Differences in growth rates are shown, as well as in the cost of rearing male and female Bufotes pewzowi under laboratory conditions. We observed a tendency for females to be superior in length and weight, but statistically significant differences (U = 13, p < 0.05) were noted only in weight after 50 weeks of rearing. Over the entire period of the study, the weight gain of females was 54.2±5.04 g, males – 45.3±6.15 g.
