Book Description
Two experiments were conducted to determine the effects of treating sorghum wet distiller's grains with solubles (SWDGS) with an enzyme complex, or enzyme complex-buffer combination on diet digestibility and feedlot performance. Experimental treatments were as follows; 1) untreated SWDGS (Control), 2) addition of an enzyme complex to SWDGS (Enzyme); and 3) addition of enzyme complex and limestone buffer to SWDGS (E+B). Sorghum WDGS, regardless of treatment, was included at 45% DM (DM basis) of a steam-flaked corn-based finishing diet. The enzyme complex (Biozyme, Inc., St. Joseph, MI) was a proprietary blend containing both exogenous and endogenous hemicellulase, cellulase, and amylase enzymes, and was added at rate of 6 L/dry ton and 6.2 L/dry ton of SWDGS in Experiment 1 and 2; respectively. In the first experiment, six crossbred beef steers (initial BW = 577 ± 6.9 kg) were used to evaluate the effects of treating SWDGS with an enzyme complex or buffered enzyme complex on digestibility of nutrients. No differences (P > 0.28) in DMI, or digestibility of DM, OM, and starch between treatments were detected. Steers fed E+B treatment had higher (P = 0.07) ruminal pH than Control or Enzyme steers. Neutral detergent fiber digestibility tended (P = 0.15) to be greater for E+B fed steers. In a second experiment, 54 beef steers (initial BW = 370 ± 9 kg) were fed in a finishing study evaluating the same dietary treatments as the first experiment. No difference (P > 0.31) in DMI, ADG, or G:F was detected for the entire feeding period when Enzyme fed cattle were compared to Control. In contrast to the first experiment, DMI for the feeding period was lower (P = 0.03) for E+B fed cattle compared to Enzyme. There was no difference (P = 0.39) in ADG during the entire feeding period between Enzyme and E+B fed cattle; however, G:F was greater (P = 0.05) for E+B fed cattle compared to Enzyme. Standard carcass measurements did not differ (P > 0.43) between Enzyme and Control treatments. Most standard carcass measurements did not differ (P > 0.42) between E+B and Enzyme treatment, however, E+B cattle had less rib fat (P = 0.05) and had lower (P = 0.02) yield grades. Furthermore, the E+B fed cattle tended to have (P = 0.06) larger ribeye areas than Enzyme cattle. In conclusion, while treating SWDGS with a buffered enzyme complex containing primarily fibrolytic enzymes effects had positive on NDF digestibility, no corresponding improvements in cattle performance were detected.

Book Description
All dry milling ethanol plants produce wet distillers grains (WDG) and distillers solubles (DS). Depending on the plant, WDG and DS will be combined to produce wet distillers grains plus solubles (WDGS). Some plants will partially dry WDGS and market modified distillers grains plus solubles (MDGS), or other plants will completely dry WDGS to produce dried distillers grains plus solubles (DDGS). These products have been shown to contain greater feeding values than the corn it replaces in finishing diets. However, as drying intensity of distillers grains plus solubles (DGS) increases, the feeding value relative to corn decreases. Three finishing experiments and two metabolism experiments were conducted to evaluate the effect drying WDGS has on finishing cattle performance and carcass characteristics and the effects on nutrient digestibility. Diets containing DGS had greater ADG and were more efficient than the corn-based control. As a result, cattle fed DGS had heavier HCW and greater 12th rib fat thickness at harvest. Using the G:F values, all types of DGS regardless of moisture content had greater feeding values than the corn it replaced. Additionally, WDGS had greater feeding values than MDGS and DDGS, and MDGS had a greater feeding value than DDGS. Although not significant, diets containing WDGS had numerically greater NDF digestibility than diets containing DDGS. Organic matter digestibility was improved for WDGS compared to DDGS. Completely and partially drying WDGS reduces the feeding value in finishing diets and reduces OM digestibility.

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 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
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.
