The article presents the results of the control slaughter of purebred and crossbred lambs. It was found that the index of compactness and the main killer performance superiority had two or three breed lambs obtained from crosses involving sheep southern meat breed. The experimental animals were taken measurements of carcasses, which give a fairly complete and objective view of the differences in the length of the torso, hips, mascara and hip girth. There are specific differences in the yield of the most valuable cuts of the first grade the rams depending on the origin. The superiority of crossbred calves over the control for this indicator amounted to 16.4 and 33.4%. The chemical composition of the meat fine-wool lambs contained more moisture and less fat and less calories than meat crossbred animals. Increasing the hybrids values of the protein quality index indicates an increase in meat share of muscle proteins and the reduction of connective tissue, and consequently, improving the quality of the raw meat. Animals obtained by crossing, have wide and deep body, well-developed muscles of the thighs, the best quality characteristics of meat productivity
