Different methods of pre-milking udder treatment of lactating cows in milking machine Elochka were studied. It is determined that the perfect method is the one that includes preliminary first portions milking, washing and wiping the udder. It differs from the ordinary one by the so called shuttle method - the partial first portion milking and wiping is carried out for the first 2 animals, after that the milking machine is set to the first and then to the second cow that allows to take into account physiological peculiarities of cows. Usage of such a perfected milking method allows increasing the interval between the start of pre-milking treatment procedures and setting the milking machine to the animal compared to the basic method at 38 sec (twice). It promotes increase of milk ejection speed during the first milking minute at 0,7 kg/min, decrease of milking time at 0,4 min, decrease of somatic cells content in milk at 65 thousand cells per 1 ml
