion as supplemental SBM
increased resulted in an increase in total digestible organic matter intake, with the largest response to the initial increment of supplement.
