IntroductionThe rapid growth of the ethanol industry in the United States during the last decade has resulted in large quantities of ethanol coproducts in the marketplace, which are now commonly available as feed ingredients for livestock and poultry. These coproducts are often added to animal diets as sources of protein and energy. Mineral concentrations in the coproducts are also an important co ...

After fermentation, ethanol is separated by distillation while the water and non-fermentable materials (known as whole stillage) are decanted or centrifuged which results in wet cake (e.g., removed suspended solids) and soluble solid-laden water (i.e., thin stillage). Evaporation of the thin stillage produces condensed distillers solubles (known as CDS) which can then mixed into the wet cake, and ...

In this interview with Engormix, Kurt Rosentrater, Associate Professor at Iowa State University and Executive Director at the Distillers Grains Technology Council, answered questions about several important factors to take into account when using DDGS as a feed ingredient.Rosentrater deals with these topics and more on the recently released fifth edition of the book Kent’s Technology of Cere ...

Introduction The objective of this article is to briefly describe the most common ethanol coproducts, how they are produced, and typical nutrient compositions. Rapid growth of the ethanol industry in the United States over the last decade has generated large quantities of ethanol coproducts, which are now commonly available as feedstuffs for livestock. These coproducts are often added to live ...

Background The use of aquaculture feeds in Bangladesh has grown substantially in the past few years, and now over 1 million tonnes of commercial pelleted feed are being formulated for use by aquaculture farmers. An estimated further 0.4 million tonnes of locally-formulated and processed diets are also being prepared by small village-based feed-making enterprises. Rapid growth in use of formulated ...

Introduction Distillers grains (DG) originating from the corn-based fuel ethanol industry are an excellent source of energy and non-rumen degradable protein, and are an effective ingredient for dairy cattle diets. However, in spite of competitive price when compared to other protein sources and their high availability in the market, DG are not always sought as a dietary ingredient by some nutritio ...
