Abstract

An individual feeding experiment (n = 60) was conducted to evaluate the effects of feeding a direct- fed microbial (DFM) or not on performance of finishing steers fed 0 or 40% modified distillers grains (MDGS) in a 2 × 2 factorial design. Gain and F:G were improved when cattle were fed MDGS compared to the corn diet. No significant differences (P ≥ 0.23) were observed between cattle fed DFM or not for DMI and ADG. However, numeric advantages were observed for F:G when cattle were fed a DFM, with a 5% improvement in feed efficiency for steers supplemented with DFM.
