Figure 4.

The bacterial ASVs identified by LEfSe analyses were associated with dietary β-hydroxybutyric acid (BHB). A heatmap depicting the signature ASVs for each group identified by the LEfSe algorithm was drawn. The heatmap shows the average relative abundances of ASVs on a log scale. The color of cells from blue to red corresponds to the relative abundance of ASVs from low to high. C90 = controls at 90 days of age; L90: low dose (3 g/d per animal BHB) at 90 days of age; M90: medium dose (6 g/d per animal BHB) at 90 days of age; H90: high dose (9 g/d per animal BHB) at 90 days of age.
