What is the energy concentration value given for Dried Distillers Grains (DDG)?

• A. 2.01
• B. 1.37
• C. 1.97
• D. 0.48

Answer: (C)

Energy concentration is the energy available from a feed per unit of mass. For Dried Distillers Grains, standard feed tables assign about 1.97 Mcal of energy per kilogram of dry matter. This reflects DDG’s relatively high energy density due to its fat content compared with other feeds. The value 1.97 Mcal/kg DM is the commonly cited figure used in formulation and testing, making it the best answer. The other numbers do not match the established energy density listed in typical references.
