This research was carried out in the breeding farms of the West Kazakhstan region (Aisulu farm, Hafiz farm, Dongelek farm and Plemzavod Chapaevsky LLP). The object of the study was to obtain the young cattle of Kazakh white-headed breed from cows in different calving seasons. Using modern methods of economic analysis in the agro-industrial complex and predicted economic efficiency indices, the authors determined the economic efficiency of raising young animals depending on the calving season. The study of growth and development of young stock was carried out monthly by weighing the calves in the morning before feeding and drinking. Based on the weighing results, the authors determined the following parameters of the productivity of young animals : the live weight of heifers and bulls of the Kazakh white-headed breed of different birth seasons; average daily weight gain of young animals; the features of the exterior and constitution of the young cattle were studied by taking basic measurements of the physique and calculating the physique indices based on them. The data obtained indicated that each farm was characterized by specific conditions for calving according to the seasons of the year, which must be taken into account when organizing herd reproduction and scheduling of mating, insemination and calving.
