Water-extractable arabinoxylan (WE-AX) and total arabinoxylan (TOT-AX) digestibility (%) at the level of the feces analyzed at 6 different broiler ages (day 5, 10, 15, 21, 28, and 35) for broilers fed a control (CTRL) and a 0.50% arabinoxylan-oligosaccharides supplemented (AXOS) wheat-based diet. Lowercase alphabets a,b and asterisk (*) denote significant differences between dietary treatment means at a particular age (interaction effect between diet × age, P ≤ 0.05 and P ≤ 0.10, respectively).
