Interpretive Summary: Many research studies have examined chemical properties and nutritional characteristics of DDGS, especially in terms of utilization as livestock feed ingredients, their digestibilities, and resulting animal performance. Up until just a few years ago, however, no information was available regarding the physical properties of DDGS. But that is beginning to change, though, as more research is being conducted and published. The scientific understanding of DDGS is increasing, and this chapter aims to encapsulate this knowledge. The objective of this chapter is to discuss what is currently known about the physical attributes of DDGS. Specifically, this chapter will provide typical ranges for DDGS properties (including various physical and flow properties), definitions of these properties, and will review relationships among soluble solids, moisture, and lipids, how these influence the nature of particle surfaces and resulting frictional properties, and ultimately how all of these affect flowability.
