THE INFLUENCE OF THE HEAVY METALS (Zn, Cu, Cd, Pb), CONTAINED IN THE FOOD STUFF ON THE COWS' MILK QUALITY

The object of investigation: the soil, plants, the blood and milk of cows of the Golshtino-Frizski breed. The work is aimed at studying the content of Zn, Cu, Cd, Pb in the soil. foods, in the cows' organism and the determining of the influence of these elements on the milk quality. The complex study of the hard metals content in the soil - foods-cows' organism - milk with the milk productivity level to be considered, has been performed. It has been established, that the concentration of the heavy metals in milk depends on its content in the ration and does not depend on the animals' productivityAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
