FIELD: animal science. ^ SUBSTANCE: the present innovation deals with dynamic loading onto cardio-vascular system in animals. Selection should be carried out by the following parameters: , DeltaT3 and Deltan, where DeltaT1 - the time for pulse increase at running, DeltaT2 - the time for pulse stabilization after running, DeltaT3 - the time for pulse increase after running, Deltan - the increase of pulse frequency after running. One should select animals into milking herd at the following values; DeltaT3 <= 10 sec, Deltan <= 10 beats/min. The method enables to present perspective evaluation of lactation capacity in animals. ^ EFFECT: higher efficiency of selection. ^ 1 dwg, 1 ex, 1 tbl |
