Logarithm (ln) value changes promoted in treatment contrasts (adjusted P < 0.05) in family taxa in the caecal microbiota. CTR, control diet; XYL, CTR supplemented with xylanase at 16,000 birch xylan units/kg; XYL + LY, XYL supplemented with live yeast (2 × 10¹⁰ CFU/g) at 1 kg/t. Positive values and negative values indicate greater and lower abundance based on the absolute operational taxonomic units, respectively. Differences presented are based on all taxa detected in samples per treatment.
