ABSTRACT. Тhe novel probiotic preparation tetralactobacterin, tested earlier on calves, was used for ensiling of grasses at the dose 50, 100, 150 and 200 g/t with bacteria titer 1×109 CFU/g. Ensiling of meadow clover in a phase of the beginning of blossoming was performed in laboratory conditions, the losses of nutrients were measured on the bases of volume and composition of generated gases. The optimal dose of preparation was equal to 100 g/t. In silo with probiotic, compared with control (spontaneous fermentation), there was indicated the increase in the concentration of protein (by 7.8%, Р<0.05), carotene (by 24%), in energy content (by 15%); percent of crude fiber decreased by 15% (Р<0.05), digestibility of nutrients elevated by 5.5 absolute percent (Р<0.05). The authors suggest that feed with probiotic bacteria will exert the prophylactic action in farm animals.
