The results of studies of reproductive ability of ewes Ascanian Karakul Breed of two types (Askanian Prolific Types of Karakul sheep of black color and Breed Type of grey color), as well as to determine the influence of the individual factors (age, body weight) on the reproductive function of ewes are given in this article. It was found that both types of ewes have a high reproductive capacity and prolificacy. The ewes of black color had the indicators of reproductive capacity and prolificacy at a level of 95,6% and 156,9%, while the ewes of grey color – 94,4% and 145,7%, respectively. Ewes of twoyear age had the smallest prolificacy (1,55 heads from prolific type and 1,33 heads - from ewes of grey color breed type), and the ewes of five-year age had the highest level – 1,67 and 1,62 respectively. However, the difference, which was set, was not reliable. Also, it is determined that an increase in body weight of ewes increases their prolificacy. The ewes of a live weight from 40 to 50 kg had the lowest yield of lambs (1,46 and 1,49 heads from the ewes with black coat color and a 1,23 heads from grey), and the highest had from 61 to 70 kg (1,64-1,71 heads and 1,67-1,50 heads), respectively. In general, the Ascanian Karakul Breed of sheep of two studied types have a high reproductive capacity. Ewes of this breed can be used to increase the number of livestock, due to greater output of lambs that will enhance the economic efficiency of sheep breeding industry.
