Method of selection cows for milking on a robotic installation

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 selected 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 %.
