¹ The top six bacterial phyla found in fecal samples of the control group are shown. Data are expressed as the mean±SEM.

² Control (n=10), Treatment (n=10).

^{a, b} Bacterial abundance in the control and treatment groups belonging to the same sample collection site with different letters significantly differ (the Mann-Whitney U test, P<0.05).
