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
