All data were expressed as the mean ± SEM of the percentage of domain bacteria at taxonomic levels (phylum and genus).

Sampling (n = 8 for HSST and n = 10 for LSST).

Abbreviations: HSST, high activity of SST with long duration of fertility; LSST, low activity of SST short duration of fertility.

¹The P values were determined using Welch's t test (*P < 0.05; **P < 0.01).
