^a–cDifferent superscripts within the column “Age (D)” have significant age differences for each parameter (main effect of age, P < 0.05).

^y,zDifferent superscripts within the column “Diet” have significant dietary treatment differences for each parameter (main effect of diet, P < 0.05).

Abbreviations: AXOS, arabinoxylan-oligosaccharides; NS, not significant.

Reported values of the substitution ratio A to X are means of 10-12 replicates (N = 10–12) for the main effect of age and 25 to 30 replicates (N = 25–30) for the main effect of diet.
