  1. Log10DNA gene copies of all bacteria, Firmicutes, Bacteroidetes, Lactobacillus spp., Enterococcus spp., Streptococcus spp., Clostridium cluster I, Clostridium cluster IV, Clostridium cluster XIVa, Bifidobacterium, Enterobacteriaceae, and in the jejunum, and ileum, respectively. Log10DNA gene copies quantification data were normalized to the standard curve lines and presented with the mean ± standard deviation (n = 6)
  2. Superscript letters a, b, c, and d represent (P < 0.05) between the group and NC group, SNE group and BS15, respectively
