The synergistic effect of dietary microbial muramidase and precision biotics on the ileum mucosa microbiota of broilers on d 35. Principal coordinate analysis: A Bray Curtis and B unweighted UniFrac. T1: negative control groups, NC (basal diet); T2: positive control groups, PC (basal diet supplemented with 0.1% probiotics); T3: muramidase groups, MR (basal diet supplemented with 0.035% microbial muramidase); T4: precision glycan groups, PG (basal diet supplemented with 0.1% precision glycan); T5: mixture of MR and PG group, MRPG groups (basal diet supplemented with 0.025% microbial muramidase + 0.1% precision glycan)
