An evaluation of 10-G brand direct-fed microbial for yearling steers fed finishing diets containing wet distillers grains12

WDGS and the finishing diet contained 68% steam flaked corn on a DM basis. Prior to the initiation of the experiment, WS and WDGS were mixed together using a vertical screw-type truck-mounted mixer box in the ratio of 2:5 (kg:kg) WS to WDGS on a DM basis, stored in a single pile, packed with a tractor, and covered with plastic. The WS and WDGS mixture was added to each batch of feed as one commodity during diet manufacturing. Overall ADG, DMI, G:F, and NE recovery were similar across treatments (P > 0.10). Hot carcass weight, YG, QG, maturity, and marbling score were similar across treatments (P > 0.10). Carcasses from steers receiving 10-G had a greater (P < 0.05) percentage of KPH compared with CON carcasses. Performance and carcass merit for yearling feedlot steers fed steam-flaked corn-based diets containing WDGS were not improved by 10-G brand DFM.
