The article presents the results of a comprehensive assessment of the possibility of producing large meat chickens of domestic and foreign crosses with the cage method of growing, considering the separation by gender. The highest broiler productivity index was 213 units, which is by 27 units higher than when growing broilers of a foreign cross. The content of histidine is significantly higher in the meat of broilers of the domestic cross (by 0.50 g in the muscles of cockerels and by 0.54 g in the muscles of hens). It was found that it is advisable to produce large meat chickens using the domestic SK-Rus 613 cross for deep processing of individual parts of carcasses. The results are confirmed by the zootechnical efficiency of broiler production, the biological usefulness of the muscle composition and meat qualities, as well as the taste and aroma properties of meat products.
