The steers fed L consumed 3.2% less dry matter than cattle fed H (P<.05) and had 6.9% lower gains (P<.05). Feed efficiency tended (P=.15) to favor cattle fed H. The H milo was flaked 27% faster than M and 67% faster than L (P<.0001), resulting in lower production cost for the heavy flakes. In Trial 2, six ruminally cannulated steers were fed the same diets used in Trial 1 in a replicated 3×3 Latin square. After adaptation to the respective diets, the cattle were fasted and then overfed to simulate a drastic intake fluctuation. The L diet was fermented more rapidly than the H diet, resulting in greater ruminal pH depression (P<.10) following overconsumption. Under the conditions of this experiment, flaking milo more intensively than 28 lb/bu (58.7% starch gelatinization) resulted in decreased consumption, lower mill efficiency, and increased propensity for acidosis in finishing steers.BeefSteam flakingMiloDensityAcidosisMill EfficiencyConference paper
