machines used and the time of preparatory-conclusion operations has been determined
from the point of probability theory. Authors have confirmed the inevitability of idle
milking determinate by the varying duration of cow’s milking within a group. The
necessity to vary the duration of preparatory-conclusion operations has been shown.
To exclude the teats cups over-exposure the using of milking machines supplied with
tools for quaternary control of milking intensity has been offered. An operator getting
preliminary the actual information on dry milking of quarters has objective opportunity
to vary the duration of preparatory-conclusion operations. Exploitation during two years
of milking machines supplied with tools for quaternary control of milking intensity under
conditions of test cows has confirmed high effectiveness of its use at the dairy farm.
For the first six months of 2017 average losses of commercial milk in the test cowshed
have been 107.5 liters. In the control cowshed daily losses of commercial milk have
been about 181.9 liters. According to the data of the dairy plant the probes of milk from
the test cowshed have stable decrease of somatic cells. In compare with the control
cowshed the amount of somatic cells in milk during the analyzed period has been lower
by 4.3‒36.9%. Fat content in commercial milk from the test cowshed has been higher
by 0.01‒0.03%.
