Rarefaction curves of alpha diversity among groups.
(A) average observed_OTUs at 97% of similarity and (B) average Chao1; Control: normal feed, T1: normal feed with 0.2% Biolex® MB40 and T2: normal feed with 0.2% Leiber® ExCel.

Beta diversity analysis among groups.
(A) weighted and (B) unweighted UniFrac PCoA plots of individual birds in each group. Individual sample was represented as spot with red (C; normal feed), blue (T1; normal feed with 0.2% Biolex® MB40), and orange (T2; normal feed with 0.2% Leiber® ExCel).
Fig 3.
Comparison of top 6 cecal bacteria among groups in a phylum level.
Blue, red, and green bars stand for T1 (normal feed with 0.2% Biolex® MB40), T2 (normal feed with 0.2% Leiber® ExCel), and control (C; normal feed), respectively. Capital letters on the top of bar within each phylum level indicate significant differences among groups (P < 0.05). N.S. (not significant).
Fig 4.
Comparison of top 7 cecal bacteria among groups in an order level.
Blue, red, and green bars stand for T1 (normal feed with 0.2% Biolex® MB40), T2 (normal feed with 0.2% Leiber® ExCel), and control (C; normal feed), respectively. Capital letters on the top of bar within each order level indicate significant differences among groups (P < 0.05). N.S. (not significant).
Fig 5.
Overall cecal microbiota compositions of each sample with a family level.
The 15 samples from left are T1 (normal feed with 0.2% Biolex® MB40), 15 samples in the middle are T2 (normal feed with 0.2% Leiber® ExCel) and next 15 samples are control (C; normal feed), respectively.
Fig 6.
Overall cecal microbiota compositions of each sample with genus level.
The 15 samples from left are T1 (normal feed with 0.2% Biolex® MB40), 15 samples in the middle are T2 (normal feed with 0.2% Leiber® ExCel) and next 15 samples are control (C; normal feed), respectively.
