Abstract
In the Republic of Kazakhstan, in recent years, the Kalmyk breed has been noted for its products in the meat direction in the development of meat cattle breeding. It is known that the productive properties of young animals are formed on the basis of heredity in the process of complex interaction between the organism and the environment, so the study of growth and development patterns of young animals of different genotypes is of great importance. Rations were compiled according to the fodder produced by the farm, depending on the age and sex of the animals. Feeding and housing conditions of experimental young animals before the loss of beet were organized in accordance with the technologies adopted in meat cattle breeding. The article presents research data on the dynamics of the growth and development of purebred Kalmyk in the contracts of Moskovsky LLP. During the research work on the farm, the control groups received 15 heads from birth to 12 months from each male trail: Bulls and female prints from the male Trail Moryak-120541 of group I - II; Bulls and female prints from the male trail Stroyny-2520 of Group III-IV. According to the requirements of the technology of experimental cattle breeding, control groups were fed and cared for at the same level. The control was determined according to the methodology for determining the ratio of maturity, growth dynamics of the live weight of the Young of the group, average daily growth, and absolute growth. The live weight of purebred meat Kalmyk Bulls and females at birth is 29-33 kg, and at 3 months-96-112 kg, at 6 months-149.1-167 kg, respectively, at 9 months-217.7-248 kg., and 245-310 kg at the age of 12 months.
