Effects of EO + OA on the diversity of gut microbiota in weaned piglets. (A-E) are alpha-diversity analyses for ACE index, Chao1 index, observed_species index, goods_coverage index, and Simpson index (n = 6 replicates per group); (F) Beta diversity was assessed by principal co-ordinates analysis (PCoA) at Bray–Curtis distances (n = 6 replicates per group); (G) Beta diversity was assessed by non-metric multidimensional scaling (NMDS) at Bray–Curtis distances (n = 6 replicates per group). CON = piglets fed the basic diet; EO + OA = piglets fed the basal diet supplemented with essential oils (EO) and organic acids (OA). ∗ means significant difference (P < 0.05).
