Abstract: The article presents the results of assessing the quality of meat carcasses of purebred and crossbred sheep. The object of the study was the carcasses of purebred sheep of the Romanov breed (group I), its crossbreeds of the first generation with the Edilbay (½ Edilbay × ½ Romanov II group) and the second generation (¾ Edilbay × ¼ Romanov – III group). The advantage of crossbred young animals of groups II and III over purebred peers of group I in terms of absolute and relative most valuable in food in relation to the posterior third of the trunk was established. This superiority in the value of the first indicator was 2.00 kg (34.30 %, P < 0.01) and 2.67 kg (45.80 %, P < 0.001), respectively, the second – 0.52 % and 0.78 %. The leading position in terms of the analyzed indicator was occupied by crossbreeds of the second generation of group III. When analyzing the indicators of varietal carcass cutting according to the trade classification, it was found that crossbred youngsters of groups II and III, due to the manifestation of the crossing effect, surpassed purebred peers of group I in absolute weight of meat of grade I by 5.58 kg (34.36 %, P < 0.01) and 7.25 kg (44.64 %, P < 0.001), relative – by 1.30 % and 1.49 %. At the same time, the crossbreeds of the second generation of group III outperformed the crossbreeds of the first generation of group II in terms of the analyzed indicators by 1.67 kg (7.65 %, P < 0.05) and 0.19 %, respectively. As for the meat of the second grade, in terms of its absolute mass, the advantage was on the side of the mixed young animals of groups II and III, and the relative – the leading position was occupied by purebred sheep of group I.
