Effects of finely ground wheat bran on fecal microbiota composition of sows. (A) OTU Venn of 3 dietary treatments. (B) Percent of community abundance at the phylum level, the results were analyzed by Student's t-test and presented as mean values of different bacteria, n = 6. (C-a) The difference of microbiota at the class level. (C-b) The relative abundance of Clostridia in different groups. (D-a) The difference of microbiota at the order level. (D-b) The relative abundance of Lachnospirales in different groups. (E-a) The difference of microbiota at the genus level. (E-b) The relative abundance of norank_f_p-2534-18B5_gut_group in different groups. The results of (C-a), (D-a), and (E-a) analyzed by Kruskal–Wallis H test, n = 6; the y-axis represents the microbiota name at a certain classification level; the x-axis represents the average relative abundance in different groups of species; and the columns with different colors represent different groups. The rightmost is the P-value, ∗P ≤ 0.05. (C-b), (D-b) and (E-b) The x-axis represents different samples; columns of different colors represent different groups; and the y-axis represents the abundance proportion of a microbiota in different samples. OTU = operational taxonomic unit.
