Analytical Methodology for Quality Standards and Other Attributes of DDGS

Distillers grains is the second largest processed feed ingredient in the United States, at an estimated 2010 production of 35 million tons (MT), with 9 MT going to exports (personal communication, Charles Staff, Distillers Grain Technology Council, Louisville, KY). As a feed ingredient, distillers grains are typically analyzed in laboratories for one of three purposes. This chapter is divided into three sections, accordingly: (1) for quality standards for trading purposes; (2) to determine nutrients for inclusion in livestock feeds; and (3) to determine contaminants that may limit inclusion in livestock feeds.
