Feeding of milk cows in the silage and concentrates ratio experimental PVMА made on the basis of extruded bean fodder and non-commodity grain rape Ciscarpathia scarce in the area of macroand microelements, fat-soluble vitamins and dietary supplements of sodium humate activates rumenalnuyu fermentation, compared with analogue PVА 60-1-89. Evidence of this is the high concentration of amyloidpulp and proteolytic bacteria increased activity of amylase and tselyulaz and hence accordingly a large amount of LZHK, intense accumulation of wet and dry biomass of microorganisms, the increase in protein nitrogen and reduction - of ammonia. Against the backdrop of various levels of fermentation average daily milk yield in the control group is 19,2 kg, and the pilot – 20,9 kg.
