The given research results of feeding highly productive cows with new forage supplement of humic-melanoidine nature during the milking period show stable mineral metabolism, correction of their redundant supply within the diet, perfection of digestion and transition into milk as well as minimizing consequences of metabolism intensification. Reception new forage supplement promoted improvement of mastering by an animals organism of necessary iron during the given physiological period, to restriction of mastering of the microelements equal to the category of heavy metals

Results of the scientifically-economic experience lead in farm Zarechje (Smolevichskij district of the Minsk area) have shown, that perfect metabolizable energy concentration in dry matter of a diet at milking period for first-calve cows is 11,7 MJ/kg. It allows to increase natural milk productivity at 8,24% (27,4 against 25,4 kg) and 4%-milk outcome – at 8,93% as well as effective usage of metabolizable energy for production up to 4,9% (P less than 0,01) and minimum of production warmth loses
