Abstract
The high genetic potential of productivity and a similar level of animal feeding underlie the intensive technology of rearing young animals for dairy cattle breeding. The realization of the genetic potential of dairy productivity of livestock largely depends on the efficiency of rearing young animals. Therefore, proper feeding of livestock is one of the main factors contributing to the maximum realization of this potential of animals. The conducted studies have shown that the breeding plants of the studied region successfully solve the issues of intensive cultivation of repair young animals. The increase in live weight of heifers allows for the first insemination at 16–17 months with the corresponding live weight. However, in the whole region, the data on the growth and development of heifers are significantly inferior to the indicators of breeding plants and the first insemination is carried out at 19 months and older. As a result of the conducted research, a plan for the growth of repair young animals was developed and the average daily live weight gains for the growing periods were recommended. The demand of reared young cattle for metabolic energy and crude protein is calculated.
