Abstract
Modern selection of beef cattle is impossible without a comprehensive assessment of the breeding value of an animal, which allows to analyze the transfer of a selection trait to offspring, to separate factors of production environment, to move from historically established phenotypic to genetic selection, in which selection of animals is formed only by their genotype. The article contains the results of research, the purpose of which was to study the genealogical structure and exterior-constitutional features of the Limousin breeding stock, bred in JSC “Turovschina” of Zhitkovichi district of Gomel region. It has been established that the greatest number of cows of the selection group belongs to the genealogical lines of bulls: KERN 767553941 (51 heads), NEBULEX 1096 (14 heads) and No. 4902116 (13 heads). Higher constitution indices (blockiness and breast) are typical for first-calf heifers, while boneiness and massiveness - for full-grown cows.
