Changes of ileal microbiota in 60-day-old Hu lambs. A: Shannon curve; B: β-diversity analysis (PCoA); C: Chao index; D: Shannon index; E: Relative abundance of the lambs’ ileal microbiota in level phylum; F: Relative abundance of the lambs’ ileal microbiota in level genus; G: Random forest analysis; H: LEfSe analysis between the Con group and Pro group (LDA threshold = 3.0); I: LEfSe analysis between Con group and Syn group (LDA threshold = 3.0). *P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001
