Taxonomic composition of the cecal microbiota of broilers on d 28 at A) phylum level, and B) at family level in different treatments. ‘Others’ refer to the minor bacterial phyla whose average relative abundance were < 1%. R1–R5 represents replicate samples from each experimental unit. The control is no injection treatment group. “Unclassified” refers to those bacterial taxa that were only assigned at a higher taxonomic level. The column labels R1–R5 denote replicate samples in each treatment
