2Content per kg of Alfalfa Powder: 90.47% DM, 6.11 MJ/kg DE, 16.02% CP and 27.35% CF.
3Content per kg of premix: 5320 mg of FeSO4.H2O, 1080 mg of CuSO4.5H2O, 560 mg of MnSO4.H2O, 3652 mg of ZnSO4.H2O, 1000 mg of CoCl2.6H2O, 180,000 IU of vitamin A, 18,000 IU of vitamin D and 900,000 IU of vitamin E.
4All values represent the measured values except for DE. DE was calculated by using known DE values for basal diet ingredients.
