A new method of selecting cows for milking on a robotic milking installation is presented. The method includes a two-stage selection of first lactation cows. At the first stage, first-calf heifers are selected according to the optimal requirements for the udder. At the second stage, animals se-lected according to the number of voluntary milking. Animals that have this indicator less than the average for the herd by 1 sigma are rejected from the herd. Economic research has been carried out to test the method. It was found that 11 % of first-calf heifers were assigned to the cull group. They were milked 28.5 % less than animals of the main group. First-calf heifers of the main group surpass their peers in the culling group in terms of milk yield by 42.2 %.
