| Two experiments were conducted to determine the net energy (NE ) of wheat-corn distillers dried grains with solubles (wcDDGS ) using the comparative slaughter (CS), the indirect calorimetry (IC) and the chemical composition (CH) methods. Based on the CS method, NE values of 2,407, and 2,424 kcal/kg DM were obtained for wcDDGS included at 15% and 30%, respectively. For the IC method, the NE values of 2,407, and 2,403 kcal/kg DM were obtained for wcDDGS included at 15% and 30%, respectively; corresponding values for the CH method were 2,536 and 2,197 kcal/kg DM, respectively. It is concluded that NE value of wcDDGS ranges from 2,367 kcal/kg DM to 2,416 kcal/kg DM depending on the method used. As the values obtained from the various methods were not different, the average NE value for the wcDDGS evaluated was 2,396 +/- 25.71 kcal/kg DM. |
