Book Description
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.

Book Description
A series of five trials were conducted to evaluate grain processing, distiller's grains inclusion in finishing diets, interactions between distiller's grains and dry-rolled corn (DRC) or steam-flaked corn (SFC), efficacy of removing roughage in the presence of distiller's grains and the digestibility of distiller's grains in steam-flaked and dry-rolled corn diets. The first trial was designed to determine the optimum flake density of SFC in beef finishing diets. Diets consisted of corn flaked to densities of 360, 411, or 462 g/L. Observed improvements in mill production would support increasing flake density; however numerical decreases in animal performance offset economic benefits of increased productivity. The second trial was conducted to evaluate optimum levels of sorghum wet distiller's grains in finishing diets. Crossbred yearling steers were fed diets containing DRC or SFC and levels of distiller's grains were 0, 10, 20, or 30% of diet dry matter. Distiller's grains can effectively replaced a portion of the corn in finishing diets, but their nutritional value was greater in DRC diets than in SFC diets. In trial 3, crossbred heifers were fed diets containing SFC with 0% DDG and 15% corn silage (CS), 25% DDG and 15% CS, or 25% DDG and 5% CS. In trial 4, crossbreed heifers were fed diets similar containing DRC or SFC with 0% DDG and 15% CS, 25% DDG and 15% CS, or 25% DDG and 5% CS. Results indicate that roughage levels can be reduced in feedlot diets containing DDG with no adverse effects on performance or carcass quality. The fifth trial was a metabolism study conducted to evaluate the digestibility of DDG in beef cattle. Treatments consisted of DRC with 0% DDG, DRC with 25% DDG, SFC with 0% DDG, and SFC with 25% DDG. There were no significant grain processing by distiller's grain interactions observed in main effects. In conclusion optimum flake density was 360 g/L, feeding distiller's grains has a greater value in DRC diets vs. SFC diets, roughage level and type are important in formulating finishing diets, roughage can be reduced when feeding distiller's grains, and ruminal ammonia, and pH are decreased and ruminal lactate is increased when feeding DDG and SFC.

Book Description
Three methods of forage-finishing (pasture, silage, hay) for beef cattle were used to evaluate growth performance, carcass traits, meat quality, and fatty acid composition relative to grain-finished beef. Two hundred steers (100 Angus, 100 Hereford) were equally allocated (based on size) to 2 locations, evaluating alfalfa or grass forages as alternatives to grain. Growth performance and carcass traits were greater for grain-finished steers. Forage-finishing increased (P 0.02) concentrations of alpha-linolenic acid and total omega-3 fatty acids vs. grain-finishing. A trained taste panel found no difference (P 0.05) in tenderness between forage-and grain-finished beef. Beef flavour intensity was greater (P

Book Description
Distillers grains plus solubles (DGS) have been widely utilized in beef cattle diets. Fractionation of the corn kernel pre- and post-fermentation has changed the composition of DGS and allowed for the production of other feed byproducts over time. The use of fractionated DGS and other feed byproducts from the ethanol industry has not been heavily researched in beef cattle diets. Three experiments were conducted to evaluate the effect of feeding high protein distillers grains (HiPro DDG) and corn bran plus solubles (Bran + Solubles) in beef cattle diets. Experiment 1 evaluated the effect of byproduct type on finishing performance and carcass characteristics. Experiment 2 evaluated the effect of byproduct type on nutrient digestibility, ruminal pH, ruminal VFA production, and in vitro gas production. Byproducts replaced corn at 40% of diet DM in Exp. 1. Experiment 3 compared feeding Bran + Solubles to wet DGS at 20 and 40% of diet DM compared to a corn control. In Exp. 2, Feeding HiPro DDG or Bran + Solubles resulted in decreased digestibility compared to corn or traditional wet and dry DGS, but increased energy intake. Traditional wet and dry DGS also resulted in decreased digestibility while energy intake was increased. Volatile fatty acid profiles and pH parameters were not different across treatments. Feeding HiPro DDG and Bran + Solubles improved gains and feed efficiency compared to traditional dry or wet DGS and corn. Compared to wet DGS, Bran + Solubles resulted in similar performance and carcass characteristics. Increased inclusion of both byproducts resulted in a linear increase in carcass weight. Overall, nutrient digestibility for HiPro DDG or Bran + Solubles is similar to traditional wet or dry DGS while performance was increased.
