  1. SGMT clade: M. smithii, M. gottschalkii, M. millerae and M. thauerii, RO clade: M. ruminentium and M. olleyae
  2. Other 8 OTUs are the OTU 8, OTU 9, OTU 10, OTU 11, OTU 12, OTU 13, OTU 14, OTU 15
  3. In the same row, values with different letter mean significant difference (FDR-P < 0.05)
  4. BD Basal Diet, BDP Post-control period, SEM Standard error of the mean
  5. KW_P values were the overall significant differences analyzed using Kruskal-Wallis test for the non-normally distributed data
