RESULTS REGARDING THE BEHAVIOURAL INDICATORS DURING THE AUTOMATIC MILKING OF THE DAIRY CATTLE EXPLOITED AT S.C.D.A. SIMNIC CRAIOVa

Respiratory rate accelerates during this action both at the morning milking and at the evening milking, which proves that automatic milking is stressful both during milking and after milking. During milking, the animals’ pulse is altered and its rate increases significantly, especially during the evening milking. The milk production of Holstein Friesian cattle is about 35 litres/day, among which 53.48 % from the morning milking and 46.52 % from the evening milking. The values of the milking duration, both in the morning and in the evening, are registered in the framework of the limits of action of the hormone called oxytocin, that controls the milk secretion. The speed of milk removal may be considered as adequate for the morning milking, but it is under the limits of the minimum requirements for the evening milking
