The article elicits results, which showed dependence of reproductive ability of Ukrainian meat breed sows with two farrows from body weight and age during insemination. The highest productivity level of sows was shown during inseminating them by animals with 199.31-219.25 kg body weight and in age of 467.1-521.5 days. There were demonstrated the indexes of interrelation of sows body weight and age with pregnancy duration and sex ratio in their farrow: at the second productive farrow the sows age increased and their body weight,; while reaching 199.3-219.2 kg of body weight, pregnancy duration decreased and stabilized in 15.6-17.4 months age.
