The temporal dynamics of rumen microbiota from the stocker to the finishing stage. A The Shannon index of rumen microbiota. The significance among sampling time points was labeled with different letters. B Principle Coordination Analysis (PCoA) of Bray-Curtis distances for microbiota. C Bacterial abundances at the genus level. Each bar represents a bacterial genus, and each column represents one sample. Ruminal fluids were collected on d 0, 28, 85 (S0, S28, S85) during the stocker phase and on d 0, 14, 28, 56, starting to add Pre-Ba (30 d before harvest) and at the end of finishing stage (F0, F14, F28, F56, Pre-Ba, and Final) during the finishing stage
