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

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
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
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
Frontiers in Bioenergy and Biofuels presents an authoritative and comprehensive overview of the possibilities for production and use of bioenergy, biofuels, and coproducts. Issues related to environment, food, and energy present serious challenges to the success and stability of nations. The challenge to provide energy to a rapidly increasing global population has made it imperative to find new technological routes to increase production of energy while also considering the biosphere's ability to regenerate resources. The bioenergy and biofuels are resources that may provide solutions to these critical challenges. Divided into 25 discreet parts, the book covers topics on characterization, production, and uses of bioenergy, biofuels, and coproducts. Frontiers in Bioenergy and Biofuels provides an insight into future developments in each field and extensive bibliography. It will be an essential resource for researchers and academic and industry professionals in the energy field.
