Fig. 8
A heatmap showing the log10 relative abundance of significantly different cecal microbes in different treatments compared with no injection control in broilers at d 28 post-hatch. The value of abundance is denoted by the color of the heatmap, and the values are represented in the legend, where the light green color denotes the lower abundance while the blue color denotes higher abundance. The yellow asterisks in the cell indicate a statistically significant treatment compared to the no injection control for the bacterial species in the row (*P ≤ 0.05). The dendrogram is generated by the Euclidean distance method and represents the clustering of bacterial species. The column labels R1–R5 denote replicate samples in each treatment. NSC: normal saline, XOS3: xylotriose, XOS4: xylotetraose, MOS3: mannotriose, MOS4: mannotetraose, NIC: no injection control
