Comparison of the microbiota composition and diversity at different stages of lactation in BM samples. (A) Boxplots of Alpha-diversity indices: Observed OTUs; Chao1; Shannon; Simpson; Ace; Pielou_e. Boxes represent the interquartile range (IQR) between the first and third quartiles (25th and 75th percentiles, respectively), and the horizontal line inside the box defines the median. Whiskers represent the lowest and highest values within 1.5 times the IQR from the first and third quartiles, respectively. Statistical significance was identified by the Kruskal wallis test with false discovery rate (FDR)-Benjamini-Hochberg (BH) corrected p values; ns = non-significant; *p < 0.05; **p < 0.01; ***P < 0.001; yellow: colostrum, red: transitional, royal blue: mature BM samples (B) PCoA plots showing the beta diversity measure using weighted unifrac distances (p = 0.012); p values determined by ADONIS; yellow: colostrum, red: transitional, royal blue: mature BM samples. (C) Relative abundances of top five most abundant bacterial phylum in the three groups. The figure was generated using (RStudio v 2022.2.3.492 with R v 4.0.5)
