Abstract. In the specific conditions of the mountainous zone of the Kabardino-Balkarian Republic, the influence of the level and type of feeding of Karachay sheep on the dynamics of live weight, quantitative and qualitative indicators of carcasses and average minced meat samples, absolute and relative weight of internal organs and tissues was studied. In spring, during the lambing period, two groups of 25 experimental lambs were formed: the first group was the experimental group, and the second group was the control group. From the moment of weaning to the age of 18 months, the I group was kept according to the technology used in year-round mountain pasture coarse-wool sheep farming, with optimal feeding during the  winter  period,  which  ensured  normal  growth  and  development of the experimental animals. The II group was kept stationary during the winter period, and was fed abundantly according to the recommendations of the All-Russian Research Institute of Animal Husbandry. The conducted studies showed that in terms of live weight, the sheep of the control group outperformed the experimental ones at the age of 8 months – by 2.4 kg (P≤0.05), at 12 months – by 3.7 kg (P≤0.01), but by the age of 18 months, over the age period of 12-18 months, when keeping livestock on summer mountain pastures, the advantage of the control group decreased to 1.4 kg, the difference is statistically unreliable (P≥0.05), which confirms the relatively low adaptability of the sheep of the control group to pasture keeping. According to the actual bone  weight,  the carcasses of slaughtered lambs did not differ significantly, and small differences (0.6-1.8 absolute percent) were observed in the percentage of bone weight to carcass weight, which confirms the relatively good development of the lambs in the experimental group, which were kept on an optimal level of rations under conditions of year-round use of mountain pastures. When kept together in the same flock, under the same feeding and technological conditions, and at the same age of 8, 12, and 18 months, the lambs of the experimental group significantly exceeded those of the control group in terms of both absolute and relative weight of internal organs and tissues. The obtained data on the dynamics of live weight, the quantitative and qualitative indicators of carcasses and the average sample of minced meat, and the absolute and relative weight of internal organs and tissues are generally consistent with general biological patterns and allow us to conclude that the lambs in the experimental group, with their relatively large absolute and relative weight of internal organs, have a higher potential for metabolic processes in their bodies, which in turn affects their productivity and feed efficiency.
