Book Description
The main objective of this project was to investigate the effects of the type of dried distillers grains with solubles (wheat DDGS, corn DDGS, and blend DDGS (eg. wheat:corn = 70:30)) and bio-ethanol plant origin on the nutrient variation and availability in ruminants. In addition, DDGS products were studied as opposed to their parental grains. The project was divided into the several following studies. In Study 1, we studied the nutritive value of DDGS products in terms of (1) chemical profiles, (2) protein and carbohydrate sub-fractions associated with different degradation rates, and (3) digestible component nutrients and energy values using the NRC 2001-chemical approach and the in situ assay-biological approach. Also, we tested the validity of acid detergent insoluble crude protein (ADICP) and acid detergent lignin (ADL) to predict the potential degradability of DDGS. Due to starch fermentation in the ethanol process, the chemical components in DDGS became approximately threefold more concentrated than in feedstock grains. Slowly degraded protein (PB3) and unavailable protein (PC) increased in DDGS, indicating a decrease in the overall protein degradability in the rumen. Intermediately degraded protein (PB2) was higher for corn DDGS than for wheat DDGS and blend DDGS (54.2 vs. 27.7 vs. 30.8 %CP), while PB3 was higher for wheat DDGS and blend DDGS (29.9 vs. 51.2 vs. 53.2 %CP). Mainly as a result of differing heat conditions, PC differed significantly between wheat DDGS originated at different bio-ethanol plants (0.7 vs. 7.6 %CP). The prediction of truly digestible CP (tdCP) and NDF (tdNDF) differed between the NRC 2001-chemical approach and the in situ assay-biological approach; however, both approaches reported similar energy values. These values were the highest for corn DDGS (DE3X: 3.9 Mcal kg-1), followed by blend DDGS (DE3X: 3.6 Mcal kg-1), and wheat DDGS (DE3X: 3.4 Mcal kg-1). Corn DDGS was superior to corn, wheat DDGS was similar to wheat and corn, and bl.

Book Description
"Increasing bio-fuel production in the future will have a major impact on the feed industry. Not only will the competition for food, fuel and feed decrease the availability of feedstuffs for animal production but, also new feedstuffs will become available for which the nutritional quality needs to be reviewed. The nutritional value and usability of the by-products as feedstuffs will be the main focus of the book. In particular, rapeseed meal and glycerine from biodiesel production and DDGS from bioethanol production are discussed. For each product comprehensive research data summarising the variation in quality and production systems, the energy and protein value for each animal category and the effects on animal production are presented. Additionally, this book gives an overview of the current and future developments of the emerging bioenergy production. Broad topics which are addressed are: the global potential for bioenergy production, the enormous increase in bioethanol production in the U.S. against the backdrop of a developing bioethanol production in the EU and the future effects on supply and demand of the grain and feedstuff market. This book will update nutritionists, researchers, traders and those working in the allied industry on the current 'state of knowledge' of the usability of the different by products from biofuel production in specific animal feeds."

Book Description
Biorefineries are an essential technology in converting biomass into biofuels or other useful materials. Advances in Biorefineries provides a comprehensive overview of biorefining processing techniques and technologies, and the biofuels and other materials produced. Part one focuses on methods of optimizing the biorefining process and assessing its environmental and economic impact. It also looks at current and developing technologies for producing value-added materials. Part two goes on to explore these materials with a focus on biofuels and other value-added products. It considers the properties, limitations, and practical applications of these products and how they can be used to meet the increasing demand for renewable and sustainable fuels as an alternative to fossil fuels. Advances in Biorefineries is a vital reference for biorefinery/process engineers, industrial biochemists/chemists, biomass/waste scientists and researchers and academics in the field. - A comprehensive and systematic reference on the advanced biomass recovery and conversion processes used in biorefineries - Reviews developments in biorefining processes - Discusses the wide range of value-added products from biorefineries, from biofuel to biolubricants and bioadhesives

Book Description
In order to successfully compete as a sustainable energy source, the value of biomass must be maximized through the production of valuable co-products in the biorefinery. Specialty chemicals and other biobased products can be extracted from biomass prior to or after the conversion process, thus increasing the overall profitability and sustainability of the biorefinery. Biorefinery Co-Products highlights various co-products that are present in biomass prior to and after processing, describes strategies for their extraction , and presents examples of bioenergy feedstocks that contain high value products. Topics covered include: Bioactive compounds from woody biomass Phytochemicals from sugar cane, citrus waste and algae Valuable products from corn and other oil seed crops Proteins from forages Enhancing the value of existing biomass processing streams Aimed at academic researchers, professionals and specialists in the bioenergy industry, Biorefinery Co-Products is an essential text for all scientists and engineers working on the efficient separation, purification and manufacture of value-added biorefinery co-products.

Book Description
Growth in corn dry-mill ethanol production has surged in the past several years, simultaneously creating a co-product distillers' grains (DDGS). Many in the U.S. feed industry were concerned about the size of this new feed source and whether it could be used entirely by the feed industry, but they also worried about the price discovery process for the product. Provides a transparent methodology to estimate U.S. supply and consumption of DDGS. Potential domestic and export use of U.S. DDGS exceeds current production and is likely to exceed future production as ethanol production continues to grow. Identifies the DDGS price discovery process along with the price relationships of distillers' grains, corn, and soybean meal. Illus. A print on demand report.
