An aliquot of 500 g was removed and dried in an oven with forced ventilation at 60°C for 72 h for further analysis and calculation of nutrient digestibility of DM, CP, ether extract (EE), crude fiber (CF), crude ash (CA), and nitrogenfree extract (NFE). To determine the value for NFE,
the formula NFE = 100 − (CF + EE + CP + CA + moisture) was used
