Modulation of L–malic acid on the constitution of gut microbiota in sows during late pregnancy by 16S rRNA sequencing: (A,B) shows the relative abundance of the bacteria community at the phylum and genus level, respectively; (B) displays the top 20 abundant genera; and (C) shows the communities with significant differences in relative abundance at genus level. CON, basal diet; MA, basal diet containing 2% L–malic acid complex. Data are presented as mean ± SEM (n = 6). Statistics were performed with Student’s t-test. * p < 0.05.
