R.T. = retention time; VIP = variable importance projection.

¹Samples of fermented liquid diet collected at day 7.

²Samples of fermented liquid diet collected at day 21.

³P < 0.05 means the difference in concentration of metabolites between T7 and T21 was significant, P < 0.01 means the difference in concentration of metabolites between T7 and T21 was extremely significant.
