2016 Nebraska Beef Cattle Reports
The objective of this study was to evaluate performance and carcass characteristics of heifers fed a newly developed direct- fed microbial (DFM), using 336 heifers in a pen study. Th e experiment consisted of feeding corn (CON) or 40% modified distillers grains plus solubles (40MDGS) and presence or absence of DFM added as a top- dress. No significant differences were observed for heifer performance and carcass characteristics due to DFM. Feeding MDGS increased ADG, while reducing F:G compared to CON. The DFM developed for this study did not enhance performance as was hypothesized, while feeding MDGS did.
