Book Description
Two experiments were conducted to evaluate corn distiller's solubles (CDS), a co-product from dry grind ethanol plants, in beef steers fed corn-based diets. In Exp. I, four pens of steers were fed for 109 d diets containing 0, 4, 8 or 12% CDS. Daily feed, gain and gain/feed were 9.4, 10.1, 10.0, and 10.1 (kg/d); 1.75, 1.78, 1.76, and 1.79 (kg/d); 0.185, 0.177, 0.176, and 0.179; for the four respective diets. Feed intake increased when CDS was fed (P = 0.012). Gain, gain/feed, and carcass traits were not statistically different (P> 0.1). In Exp. II, ten steers were used in a digestion study to evaluate diets containing 4 and 8% CDS, or 10 and 20% wet corn distillers grain with solubles (WDGS). The steers were placed in digestion crates for total collection of feces and urine. Intake (kg/d) of DM, starch, NDF, ADF, CP, and fat were: 7.99, 8.71, 8.62 & 8.41, 7.83; 4.92, 4.87, 4.93, & 4.81, 3.95; 1.19, 1.25, 1.19, & 1.42, 1.42; 0.43, 0.48, 0.45, & 0.56, 0.55; 0.96, 1.08, 1.03, & 1.03, 1.03; 0.27, 0.35, 0.43, & 0.43, 0.50; for 0, 4 or 8% CDS and 10 or 20% WDGS. Respective apparent digestibility of DM, starch, NDF, ADF, CP, and fat were 79, 78, 76 & 77, 76; 97, 94, 95, & 95, 94; 53, 52, 46 & 52, 56; 41, 45, 37, & 48, 50; 72, 72, 70, & 69, 69; 63, 66, 65, & 68, 75. Feeding distillers co-products did not affect DM intake or digestibility of NDF, ADF, or CP (P> 0.05), but did increase fat intake (P

Book Description
In recent years, there has been a dramatic increase in grain-based fuel ethanol production in North America and around the world. Whether such production will result in a net energy gain or whether this is sustainable in the long term is under debate, but undoubtedly millions of tons of non-fermented residues are now produced annually for global tr

Book Description
Three feedlot experiments evaluated the effects of added urea to finishing diets containing less than 20% WDGS. In Exp.1, a significant interaction was observed for G:F between urea concentration and distillers concentration in the diet. Feeding urea in diets with 10% WDGS had no significant impact on animal G:F. Urea included in diets with 15% WDGS had a quadratic impact on G:F with urea included at 0.5% of diet DM having the greatest performance. When adding urea to diets containing 20% WDGS, a quadratic impact on G:F was observed where urea included at 0.5% of diet DM reduced G:F. In Exp. 2 there were no interactions between urea concentration and WDGS concentration. Increasing concentration of WDGS in the diet improved G:F by 4.7%. The addition of urea to the diet had minimal impact on performance although cubic effects of urea inclusion were observed suggesting variation in the data. For Exp. 3 no difference was observed, for either urea concentration or WDGS concentration in the diet, however, DMI was reduced when urea was included in the diet at 1.2%.Two experiments evaluated the effects of the addition of yeast extracted solubes (EXP) and yeast to finishing diets on performance, carcass characteristics, and nutrient metabolism. In Exp. 1, feeding increased EXP in the diet resulted in quadratic effects on performance with what appears as a linear decrease up to 15% EXP is included followed by a dramatic increase at 20% inclusion. Feeding similar concentrations of EXP when compared to conventional condensed distillers solubles (CONV) reduced animal performance. However, when yeast (YST) was added back to the EXP, performance is similar to CONV. Adding YST alone does not improve performance over the corn control. All concentrations of EXP and CONV performed worse than the corn control. In Exp. 2 no effects on measured nutrient digestibility were observed. However, DM intake and excretion were affected with tendencies for OM, NDF, ADF, and starch intakes to be affected. Digestible energy intake in Mcal/kg and TDN were affected by diet and appeared to follow similar patterns as the performance trial perhaps explaining the observed performance response.

Book Description
Corn condensed distillers solubles (CDS) is a protein and energy dense by-product from dry-milled production of ethanol. Recent oil extraction has posed modifications to the nutrient profile of CDS, suggesting that de-oiled CDS needs to be re-evaluated in beef cattle diets. Three experiments were conducted to evaluate the effects of CDS in high-concentrate diets, forage-based diets, as well as evaluate the effects of CDS on diet digestibility and rumen fermentation parameters in forage-based diets. Feeding CDS in high-concentrate diets up to 20% of the diet DM or in combination with wet distillers grains plus solubles (WDGS) improved performance and resulted in greater energy value compared to corn. Feeding values of 20% CDS or the combination of 16% CDS and 20% WDGS were 147 and 129% compared to corn, respectively. Feeding CDS in forage-based diets up to 40% of the diet DM diminished performance and resulted in a lesser energy value compared to corn. Linear decreases were observed in total tract digestibility of NDF and the acetate to propionate ratio in rumen fluid. Double-cropped forages following corn harvest offer livestock producers an opportunity to extend their grazing season on high quality forage in the fall. Additionally, crop producers may benefit from the implementation of grazing animals due to added soil nutrients and removal of residue. Therefore, an experiment was conducted to evaluate the effects of double-cropped oats following corn silage (CS) or high-moisture corn (HMC) on calf gains, forage production, and subsequent cash crop yields. Oats seeded after CS produced more forage biomass than oats seeded after HMC. Both treatments produced high quality oats (22% CP, 39% NDF, and 24% ADF averaged across treatments). Calf gains were greater grazing oats following CS compared to HMC at 1.10 and 0.84 kg / d, respectively. Across 1-yr of data, subsequent cash crop yields were not different for HMC and soybeans with increased CS yields in both covered/grazed and non-covered/non-grazed treatments compared to the covered/non-grazed treatment..

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.

Book Description
In its entirety this dissertation intended to address the impact of feeding several forms of de-oiled corn distillers grains plus solubles and the effect of supplementing OmniGen-AF as a potential antioxidant source for extending beef shelf life. In study one we learned that despite the de-oiling process, greater inclusion levels (65%, DM basis) of de-oiled wet distillers grains plus solubles (WDGS) causes an increase in polyunsaturated fatty acids (PUFA) similar to the levels obtained with full-fat WDGS. Lower inclusion levels (35 and 50%, DM basis) of de-oiled WDGS have intermediate PUFA content in comparison to 65% de-oiled WDGS, full-fat WDGS and a corn control diet (P 0.01). In study two cattle finished with 50% de-oiled dry distillers grain plus solubles (DDGS) also resulted in an increased PUFA content in muscle in relation to a corn control group (P
