The composition of the diets was obtained by feed analysis (AOAC, 2005), followed by the procedures of determination of DM (method 976.05), CP (method 976.05, N×6.25) and ash content (method 942.05). For NDF analysis, samples were treated with alpha amylase at a stable temperature without the addition of sodium sulfite and corrected for ash (Mertens et al., 2002). The EE analysis was conducted by the Soxhlet extraction (method 920.39).
