The effect of PCA on cecal microbial community. a Principal component Analysis ordination plots of microbial communities in the CTL, AUR and PCA group based on the Bray-Curtis distance metric. b Analysis of similarities (ANOSIM) between CTL, AUR and PCA group. c The effect of PCA on the chao1 index. d The effect of PCA on the Shannon index. CTL, a basal diet; AUR, a basal diet containing 50 mg/kg aureomycin; PCA, a basal diet supplemented with 0.4% protocatechuic acid. Data were shown as means ± SD (n = 6), *P < 0.05 compared with CTL
