Genealogical lines of breeding mares as biological resources of a thoroughbred horse breed bred in the Stavropol Krai

Abstract

Abstract Tribal horse breeding is one of the priority areas of livestock in the Stavropol Territory. The article provides an analysis of the population of purebred horse breeding mares bred in the leading farms of the Stavropol Territory (OOO “SKHP Svobodnyi trud”, OOO “SKHP Novomarevskoe”, FGUP “Rassvet-Stavropole”). An assessment of the mares of the pedigree core of purebred horse breed showed that their genealogical structure is represented by 12 lines. It should be noted that the 5 lines of Norsen Dancer, Native Dancer, Nazrullah, Fairway and Tern-Tu go back to the same ancestor – the Falaris line, which is 82.6 % of the total number of breeding mares. The data obtained correspond to the general trend that is observed in the global structure of purebred horse breed. An analysis of the genealogical lines of the pedigree nucleus of purebred horse mares in the Stavropol Krai revealed their optimal linear and age structure. A zootechnical assessment showed that according to measurements and indices, the mares of the farms analyzed correspond to the breed standard. The research results can be recommended as educational material for students and undergraduates of universities studying in the areas of preparation of zootechnical profile.
