The effect of dietary supplementation with dry bakery yeast culture Saccharomyces cerevisiae in high concentrate diet (F:C=47:53) on milk yeald and rumen fermentation were studied on two groups primiparous lactaiting cows (8 cows per group) and four ruminally cannulated nonlactaiting cows on diet
F:C=25:75. Cows fed yeast during 67 days produced 1.24 kg/d and 1.66 kg/d natural and 4% fat corrected milk respectively more, than control cows. Milk protein and fat percentages were also higher. On diet with yeast ruminal concentration of lactate was lower and butirate+propionate was higher. The yeast
incrised rumen pH, decreased NH3 in rumen and urea in blood, decreased viscosity of rumen fluid
