The average concentration of GE in DDGS is approximately 5,434 kcal per kg DM. this value is greater than the concentration of GE in corn. However, the digestibility of energy, measured as percent of GE, is lower in DDGS than in corn, and the measured concentrations of DE and ME in DDGS are 4,140 and 3,897 kcal per kg DM, respectively (Pedersen et al., 2007).
