Research revealed that when shipping heifers of Holstein Friesian cattle from Irkutsk region to the Amur region most resistant animals were those having an average weight from 450 to 550 kilograms. Less resistant were heifers, having mass exceeding 600 kilograms. It is most often difficult to endure long transportation heifers during deep pregnancy, which leads to dehydration and severe loss of weight of 45 kilograms or more of the total weight.
