In the present study, examined was the effect of a yeast culture (Saccharomyces cerevisiae, Strain 47) on performance (especially on daily gains, feed conversion and condition) in an experiment with a group of Holstein calves within the period of plant nutrition. Animals received a diet consisting of 3 kg of good maize silage, 5.5 kg of grass haylage, 1 kg of meadow hay and 1.6 kg of supplementary starter feed mixture ČOT B. The yeast culture was added to the starter in the dose of 1–1. This means that each experimental calf received 1.6 g of yeast culture per day. The supplement of yeast culture showed a positive effect on daily gains and on the final body weight of calves; however, the differences were statistically not significant (P>0.05). In control and experimental groups, the mean conversion rates of concentrate were 2.19 kg and 2.13 kg, respectively. There was no difference in feed intake and feed conversion efficiency. The difference in final live body weights of calves in the control and experimental groups was also not significant. However, the condition of calves in the experimental group was much better and the scours were in general less frequent.
