FIELD: agriculture.SUBSTANCE: group of inventions relates to agriculture, in particular, to determination of individual milk yield during milking. Time of passage of each portion of milk from each teat of udder is measured for each operating cycle of the milking machine, these time intervals are integrated, and integral intervals of time are summed up from all quarters. Then total time of passage of all portions of milk is multiplied by milk yield scale and correction factor and total milk yield is calculated. Beginning and end of the passage time of each portion of yield of milk from each dolly of the cow for each operating cycle of the milking machine determines a comparator. Electrode sensor of presence of milk flow is installed in milking chamber of collector of milking device, is made in the form of four pairs of electrodes. Each pair of electrodes (2) forming one of four measuring channels is connected in parallel to one electrode to generator of alternating current pulses (1), and by other electrode is connected through comparator (3) and integral time counter (4) connected in series to adder (5). Unit of constant coefficient (6) and digital indicator of total milk yield (7) are connected in series to output of summator.EFFECT: simplification of milk yield determination process.2 cl, 2 dwg
