Objective of this research was to determine the slaughter properties and carcass composition of carcass sides derived from young cattle of Domestic Spotted breed, of pre-slaughter weights of 500 (group A) and 600 kg (group B). Heavier cattle had higher share of kidney fat in carcass, whereas the share of offals showed no significant differences. Statistically significant difference was registered only in share of toungue (P is less than 0.05), that was higher in cattle of group A. Share of extra/premium (tenderloin), I category (round) and II category (loin, back, shoulder) showed no significant differences between groups of cattle. Statistically significant difference (P is less than 0.05) was established in the share of the 3rd category carcass parts. Share of forearm and chest was significantly higher in lighter cattle (3.55% and 7.95%) compared to heavier animals (2.89% and 6.33%), whereas the share of subshoulder was considerably lower in group A (6.89%) compared to cattle of group B (9.73%). Data obtained by dissection of main carcass side parts differed significantly in regard to the share of muscle tissue in round and belly, that was significantly higher in cattle of group A (P is less than 0.05). Share of fat tissue (subcutaneous and intermuscular) was higher in cattle of group B in almost all carcass side parts, however, statistically significant difference between groups was determined only in round, back, neck and subshoulder. Also, share of bones in chest differed statistically significantly (P is less than 0.05) and it was higher in group A (20.09%) compared to cattle of group B (15.52%).
