¹A dominant genus was defined as its relative abundance was ≥1% of microbiota composition. ²Percentage changes (%) was calculated by first obtaining the sum of the relative abundance at day 7 minus that at day 1, then divided by the relative abundance at day 7. The difference was finally multiplied by 100%. ³ N means not detected, so not applicable.
