Figure 2.

Comparison of dominant bacteria genera and species of sika deer at velvet antler growth stage under different selenium levels. Note: The three vertices in the figure represent the three sample groups, and the circle represents the species. The size of the circle is proportional to the relative abundance. The closer the circle is to a vertex, the higher the content of the object in this group. (A,B) is the comparison of dominant bacteria at genus level. (C,D) is the comparison of dominant bacteria at species level.
