Abstract: At present, there is an acute need in the Republic of Kazakhstan for modernization of the beef cattle breeding industry. The solution of this problem assumes, along with the importation of highly productive foreign selection breeds, the intensification of selection of local breeds such as Auliekolskaya, that are well adapted to climate conditions, the forage base and has a stable immunity to diseases prevalent in the territory of the Republic of Kazakhstan through the introduction of modern highly effective scientifically sound technologies. One of these DNA technologies is the Marker-Assisted Selection (MAS) which allows accelerating the rates of breeding and reducing financial costs in the implementation of classical breeding activities. MAS selection uses information on the phenotypic manifestation of gene alleles responsible for quantitative traits (candidate genes) in order to assess the genetic potential of animal productivity in the early stages of postnatal development.
