Abstract

Within the framework of the study, the effect of crossbreeding Romanov and Edilbaev sheep breeds on the quality characteristics and energy value of meat was investigated. The research subjects were purebred wethers of the Romanov breed (group I), their first- and second-generation crossbreeds with the Edilbaev breed (½ Romanov × ½ Edilbaev - group II; ¼ Romanov × ¾ Edilbaev - group III). Analysis of the obtained data revealed a significant crossbreeding effect on the studied parameters. In particular, crossbred individuals from groups II and III substantially outperformed purebred animals from group I in terms of dry matter content in muscle tissue - by 41.56 and 54.48%, respectively; protein yield - by 39.42 and 50.45%; extractable fat level - by 52.80 and 76.06%. Furthermore, purebred wethers from group I showed lower values compared to the first- and second-generation crossbreds (groups II and III) in energy concentration per 1 kg of muscle tissue (by 172 and 328kJ); energy yield in carcass tissue (by 23.93 and 32.03 MJ); maturity level (by 0.55 and 1.02%). At the same time, the protein-to-fat ratio remained nearly identical across all groups. The second-generation crossbreds (Group III) demonstrated the highest values across the entire set of analysed parameters.
