Results of production control have shown that preservation of perennial leguminous grasses on haylage with utilization of a bacterial leaven Biomax GP reduces process of accumulation of butyric acid up to minimum (0 – 0.2% from DM forages), increases in acidity haylage up to 4.3 – 4.24 units pH and rises quantity of lactic acid up to 63.8-69.8% from total sum of acids. Feeding of haylage processed by Biomax GP to milky cows allows to increase in their milk productivity on 3.4 – 7.7%, to decrease cost price of milk (1 kg) on 2.1 – 6.0%, to increase profit on realization of milk on 17 – 44%, that enables to receive additional production counting upon 200 cows in the number of 10.0 – 35.3 million rubles per year. It is stated that bacterial preservative Biomax GP is the effective preserving means and allows to improve the course of microbiological processes in initial raw materials during its storage. It allows to receive haylage of the first class of quality. Use of such haylage in diets of milk cows increases their milk productivity and efficiency of milk production. Results of calculation have shown that use of biopreservative decreases the cost for 1 kg milk production from 0.74 – 0.84 f.u. to 0.72 – 0.82 or on 1.6 – 2.3% due to increase of cows milk yield
