The research was carried out at an enterprise in the Sverdlovsk region. Two groups of black-motley cows were formed: the first including cows of free stall housing with a robotic milking system; the second having tied cows that were milked into the milk pipeline. It was found that udder measurements of animals of the first group had greater values than those of the second group.

The article theoretically confirms the inevitability of cow`s idle milking caused by uneven development of udder quarters and varying duration of cow`s milking in a group. The mathematical dependence of milking machines over-exposure on the udder depending on the number of milking machines used and the time of preparatory-final operations has been determined.
