Book Description
The byproducts of making ethanol, sweeteners, syrups, and oils were considered less valuable than the primary products. But the increased livestock-feed market for such byproducts has switched that perception to one of the ethanol industry making grain-based ¿co-products (CP)¿ that have market value separate from the primary products. CP such as dried distiller¿s grains, corn gluten feed, corn gluten meal, corn oil, and brewer¿s grains have become economically viable components, along with traditional ingred., in feed rations. The CP have limitations, such as variable moisture content, product avail., nutrient excesses or deficiencies, and nutrient variability. These limitations affect how they must be handled and stored and how much they cost. Illus.

Book Description
Four finishing studies were conducted to optimize the use of ethanol and sugar beet byproducts in finishing diets containing dry rolled corn (DRC), steam flaked corn (SFC), or a combination of both. Data are limited for feeding combinations of corn processed by different methods (DRC and SFC) fed with wet distillers grains with solubles (WDGS). Also, limited data are available for feeding different levels of beet pulp in corn based adaptation and finishing diets. Lastly, the relationship between dietary fiber and sulfur (rumen degradable; RDS and rumen undegradable) and their impact on feedlot health is not well understood. Therefore, our objectives were to 1) determine the effects of feeding different ratios of DRC and SFC in diets that contain 35% (DM) WDGS on finishing performance and carcass characteristics 2) evaluate the effects of feeding different levels of beet pulp in combination with DRC or SFC, 3) compare grain adaption programs using beet pulp to a traditional grain adaption program with alfalfa hay on finishing performance and carcass merit and 4) determine the relationship between dietary S (rumen degradable and rumen undegradable), neutral detergent fiber and polioencephalomalacia (PEM). A WDGS x corn processing ratio interaction (P = 0.03) was observed for G:F. Cattle fed diets containing no WDGS with SFC as the sole source of corn had 11% greater G:F (0.189, P 0.01) compared to steers fed all DRC diets with no WDGS (0.170). As SFC replaced DRC in diets containing no WDGS, G:F increased quadratically (P 0.01). A positive associative effect in G:F was observed as SFC replaced DRC in diets with 0% WDGS; however G:F was not impacted by corn processing in diets containing 35% WDGS. Final BW, DMI, and ADG decreased linearly (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.

Book Description
The objective of this study was to evaluate the effects of feeding high protein corn distillers grains on fresh beef quality. Steers (n=300) were fed one of five diets (6 pens with 10 head/pen): a corn control, 40% high protein dry distillers grains plus solubles (HP-DDGS), 40% dry distillers grains plus solubles (DDGS), 40% wet distillers grains plus solubles (WDGS), or 40% bran plus solubles (Bran). Eighteen Choice carcasses (3 head/pen) were randomly selected within each treatment (n=88). Strip loins were aged for 2, 9, or 23 d, after which steaks were placed under retail display conditions for 0, 4, or 7 d. Dietary treatment had no effect on tenderness within each aging period (P > 0.05). After 7 d of retail display, following all aging periods, steaks from cattle fed HP-DDGS had the greatest discoloration except for DDGS and Bran after 23 d (P

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
With the large expansion of the ethanol industry in previous years, there has been an increase in supply of distillers grains plus solubles (DGS) for the feedlot industry. Distiller's grains are a common byproduct used in feedlot diets for added protein or energy. Recently, ethanol companies have been using different extraction techniques to remove various parts of the DGS to sell separately, such as corn oil and fiber. Previous research trials have tried to determine the contribution of individual nutrients in distillers grains that improve performance in order to predict the impact of removing certain components. In previous studies, fiber has shown the greatest contribution; however, no sole nutrient has been identified that contributes to providing equal performance to distillers grains. Therefore, a study was conducted to determine the value of the fiber in modified distillers grains plus solubles for finishing cattle performance. In that study, the conclusion was made that the isolated fiber component does not give equal performance to feeding MDGS due to a reduction in G:F and feeding value if only the fiber components replaced corn, which means the energy in MDGS is provided by other components to make it better than corn. Some producers are concerned that feeding de-oiled DGS will have a negative impact on finishing cattle performance. Currently, some feedlots have been adding corn oil back to diets to ensure they are getting the best performance possible. Although corn oil has been added to diets in the past and experiments have been done to evaluate de-oiled versus normal DGS, there has never been a study that evaluated the removal of corn oil from distillers grains compared to adding corn oil back to de-oiled distillers grains. Therefore, two finishing studies were completed to determine the effects of the removal of corn oil from modified distillers grains plus solubles and replacement with supplemental corn oil on finishing cattle performance and total tract digestibility. When corn oil was added back to MDGS, there was a negative impact on digestibility of OM and NDF as well as lower DE (Mcal/kg) compared with de-oiled MDGS or full fat MDGS. When 2% corn oil was added back to de-oiled MDGS, there was a 4.9% improvement in F:G compared to de-oiled MDGS. There was a numerical improvement in F:G by 3.7% for MDGS + Oil compared to FF MDGS.

Book Description
The main goal for a cow-calf producer is profitability, which requires optimum reproductive performance, while keeping feed costs low and ensuring that nutritional needs are met. Cow herds are grazed on pasture or crop residues, but these may not always meet nutritional requirements. Ethanol co-products such as dried distiller's grains with solubles (DDGS) and condensed distiller's solubles (CDS) may be supplemented to increase the energy and protein concentration of the diet. Recently it has been discovered that maternal diet can have long lasting effects on progeny growth and development. Thus, the effects of feeding the ethanol co-products DDGS and CDS to gestating or lactating beef cow performance and calf growth was investigated in several experiments. The hypothesis for this thesis was that feeding ethanol co-products to cows during gestation and/or lactation would improve cow performance and reproductive efficiency while improving the pre- and post-weaning growth of their calves relative to control diets that did not contain ethanol co-products. In the first experiment, cows with male progeny were fed isocaloric diets of DDGS or soybean meal (SBM) from calving until mid-lactation to determine the effect of DDGS on cow performance, milk composition and calf growth. Feeding DDGS increased conception (P 0.02) but not pregnancy rates (P = 0.64), did not alter cow BW (P ≥ 0.43), BCS (P ≥ 0.13) or milk production (P ≥ 0.75) but altered milk composition compared to diets that did not contain DDGS. Distiller's grains with solubles had no effect on short chain fatty acids (FA) in milk (P ≥ 0.13), but did decrease medium chain FA (P
