The weight gain trend of the offspring in the two groups of rats. A The image of a rat in the Control at age of 6 weeks old. B The image of a rat in the antibiotic group at age of 6 weeks old. C There was no significant difference in the weight from birth to 1 week old between the two groups, the offspring exposed to antibiotics during pregnancy (C, n = 50) had a higher body weight than the Control (C, n = 55) at 2 and 3 weeks old, but had a lower weight at age of 6 weeks old (A, n _{Control group} = 30; B, n _{antibiotic group} = 26) .*P < 0.05, **P < 0.01, ***P < 0.001
