Ethanol Co-Product Use in U. S. Cattle Feeding

ISBN: 1437921744

Pages : 14
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.

Impact of Ethanol Process Changes on Distillers Grains for Beef Cattle

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.
Impact of Ethanol Expansion on the Cattle Feeding Industry

Book Description
The U.S. has a history of producing surplus corn, but the current and projected growth in ethanol production combined with strong feed and export demand is causing an overall increase in corn utilization. Although livestock feeders are projected to remain the largest users of corn, corn utilization can be reduced if ethanol co-products are used to replace a portion of corn in finishing rations. The objective of this study was to determine the economic trade-offs for cattle feeders when facing higher corn prices and increasing supplies of ethanol co-products. A stochastic partial budget model was used to determine the impact on the cost of gain when ethanol co-products are substituted into rations at varying inclusion rates. The model was built for all four major cattle feeding states: Texas, Nebraska, Kansas, and Colorado. Ration scenarios were developed for each state, based on the research results of feedlot nutrition and personal communication with feedlot operators. The various scenarios were simulated to determine the impacts of changing corn prices, corn processing costs, cattle performance, and feeding and transportation costs for Wet Distiller's Grains with Solubles (WDGS) on the key output variable, cost of gain. The model results indicated when 15 percent WDGS (on a dry matter basis) replaces a portion of corn and protein supplement, the simulated cost of gain is lower than the base ration scenario when the feedlot is located within 200 miles of ethanol production. When feedlots are located more than 200 miles from an ethanol plant, Dried Distiller's Grains with Solubles (DDGS) can be fed to lower the cost of gain; therefore, ethanol co-products can be fed to help offset potential increases in corn prices. The partial budget model is a useful tool for livestock, corn, and ethanol producers who are attempting to determine the impacts of ethanol expansion on corn price and utilization. Policy makers can also benefit from the model analysis as they face decisions in the future regarding ethanol and farm policy alternatives.
Nutrient Requirements of Beef Cattle

Book Description
As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.
Economic Research on Ethanol Feed-Use Coproducts

Book Description
During the domestic ethanol boom of the mid-2000s to early 2010s, ethanol coproducts grew to play a crucial role in both ethanol plant profitability and livestock feeding rations. Coproducts from ethanol production have risen from providing a single additional revenue stream to diversified value-added product offerings to increase revenue and thus maintain profit margins. The objective of this paper is to provide a comprehensive review of the economic research on feed-use ethanol coproducts. Existing research finds that traditional feed use ethanol coproducts, consisting largely of distillers' grains products, positively contribute to the livestock feeding industry, especially in their ability to offset the impacts on the grain markets brought on by increased ethanol production. However, much of the research covered appeared during the ethanol boom of the first decade of the 2000s. The market has continued to evolve introducing de-oiled products, corn oil, and high protein distillers has left many current economic questions in the distillers' grains industry unexplored. Very little work has been conducted on non-feed-use products. The physical market has moved well beyond the current academic understanding of market products and structure. Based on this, we provide suggestions for future economic research for value-added distiller grains, government regulation, and different commodities and locations.
