Regarding TCB levels from 1st to the 4th day, no significant difference was noticed (P>0.05). Table 2 sorts the results of comparing TCB levels of the infants, according to the intervention days, in two intervention and control groups. There was a significant difference between two groups with respect to the defecation frequency on the 4th day (P=0.015), that is the frequency of defecation in the intervention group was higher. In Table 3, results of comparing defecation frequencies are sorted against intervention days in two groups
