The results are presented as the means ± SEM (n = 3). Different superscript capital letters in the same row indicate significant differences in the FFO group at different time point, and different lowercase letters indicate significant differences in the OFO group at different time point. *Indicates significant differences of two treatments at 30 days, **indicates significant differences of two treatments at 60 days (P < 0.05).
