AB  - In the present study, examined was the effect of a yeast culture (Saccharomyces cerevisiae, Strain 47) on rumen fermentation of cows. Animals received a diet consisting of good maize silage with a higher dry matter content (16 kg), 16 kg of clovergrass haylage, 3 kg of meadow hay and 7.5 kg feed mixture. The yeast culture was added to the mixture in the dose 6 g/day and cow. The supplement of yeast culture showed a positive effect on VFA production in comparison with control (1.16±0.013<sup>B</sup> vs. 0.84±0.063<sup>A</sup> g/100 ml), and lower production of lactic acid. The utilisation of ammonia was higher by cows in treated group (8.68±0.084<sup>A</sup> mmol/L). The difference in number of protozoa of cows in the control and experimental groups was significant (302.0±12.349<sup>A</sup> vs. 359.2±1.304<sup>B</sup> ths /1 ml of rumen fluid).
