As a result of the researches perfect technological data of high-productive cows start and management in dry and calving sections were developed. It is determined that usage of one-moment start is economically justified. Firstly, a cow is milked adequately, obtaining usual amount of milk in a husbandry, and milk quality stays on the level, as well as within the classical method. Secondly, medicament usage for start allows increasing milk yields at least at 10% in the next lactation. Thirdly, within one-moment start the so-called medicamental udder preservation takes place, which allows protecting a cow from mastitis in dry period when the risk is higher. Dry high-productive cows management division into two periods and management in small groups in calving section promotes more comfortable and management conditions, promotes earlier expulsion of afterbirth (on 57,8 min.) and allows to safe on milk-marketable farm with 480 animals 9 livestock places in calving section of 120 m2 area
