Values are means ± SEM, n = 3/treatment. 1 Analytical results obtained according to AOAC (AOAC, 2007). Values are means ± SEM, statistical significance was considered at p < 0.05. Crude fiber, neutral detergent fiber, acid detergent fiber, crude fat, starch, crude protein contents and amino acids were measured on an 88% dry matter basis.
