The invention relates to a system which, when added to mechanized milking equipment, automates said equipment and solves the problem of subclinical mastitis by "distinguishing" between the moments at which the milk stops for each individual udder quarter and removing the teat cups in an asynchronous manner and independently of each other. The system: minimizes the negative consequences of over-milking that occur when the teat cup is not removed in time after the flow has stopped reduces economic, financial, and productivity problems generated by subclinical mastitis which is primarily caused by over-milking and improves the quality and quantity of the product. Mastitis produces somatic cells in milk, the higher the proportion of somatic cells, the lower the price that the producer will receive. Damage caused to the mammary gland may be permanent and may result in the loss of the gland and may spread. The system includes teat cups, tubes, a collector, a discrete flow sensor, a vacuum sensor, a command control, and software, part of which includes the udder quarters with the physiological and anatomical characteristics thereof.Sistema que adicionado a los equipos mecanizados de ordeño los automatiza, resuelve la mastitis subclínica al "discriminar" por cada cuarto mamario individual en su retiro de pezoneras cuando se les termina la leche, asincrónica e independientemente uno del otro. Minimiza consecuencias negativas del sobre ordeño producido por no retirar a tiempo la pezonera terminado el flujo, disminuye problemas económicos, financieros, de productividad generados por la mastitis subclínica causada principalmente por este sobre ordeño mejorando calidad y cantidad del producto. La mastitis produce células somáticas en la leche, mientras mayor sea su cantidad menor es el precio que recibe el productor. El daño a la glándula mamaria puede ser definitivo causando la perdida de ésta y la posibilidad de contagio. El Sistema incluye pezoneras, mangueras, colector, sens
