Use of Distiller´s Dried Grains with Solubles (DDGS) from corn or wheat in broiler diets

Abstract

The production of grain-based bioethanol is increasing due to the rising demand for biofuels and the global decline in fossil fuel sources. Distiller’s dried grains with solubles (DDGS) from corn or wheat are the main by-product of bioethanol fermentation, primarily through dry milling technology, and have been used as low-cost animal feed. With the increase in ethanol production from grains, the production of DDGS from corn or wheat also increases. Several studies have found that DDGS has high nutritional value but variable composition, and researchers have found ways to enhance its quality and safety. Various approaches have been proposed to improve the digestibility and nutritional value of DDGS. However, despite its high nutritional value, DDGS has not yet been fully studied and is less utilized in broiler feeding. The benefits and risks associated with the use of DDGS have been studied for a long time, but more research is needed to establish quality and safety standards for DDGS. This review aims to highlight the challenges of using DDGS in broiler chicken nutrition.
