(A) ACE and Chao1 indices of bacterial diversity, Chao1 and ACE indices were significantly lower in the GT35 group compared to GT68 group, (B) Shannon and Simpson indices of bacterial diversity of GT35 and GT68 yak groups, Simpson indices did not show a significant difference among groups (p = 0.44), (p < 0.0001) = ***, (p < 0.001) = **, (p < 0.01) = *
