TT, treatment; WD, withdrawal. 1Fecal samples collected within the three treatment periods (day 8, 14, 25, 28, 39, and 42) were considered as repeats for treatment. Values are means (n = 6). 2Fecal samples collected within the three withdrawal periods (day 18, 21, 32, 35, 46, and 49) were considered as repeats for withdrawal. Values are means (n = 6). 3Mean values of the community metrics calculated from the total 12 samples collected post medication in each group. Values are means (n = 12).
