With the rapid growth in the fuel ethanol industry in recent years, considerable research is being devoted todetermining distillers dried grains with solubles (DDGS) nutritional properties and to optimizing their inclusion in livestockdiets; physical properties of these materials, however, have been largely ignored. Using standard laboratory methods, severalphysical properties for typical DDGS streams were determined, including moisture content, water activity, thermal properties(conductivity, resistivity, and diffusivity), bulk density, angle of repose, and color. The DDGS samples in this study weregolden-brown in color and exhibited physical properties similar to other dry feed ingredients, such as hominy feed, corn glutenfeed, and other corn-based materials. As a first step, the numerical data generated during this study will help fill a currentvoid in design information for the ethanol and livestock industries.
