Utilizing reduced-fat modified distillers grains with solubles (RFMDGS) was evaluated using fifty crossbred steers. Steers were randomly fed one of four dietary treatments for 181d, fed a common diet for 3d, and harvested at a commercial abattoir. Hot carcass weight, 12th rib BF, REA, %KPH, and marbling score were collected 24h postmortem. Strip loins were collected for vacuum purge loss evaluation and fabricated for drip loss, cook loss, WBSF, sensory evaluation, and retail shelf life evaluation. Shoulder clods were used to create ground beef and bologna. Ground beef was utilized for composition analysis, retail shelf life evaluation, and TBARS analysis while bologna samples were evaluated for sensory attributes and retail shelf life evaluation. Twelfth rib BF was analyzed for objective color, fatty acid composition, and calculated iodine value. Results indicate that feeding high levels of RFMDGS within finishing feedlot diets may cause minimal detrimental meat quality impacts.
