The purpose of the work is to study the influence of the level of wool productivity of sheep of the Ascanian fine-breed Taurian breed in the conditions of the breeding plant of the State Farm of Ascanian on their reproductive qualities. Research methods - zootechnical, laboratory-analytical, organoleptic, accounting and calculation. Basic information on the level of reproductive quality of ewes with different levels of wool productivity was obtained. The performance of the wool productivity and the main breeding characteristics of the ears were obtained. It was found that animals with unwashed hair of 4.0-4.9 kg made up 3.0% of the total livestock population. The highest number of animals (37.9%) had a wool productivity level of 6.0-6.9 kg. The highest rates of fertilization were obtained by ewes with a productivity level of 5.0-5.9 and 6.0-6.9 kg - 84.9 and 84.4% respectively. The average for the flock was 82.0%. There are no established patterns of fertility. High rates were recorded in ewes with a haircut of 9.0-9.9 kg and 4.0-4.9 kg respectively of 142.8 and 137.5%. In other groups, the fertility rate was 121.9-130.0%. The average live weight of the bright was 4.7 kg with fluctuations from 3.8 to 6.2 kg, and in sheep on average 5.0 kg (lim 4.0-6.8 kg). However, no effect of the ewes' wool productivity level on this indicator was found. A moderately correlated correlation between live weight and sheep wool shear in lines 5 and 0517 was found to be 0.41 and 0.58. In other lines it was positive but low and varied from 0.16 (animals in line 8.31) to -0.19 (animals in line 1444). The results obtained indicate an unstable manifestation of the dependence of wool shear on the live weight of ewes. Analysis of the correlation relationship between the mass of ewes and the mass of their offspring indicates that their correlation is negligible for the vast majority of lines n 2019, 954 animals of different sex and age groups were evaluated for the breeding complex. The average live weight of adult rams was 103.3 kg, river rams 67.8 kg, bright river rams 47.1 kg, perekryak 68.9 kg. According to the best combination of qualitative characteristics of live weight and wool cover, 47 breeders and 38 repair sheep with average live weight of 112.1 and 74.3 kg and a lash of unwashed wool 10.2 and 7.54 kg were selected before the reproduction and repair groups.
