Book excerpt: The objective of this study was to determine the effects of Wet Brewer's Grains (WBG) on the growth performance, carcass performance, and meat quality of finishing cattle. Twenty-four (n=24; 12 heifers -- 303kg, 12 steers -- 346kg) calves of Simmental-Angus genetics were utilized. Calves were paired by sex, blocked by BW within sex in a 2 x 2 factorial arrangement with three replications per treatment, and fed for 140d. Control diets were a conventional corn silage -- shelled corn finishing-diet. Experimental diets modeled the control diet with the inclusion of WBG on a thirty-percent DM basis. Cattle were visually appraised by an industry procurement agent for degree of finish. Finished cattle were transported 160km for slaughter under USDA-FSIS inspection. Primal ribs (IMPS #1103) were obtained and transported to ISU's Meat Lab. Ribeye steaks (IMPS #1112) were fabricated from the ninth -- eleventh ribs for further meat quality analyses. Statistical analysis was modeled in a two-way fixed ANOVA utilizing the MIXED procedure of SAS. No differences were observed in Total Gain and ADG between diets respectively (P = 0.6919). Average Daily Feed Disappearance (ADFD) increased in WBG calves (P 0.0001). Decreases in G:F were observed in WBG calves (P = 0.0121). No differences were observed in HCW, YG, or QG respectively (P 0.05). No differences were observed in Warner-Bratzler Shear Force, Package Purge, or Cook Loss measurements (P > 0.05). This data indicates WBG inclusion supports growth performance, carcass performance, and meat quality of finishing cattle similar to a conventional finishing diet.
