The average degree of polymerisation (avDP) of water-extractable arabinoxylan (WE-AX) at the level of the ileum (A) and caeca (B) for broilers fed the control diet or endoxylanase supplemented diets Bel10, Bel100, Bel1000, Eco10, Eco100 and Eco1000 at 11 and 36 d of age. ^{∗, ∗∗} indicate treatment means which differ significantly at P ≤ 0.10 and P < 0.05, respectively from the control mean; analysed according to the posthoc Dunnett's test (n = 5). Capital letters A, B indicate a significant difference for the effect of endoxylanase preparation at a particular broiler age (Bel vs. Eco) (P < 0.05, interaction age × enzyme). Small letters a, b, c in white circles denote a significant difference for dose (10 vs. 100 vs. 1,000 mg/kg) at a particular age and endoxylanase preparation (P < 0.05, interaction age × dose and enzyme × dose). The arrows denote a significant overall age difference (P < 0.05). Error bars denote the standard error of the represented means (SEM).
