The milk analysis took place in the laboratory of animal products' quality of the special department of the Agrarian State University of Moldova, by using the ultrasonic analyzer "Lactoscan", bought from Bulgary. The content's parameters of fat, protein, non-fat solids, lactose, density, freezing point, amount of water added, pH, temperature and the conductivity in the fresh cow milk had been appreciated. From the race Black & White it had been got milk content 4.1% of fat, 8.9% of non-fat solids, 4.7% of lactose, but from the Red Estonian race milk with the following indices: 4.8%, 9.2%, 4.9%.
