Relationship between various phases of milk flow at mechanical milking system and the somatic cell count in cow's milk

The introduction of mechanical milking systems has made a tremendous positive impact on the working efficiency of dairy enterprises. Despite this, a certain discrepancy between the milking machines and dairy cows was soon noticed, usually not favoring the animals well being. For the udder to remain healthy, milking period should be brief, and the optimal milk flow has to be reached as soon as possible and remain constant as long as possible. Research has shown that the lowest SCC for the Holstein breed of cows (LSCC = 3.03) were observed at dIP = 0.3 – 0.6 min, and in those of the Simmental breed (LSCC = 2.96) at dIP = 0.6 – 0.9 min. Furthermore, the prolongation of the dPP of the milk flow curve has proven to have a beneficial effect on the udder health in both breeds of cows (LSCC = 2.46 and 2.50). The dPP should be prolonged by shortening the dDP, since the lowest somatic cell counts in milk (LSCC = 3.27 and 2.80) were observed when the dDP was shorter than 0.7 min.
