FIELD: agriculture.
SUBSTANCE: method of predicting milking capacity of Holstein first-calf heifers of different lines comprises the selection of the first-calf heifers by determining the productivity index. At that the average amount of milking of a line of the first-calf heifers for 1 lactation and their average body weight during this period is determined, and the index is used as the milking coefficient which is defined by formula:
EFFECT: increased accuracy of prediction.
