Bacterial alterations that contribute to enzyme shifts after fermentation in different groups. CK, Control (samples without inoculants); BA, samples inoculated with Bacillus amyloliquefaciens; BS, samples inoculated with Bacillus subtilis. Arabic number indicating days of ensiling. Summary of enzyme shifts predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt2). Significant differences of the 3 enzymes among the three groups with the same silage period at P < 0.05
