GROWTH AND DEVELOPMENT OF THE DUMPED BULLS OBTAINED BY THE FUTURE-BREEDING TRANSFORMATION WITHIN THE FRAMEWORK OF THE “SYBAGA” PROGRAM IN THE NORTHERN REGION OF KAZAKHSTAN

Abstract

The article presents the results of studying the growth and development of bulls of the ІI generation obtained in the framework of the program “Sybaga” by the method of conversional crossing of low-producing dairy cows and combined breeds by bulls produced by Aberdeen-Angus, Hereford, Kazakh White-headed and Aulikol breeds. Data of live weight obtained in the process of studying the
growth and development of crossbred bulls at different age periods indicate that crossbred bulls II according to the Kazakh white-headed, Hereford and Aulikol breed at the age of 6 and 8 months were lost to standard breed class 1. As an analysis shows, in the peasant economies of the North region of Kazakhstan (LTD “STAN”, “Tishkov O.V.” Farm, “Beysen” Farm and “Saltanat” Farm) plant-breeding - tribal work is conducted in the direction of creation of highly productive herd of crossbreed cattle with the use of bulls of producers of local and imported breeds. For years work great successes are attained, in peasant economies the array of the improved cattle is created from the cross-breeds of ІІ generation, a further selection is conducted on the improvement of productive
qualities of cross-breeds of ІІ generation on Aberdeen-Angus Kazakh white-haired, Hereford and Aulikol beef cattle breed, what undertaken studies testify to.
