The aim of the research is to evaluate the efficiency of rotary type milking equipment depending on the number of animals on the rotating platform and its rotation speed. The number of milking places is a constant number for every particular milking equipment, but the speed of platform rotation can be changed adapting it to the lengths of milking cows, so that they could be milked within one revolution of the platform or within the rotation cycle. Seven rotary type parlours with 20 to 80 milking sites were included in the research. The input data necessary for the research were obtained in the process of milking in the result of timekeeping. In the research it has been found that the time of the cycle preset for rotation of the milking equipment is approximately equal with the theoretically calculated time of the cycle, and in most cases that is within the range from 7 to 19 minutes. In turn, in the conditions of exploitation the time of the operation cycle usually is in the range from 12 to 15 minutes. Whereas the productivity of work of the rotary parlour, that is calculated per one milking place, is approximately four cows per hour, and it practically does not depend on the pre-set rotation cycle time. Besides, the productivity of the rotary parlour is directly proportional to the number of milking sites in it.
