Abstract
One of the most important tasks of the agro-industrial complex is to find a reserve for increasing the production of livestock products and especially beef. To increase beef production, it is necessary to rationally use the resources of cattle breeding, which consist primarily in the reproduction of the herd, increasing the live weight and fatness of young cattle sold for meat. The obtained data can be used to create highly productive factory lines and breed groups of Kalmyk cattle with increased meat productivity, high growth intensity, milk production and better reproductive abilities. This, in turn, will make it possible to supply the farms of the region with high-value breeding products for developing beef cattle breeding. The article presents the features of growth and development of young Kalmyk breed. The results indicate the dynamics of growth and development of youngsters, in addition to their exterior qualities.
