Abstract: At the current stage of development of dairy cattle breeding, it is necessary to use all means to save this important branch of livestock farming from stagnation and decline. In addition to improving the breed of dairy cattle itself, a special place is occupied by the correct standardized feeding of cows, taking into account the physiological state of the animal and the conditions of its maintenance (season, microclimate, etc.). An important factor is the preparation of heifers for mating and the creation of a dairy herd, i.e. future cows, their maintenance, i.e. the organization of their feeding. Improper feeding at this time can lead to a significant milk shortage in the future. Therefore, we conducted comparative studies of calves from birth to the age when fertilization can be carried out. The methods of raising young animals significantly influenced their growth and development until successful fertilization. It was found that calves of the experimental group exceeded their peers in live weight by 11.95%. Thus, calves raised up to six months of age using intensive technology according to the feeding scheme presented by us (using the BEST MIX premix) grew better and by mating reached a live weight of 364.0 kg by 16 months of age, compared to the control group - 339.5 kg, which was lower by 24.5 kg (6.7%). The economic effect of raising heifers using the proposed technology is -11.9%. Dairy farming is a labor-intensive, but high-tech, intensive, and with proper labor organization with automation and digitalization of production lines, a profitable, highly efficient and highly profitable industry.
