A comparative slaughter-feeding trial technique was used to determine the influence of various steam-processing treatments on the energy utilization and feeding value of wheat, corn, barley and milo for feedlot cattle. Processing of wheat, corn and barley by various steam-pressure-time combinations did not consistently improve their value compared to processing by a standard steam-rolling procedure. Steam-pressure processing of milo resulted in a 10 per cent improvement in the net energy for gain value of high-grain rations. The optimum time-pressure steam treatment was approximately 1.5 ± .5 minutes at 3.5 ± .5 kg/cm2. The improvement in the feeding value of steam-pressure-processed milo seems to be due to small, but additive, beneficial effects associated with an improvement in energy digestibility, more rapid rumen fermentation, and decreased food intake.
