Source of piglet fecal microbiota at three sampling times in early-life. a Proportion of microbiota from piglet feces at different days that estimated the origin from sow feces and vagina based on 16S rRNA gene sequencing data at ASVs level. b Proportion of microbiota from piglet feces at different days that estimated the origin from sow feces and vagina based on metagenomic sequencing data at species level. c Relationship between the proportion of fecal microbiota in the microbiota of piglets and Chao1 index of microbiota of piglets at species level. d Relationship between the proportion of fecal microbiota in the microbiota of piglets and Shannon index of microbiota of piglets at species level. Each point represents one sample. The X-axis represents the log10(Chao index) of the sample microbiota, Y-axis represents the proportion of sow fecal microbiota in the microbiota of piglets. The correlation coefficient (Cor) indicates the strength of the correlation. P-value less than 0.05 indicates a significant relationship. e Paired box plots showing the proportion of sow fecal and vaginal microbiota in the microbiota of each piglet. Each point represents one sample, and lines of the same color represent full siblings
