Bacterial core microbiome. a Average difference in the relative abundance of OTUs observed in bacterial core microbiome for barley (orange), oat (blue), triticale (green) and intercropped (red) fresh forages as compared to terminal silages (0 to 90 day) (n = 3). Bacterial orders that exhibited variation ≤ to 1% are not shown. Members of the Lactobacillales are presented separately to ease interpretation. b Average difference in the relative abundance of OTUs observed in bacterial core microbiome for barley (orange), oat (blue), triticale (green) and intercropped (red) silages after 14 days of aerobic exposure (90 to 104 days) (n = 3). Bacterial orders that exhibited variation ≤ to 0.05% in all silages are not shown. Xanthomonadales, Bacillales and Lactobacillales are presented separately to ease interpretation
