FIELD: chemistry, biochemistry.

SUBSTANCE: invention relates to area of microbiology and biotechnology and can be applied in agriculture. Novel strain Megasphaera elsdenii is characterised by ability to utilise lactate with degree from 40% to 90% even in presence of sugars. Strain with said ability is obtained by method, which includes culturing of sample of paunch liquid. Novel strain Megasphaera elsdenii is applied in method of treatment and prevention of lactic acidosis of ruminants, in composition of veterinary preparation for treatment and prevention of said disease, in method of milk productivity increasing and in method of increasing ruminants fattening efficiency, in method of increasing growth rate and reduction of time of ruminants fattening, in method of reducing morbidity, induced by digestion disorders, and death rate among ruminants from lactic acidosis, as well as in method of increasing efficiency of conversion of ruminants diet based on concentrated forages when transferring ruminant to said diet.

EFFECT: obtaining ability to carry out wide-scale treatment and prevention of lactic acidosis.
