DDGS in poultry nutrition
The majority of by-products produced by the dry-grind ethanol industry are dried distillers grains with soluble. The DDGS from different sources like corn, rice, wheat, sorghum are highly useful for livestock and poultry. Among that corn DDGS is an excellent feed ingredient for use in layer, broiler, duck and turkey diets and contains approximately 85% of the energy value in corn, has moderate levels of protein and essential amino acids, and is high in available phosphorus. With growing demand for food and scarce resources, the animal livestock industry doesn’t have the luxury of letting anything go to waste. Corn by-products (DDGS) from the ethanol industry are considered to be waste, but can still have a use as a feed ingredient. Because it is considered a waste product it is a very cheap source of crude protein, crude fibre, available phosphorous, unsaturated fatty acids and essential amino acids. It is an effective replacer of soya and corn in the poultry diet with the added benefit that it reduces feed costs.
Introduction After the fermentation process of corn to produce ethanol, the remaining fat in the by-product distiller’s dried grains with solubles (DDGS) is extracted by centrifugation. The resulting by-product is known as low-fat DDGS, which has slightly higher protein content, amongst other nutrients, compared with conventional DDGS (Kshun and Kurt, 2012). The fat extraction in low-oil DDGS reduces its xanthophyll...

Introduction The use of exogenous proteases in poultry diets has gained momentum during the last decade. The first commercial protease was introduced into the poultry feed market in the 1990s in combination with other enzymes, with the aim to increase the energy and protein digestibility of grain and oilseed meal based diets (Simbaya et al., 1996). A number of proteases are now...

Introduction Fuel ethanol production is one of the fastest growing segments in American agriculture. Currently, there are 92 ethanol plants in production, with an additional 23 ethanol plants under construction (www.ethanolrfa.org/industry/statistics, November, 2005). These ethanol plants will have production capacity of 5.6 billion gallons of ethanol per year (Renewable Fuels Association, November, 2005). Approximately...

Held every other year by the U.S. Grains Council (USGC) and Renewable Fuels Association (RFA), Export Exchange brings together international buyers and U.S. sellers of distiller's dried grains with solubles (DDGS), as well as other feed grain products. The 2016 event is expected to attract nearly 500 attendees, including 200 from 30 countries participating as part of USGC trade teams.

Introduction Dried distillers grains with solubles (DDGS) are a by-product of the spirit industry and of bioethanol production. They are obtained as a result of multi-stage concentration, and then, long-lasting drying of cereal mash, earlier deprived of ethyl alcohol. These products are constituted by components from initial raw material, being insensitive to fermentation (non-starch carbohydrates, protein, fat, ash and others), and biomass of...

INTRODUCTION When attributional life cycle assessment (LCA) is used to calculate the greenhouse gas (GHG) intensity of corn ethanol the consequences of feeding by-products from ethanol production (DDGS) must be taken into account. Current LCA approaches assume that there are fixed ratios for substituting by-products for a few feed ingredients. This assumption is only partially correct due to the dynamics of the animal feeding industry. ...

A study was conducted to evaluate effect of high levels of corn DDGS and rye on growth performance and gut health of broilers as influenced by a nonstarch polysaccharides (NSP) degrading enzymes blend (CIBENZA ® CSM, Novus International, Inc.). The study consisted of 8 treatments: corn soy control, 30% DDGS, 16% corn bran, 38% rye, 38% rye plus enzyme, 25% rye, 25% rye 30% DDGS, and 25% rye 30% DDGS plus enzyme. Corn bran...

Distillers´ dried grains with solubles (DDGS) are increasingly becoming important in poultry feeding. Research into the use of this material has focused largely on maize DDGS from North America and less work has been done on the predominantly sorghum DDGS that are produced in Australia. In preliminary tests, we investigated the variation in nutrient composition of sorghum DDGS and then conducted a feeding trial on broiler chickens. The trial involved 432...

Today, by-products of ethanol production like corn distillers dried grains with solubles (DDGS) are being used in livestock feeds. Largely due to economics and availability, we have seen more DDGS fed each year for the past three years. Research studies have investigated DDGS inclusion rates up to 40% of finishing diets and most have settled within a range of 5-15% inclusion rate to commercial flocks. In the early days of ethanol production, we faced much...

Rovabio ® , the versatile enzyme from Adisseo, has a proven efficacy on wheat and corn distillers dried grain with solubles (DDGS) on broilers. We evaluate that the metabolizable energy uplift with Rovabio ® Excel is about 5.5 % for corn DDGS and 7.5% for wheat DDGS.
The significant levels of cellulase and xylanase in Rovabio ® allow for breakdown of the increased...

Cornbelt agriculture has benefited from the ethanol market that will consume an estimated 3.7 billion bushels of corn this marketing year, and has created a premium pricing environment for the corn grower. 2009 will produce an estimated 11 billion gallons of ethanol, enroute to the 2015 mandate of 15 billion gallons. But along with the explosive growth in ethanol has been a similar growth in production of distiller's dried grains, expected to reach 40 million tons this year. But what is the...

The rapid emergence of ethanol plants in Indiana will result in a large quantity of corn co-products that could be used to feed poultry. The primary co-product available is fed as dried distillers’ grains with solubles (DDGS); however, the quantity that may be fed may be limited because there are numerous issues affecting use of DDGS in poultry rations. Issues to Be Addressed Whether large amounts of DDGS can be fed on poultry farms...

The increased use of corn for ethanol production has contributed to a sharp increase in corn prices, translating into higher feed costs for livestock and poultry producers. Yet one way producers can benefit from the ethanol industry is to incorporate ethanol by-products into feed rations. Several researchers at Iowa State are studying the use of dried distillers grains with solubles (DDGS) as a feed ingredient. A recent project showed laying hen diets can be formulated with high amounts...
