Alpha and beta diversity analysis of the groups under study. Non-treated piglets born to ceftiofur + tulathromycin treated sows (CT_sowN_piglet, red); ceftiofur treated piglets born to ceftiofur + tulathromycin treated sows (CT_sowC_piglet, green); non-treated piglets born to ceftiofur treated sows (C_sowN_piglet, blue). A Alpha diversity boxplots estimated with Chao1 and Shannon indexes. Each dot represents a sample. Dots corresponding to outlier simples are coloured in black. B Beta diversity PCoA analysis computed with Bray–Curtis dissimilarity index, of the groups under study. Each dot represents a sample. Ellipses of confidence are calculated using Euclidean distances within the samples of each group.
