Amino Acid Digestibilities of DDGS

Five samples of distillers dried grains with solubles (DDGS) were collected and evaluated for energy and amino acid digestibilities using a precision-fed rooster assay.  The Ohio State University study suggested that DDGS samples with darker color scores had lower amino acid and energy digestibilities.  These results suggested that overheating during drying may cause Maillard reactions and lower total lysine, lysine digestibility and total metabolizable energy values.  (Comment- Bottom line is the need to carefully characterize the DDGS source prior to diet formulation).
