^aThe taxonomic classification, the mean relative abundance and the log₂ fold change (BBR/Control) of the LinDA normalized abundance of each genus are shown. Only genera with P < 0.05 and |log₂ fold change| >1.5 were considered biologically relevant and were included. No differentially abundant genera (P < 0.05) were found in the jejunum or the ileum.
