Abstract
The paper analyzes data on the fertility of sheep of the southern meat breed, studies the correlation between the fertility of the uterus and the indicators of the live weight of its lambs at weaning. The period under review covered 5 lambs. It shows a gradual increase in reproductive indicators by 3-4 lambs and their subsequent decrease associated with the extinction of fertility at an older age. The uterus, stably producing off spring capable of rapid weight gain, as well as uterus with high fertility, which can be used to preserve the valuable gene pool of the breed, have been identified.
