Abstract
<jats:p>The aim of the work was to assess the effect of the genotype and age of young sheep on the ratio of the natural-anatomical parts of the carcass. An increase in the absolute weight of all cuts was found in purebred and mixed-breed young animals. At the same time, the specific gravity in the carcass of the scapular and posterior natural anatomical parts decreased with age, while the dorsal weight increased. Thus, the absolute weight of the scapular and posterior cut in purebred sheep of the Tsigai breed (I gr.) from birth to 12 months increased by 3.53 kg (13.17 times) and 6.75 kg (12.27 times), respectively, and the relative decreased by 1.88% and 3.25%. At the same time, the absolute weight of the dorsal rib cut increased by 11.59 kg (16.25 times) during the growing period, and the relative weight increased by 5.13%. A similar age dynamics of the mass of natural anatomical parts was observed in cross-bred sheep ½ edilbai x ½ Tsigai (grade II), purebred boulders of the Tsigai breed (grade III) and cross-bred boulders ½ edilbai x ½ Tsigai (grade IV). At the same time, both in terms of the absolute mass of all cuts at all age periods, and and the relative advantage was on the side of the crossbreeds, and the boulders were inferior to the sheep of the corresponding genotype.</jats:p>
