The purpose of the study is to investigate the growth and formation of meat productivity of young Taurians of the Askani fine-breed breed. Research methods - zootechnical (live weight, growth rate, meat productivity), statistical (biometric data processing). Basic information on the parameters of growth, development and meat productivity of young Taurian young Ascanian fine-breed sheep was obtained. Data on the varietal and morphological composition of the carcasses of young animals were obtained Аs a result of the conducted researches it is established that the average fertilization of ewes is 83,4%. At the same time, higher rates are observed when sheep breeding by sheep of sheep lines 224 and 0058 - 85.8 and 87.1%. The average fertility of the herd is 139.7%. The intensity of development of lambs and milkiness of ewes of Taurian type were determined. It has been established that milkweed milk is 1.271 kg in bright ewes, and 1.356 kg higher with lambs According to the results of weaning lambs from ewes at 4 months of age, sheep are characterized by higher rates of live weight. Thus, their average weight is 30.3 kg, which is 9.0% higher than in the bright (27.8 kg). Indicators of growth rate of Taurian young growth by periods are established. From birth to 2 months of age, no differences were observed between rams and gulls (174 and 175 g) in terms of daily average gain. But a significant difference was found in the growth rate in favor of the bright (3.5 vs. 3.1 in sheep). The analysis of indicators from birth to 4 months of age shows a tendency of an increase in average daily increments in sheep in comparison with bright ones - 0.211 versus 0.193 kg. In terms of growth rate, the difference between the sheep and the sheep was not observed in this period and it is 6.04. Meat performance of young animals with high (more than 8.0) and low (6.5) growth rates was determined. There was a tendency for an increase in slaughter output in high growth animals (43.9% versus 43.7%). These animals also have a higher pulp yield of 11.3%. There is no difference between the study groups in terms of their composition.
