Experiment by duration 90 days wasconducted in the summer-pasture period of maintenance on two groups of dairy cows simmental breed.Animals of control group received together with a basic of the ration standard mixed fodder K 60-32-89 to the structure of which wasincluded premix P 60-5M.On the basis of nutritive value and chemical analysis of forage in the ration of cows this group found deficit some of biologically active substances (BAS), such as Phosphorus, Sulfur, Copper, Zinc, Iodine, Cobalt, Selenium and vitamins A and D.Deficiency them in experimental group were replenished by incorporating VMA new recipe that is represented by the corrected amount (relative to a norm) inorganic salts deficit of mineral elements and fat-soluble vitamins.
It is established that use in the feeding of dairy cows VMA positively affects on the intensity metabolism of rumen. This is confirmed by a high concentration of microorganisms in the peredshlunkah (amilo-, celluloso- and proteolytic) by for parallel accumulation of crude biomass microflora, that testifies to the intensive synthesis of microbial protein. On the background of considerable advantage at the listed parameters indicators rumen environment animals of experimental group over the control significantly grows enzyme activity celluloso- and amilolytic bacteria, that predetermines intensive hydrolysis of structured and unstructured carbohydrates and formation of large amounts VFA. Along with this approved addition promoted decline level of ammonia. Increasing the intensity processes of exchange in the peredshlunkah ruminant of experimental variant predetermines respective direction metabolism and in the blood. In particular, in the organism of cows experimental group observe intensification of redox processes (growth the concentration of erythrocytes, hemoglobin) and improving the exchange of Nitrogen (reliable increasing of amino Nitrogen, total protein, decline of urea). According to the obtained data is discovered direct relationship between parameters the physiological and biochemical parameters in the organism of ruminants and their level of milk productivity. Advantage by the last criterion of experimental variant over a control analogue is 9,8 % and is a consequence balanced of the ration for above listed factors of feed by a new of VMA.
