Nutritive value of corn distillers dried grains with solubles as an ingredient of poultry diets: A review

Abstract

A rapid increase in corn use in ethanol plants, and subsequent creation of distillers dried grains with solubles (DDGS) by-products, has led to an increase in the use of DDGS in the diets of livestock. DDGS has been used all over the world as a dietary ingredient and this has necessitated more research to be conducted on its quality, nutritive values, and recommendations for feeding to poultry. Currently, there have been a limited number of research publications regarding corn DDGS as an ingredient of diets for poultry. Approximately 100 scientific papers can be found which cover a variety of topics, with various degrees of depth into each. The purpose of this review is to collate the available information to date on the application of corn DDGS as an ingredient of poultry diets that can be easily accessed by researchers and nutritionists. This review presents the current state of knowledge of nutritive values of various corn DDGS ingredients, summarizes recommendations for using DDGS in diets for laying hens, broilers and turkeys, and reports the environmental ramifications when utilizing corn DDGS in poultry feed. In spite of the great amount of variation in nutritional properties of corn DDGS originating from various sources, it has been concluded that good quality corn DDGS, especially when derived from new generation plants, can be a viable ingredient in poultry diets.Corn distillers dried grains with solubles (DDGS) is a by-product of ethanol production plants that use corn for manufacturing (Aines et al., 1986). During yeast fermentation in ethanol plants, corn is ground, mixed with water, cooked and the liquefied starch from this process is hydrolysed and fermented to produce ethanol and CO 2 (Rosentrater,

By-product Originating from Artisan Distillers of Rice Alcohol in Northern Vietnam: Production, Use and Nutrient Value for Smallholder Pig Raising

“…Thus, the average values of calcium, phosphorus, copper, iron, manganese and zinc in RDP of present study are increased between 2 and 9 times in comparison with value of brown rice. The results of this study are in agreement with previous studies [4,5,6,21] who indicated that most mineral contents of DDGS are at least 3 times higher than those of the grain from which it originated. In the present study, average phosphorus content in the rice distiller's by-product samples analysed was within the range of published values in DDGS of previous reports [4,5,6,19,20,21].…”

In the present study, average phosphorus content in the rice distiller's by-product samples analysed was within the range of published values in DDGS of previous reports [4,5,6,19,20,21]. Calcium level in RDP was lower than in DDGS as reported by previous studies [19,20] or slightly higher [4,5].…”

“…Difference among chemical composition of RDP in the present study when compared to previous studies is probably ascribed, as for DDGS, by input materials, distillation equipment and production process [4,5].…”

“…In developed countries, dried distillers grains with solubles (DDGS) -a cereal byproduct from ethanol production plants -are used as animal feed [1,4,5,6]. They contain high levels of crude protein (27.15%), phosphorus (0.76%) and other nutrients [5] while their price is about half to a quarter lower than that of soybean meal and fish meal respectively.…”
