Studies have established that the highest monthly milk yield in cows of all groups was noted in the third month of lactation. In this month of lactation in cows of the III group with a live weight of 481 kg and more, the monthly milk yield was, respectively, 44 and 24 kg higher than in the peers of the I and II groups. The highest monthly milk yield of cows of groups I, II and III was, respectively, 12.33%, 12.37% and 12.53% of milk yield per lactation. Studies have confirmed that the level of payment for feed with dairy products is closely related to the level of milk production of cows. The cost of feed units for milk production in high-yielding cows is noticeably lower than in less productive peers. It was also found that the use of mobile mobile milking machines contributes to the complete milking and the manifestation of the potential of milk productivity of Holstein cows.
