True and Apparent Metabolizable Energy of Crude Glycerin in Betong Chicken

An experiment was conducted to determine the nitrogen-corrected true and apparent metabolizable energy (TMEn and AMEn, respectively) of crude glycerin (CG) for Betong chicken using a precision-fed rooster assay. A total of 15 male Betong chickens were assigned to three groups (0, 10, and 15% CG) of the experimental diet. Based on this experiment, CG supplementation enhanced the GE, TMEn, and AMEn of an experimental diet as the CG level was escalated. The TMEn and AMEn of CG were 3138 and 3046 kcal kg(-1) at 15% and 2977 and 2896 kcal kg(-1) at 10%, respectively.
