Effects of natural capsicum extract (NCE) on the microbiota communities in colon digesta of weaned pigs. Key phylotypes of microbiota communities in colon digesta of weaned pigs fed basal diet as control (CON, noted in red), basal diet with chlortetracycline (CTC, noted in blue), and basal diet with NCE (noted in green) were shown using LEfSe analysis via the Kruskal–Wallis rank sum test to measure the significant difference. LDA scores (threshold: ≥2) was used to determine the effect size. LDA = linear discriminant analysis. The CON had no significant different microbiota community compared with CTC and NCE, so CON was not shown in the figure.
