The results of production experience on hydrobarathernal treatment fall rye grain feeding are presented in the article. It is determined that after high temperature and pressure impact on fall rye grain in aqueous media dextrinization of starch specifically amylopectin occurs to monosugar in the form of glucose, therewith, sugar content increases more than in twice in comparison with parent grain. It is revealed that replacement of milled corn grain mixture to fall rye grain hydrolyzate in rations brought sugar-protein proportion to norm which contributed to increasing of cows milk production, besides, of high quality. Using of fall rye grain hydrolyzate in cow rations for 12 months on the whole gave growth of milk yield in 484 kg per a cow with protein weight fraction content of 3,0%, that is higher on 522 kg for the same interval of time in comparison with the leading farm. Replacement of milled corn grain mixture on fall rye grain hydrolyzate in cow rations did not negatively reflect on biochemical blood composition of animals. All indexes fell within the limits of standard values. Using of fall rye grain in cow rations on account of its lower selling price, despite on extra charges during hydrobarathernal treatment, led to spending reduction of fodders on 1 centner of milk on 28,03 roubles in comparison with milled corn grain mixture. Extra income at Chalino farm in comparison with Stepanovo farm for one year composed 353188 roubles that led to milk primecost reduction on 8,44% at the given farm.
