Abstract
Dairy cattle breeding, which is one of the most important sectors of the country's agro-industrial production and is of strategic importance, is of significant importance in ensuring food security in Kyrgyzstan. The realization of genetic potential largely depends on the productive qualities of animals. According to numerous scientific studies, it is known that selection efficiency of up to 70% is determined by the use of stud bulls, tested for the quality of their offspring. In this study, a comparative description of the descendants of different lines of Holstein-Friesian bulls used in the Chabrets agricultural company was carried out. The best sire bulls were identified based on the productivity of their daughters
