Effects of BCB extract on pregnancy rate and number of newborn pups in normal mice. Female mice were administrated 100 mg/kg or 300 mg/kg of BCB daily for 30 days. After BCB treatment, female mice were mated with normal male mice. Pregnancy rates were measured by counting vaginal plugs (a) and numbers of pups (b). c Food efficiency ratios (FER), expressed as percentages of body weight gains on food intake. Data are presented as means ± SEMs. Groups are: Control (n = 6), BCB 100 mg/kg (BCB 100, n = 6), and BCB 300 mg/kg (BCB 300, n = 6). **p < 0.001 vs. controls
