Results of research have shown, that forages of natural and cultural pastures are poor on the majority of the bio - elements normalised for cattle which content in plants has considerable fluctuation depending on district, kind, than time of cleaning, etc., diets therefore are more natural cannot provide to the full requirement animal in the given elements. Cobalt and ferrum containing in vegetative forages in quantities make, sufficient cows for an organism, are the exception. Nevertheless, in blood of animals it is diagnosed often hyposiderosis, that can testify that ferrum contains in vegetative forages in the difficult assimilable form. It is not excluded also, that its mastering is influenced negatively by imbalance of diets on other elements. From all chemical elements the most significant influence on display of patrimonial and postnatal pathology of cows renders deficiency of copper and zinc. From the above-stated follows, that at the organisation of the high - grade and balanced feeding of cows it is necessary to pay attention not only to security their power and nutritious components of a diet, but also on adequate receipt in an organism macro-and microelements. This circumstance also is necessary for considering at the analysis of causes of infringement of reproductive animal function. Appointing to animal of bio - elements in the form of additives and preparations, it is possible not only to prevent the diseases caused by their deficiency, but also to normalize the exchange processes, homeostasis, to raise nonspecific resistance, to improve growth indicators, development of young growth and reproductive ability of females. For completion of mineral substances deficiency especially at highly productive animals a special top dressing in the form of complex additives or appointment of injection of veterinary mineral - containing preparations are necessary
