For somatic cell count (SCC) the LACTOSCAN Somatic Cells Counter device was used. Some parameters were not in accordance with what is allowed by the normative instruction for cow's milk, for containing added water and for being with values lower or higher than what is recommended, however, there were parameters that generated ideal data, as regulated by IN 62 for milk quality.
