The effect of a yeast culture (Saccaromyces cerevisiae 1026) added to the diet with or without supplementation with a vitamin premix and mineral bioplexes on milk yield of 30 early-lactation Polish Black and White (Lowland) cows was determined in a 17-week experiment (January-April 1996).The daily ration (DM) consisted of 55% forages and 45% concentrates.Milk yield and milk composition were only slightly affected by the yeast culture given without premix, but combined supplementation with yeast culture and premix had a significant effect on milk yield and composition.Cows fed with the yeast culture produced 38 kg more milk than the controls by day 120 of lactation, whereas from cows fed yeast culture alone, the total milk protein yield, casein and lactose increased by 4.4 kg, 3.0 kg and 6.0 kg, respectively.
