Purpose and Scope

The purpose of this Standard is to summarize what is known about the physical properties of DDGS. This encompasses values for key properties and their known ranges. This information is needed by agricultural and other engineers and technologists who design and build storage structures as well as also material handling and processing equipment for DDGS, at both the commercial and the farm scale.

Distillers dried grains with solubles (DDGS) is a coproduct of the fuel ethanol and distillery industries, and has become a highly-valued livestock feed. Most of the DDGS in North America comes from manufacturing plants that convert corn into ethanol for oxygenated motor fuels.

This standard should be used as a reference document only. Although typical ranges for various properties are provided, it should be noted that the properties of DDGS can exhibit substantial variation among ethanol production plants, as well as over time within a given plant, due to differences in processing equipment, techniques, and raw materials used.

This Standard is compatible with coproduct definitions provided by the American Association of Feed Control Officials (AAFCO) and the 2007 AFIA Sub-Working Group.
