THE INFLUENCE OF BREEDING METHODS ON THE PRESERVATION AND IMPROVEMENT OF THE HORSES OF THE KUSTANAY BREED

The success of horse breeding is directly related to the organization of breeding. The article presents an analysis on improvement of breeding and sports features of horses of Kustanay breed in the process of development of breed from the moment of approbation. The aim was to determine the impact of the existing plant lines on the preservation and improvement of Artisanal horses. The estimation of stallions-producers on the quality of progeny was carried out and the applicants were determined as ancestors of new lines. To conduct research at the farm, three groups of young of different genotypes have been formed: I group of stallion-manufacturer Nauryztoy 9 (line 464 Neon), II group of stallion-manufacturer - stallion Preferans 5 (line 494 Forts) and III group - control (other lines). It has been found that the modern stock of horses of Artisanal breeds is characterized by superiority in the complex of features in the section of factory lines 464 Neon and 494 Forts over the peers of the control group - both on tribal and sports qualities. In this connection, stallions-makers: Nauryta 9 (512 Nag - 2146 Torquay 8) and Preferans 5 (525 Pegasus - 2101 Safari) on the assessment of the quality of the offspring correspond to the status of improving and can be assigned to lay two new lines in the bush horse breed. The research was carried out within the framework of the scientific and technical program BR 10764999 “Development of technologies for effective management of the breeding process and conservation of the gene pool in horse breeding” 2021-2023 of the Ministry of Agriculture of the Republic of Kazakhstan.
