Protozoan counts were followed in the rumen of calves in the period of milk diet. In the third week of calves' age the total counts of protozoans in 1 ml of rumen contents made 1.48 +/- 0.91 (log 10 +/- SEM). These counts were increasing gradually to reach in the seventh week of age the value of 5.54 +/- 0.19 (log 10 +/- SEM) in 1 ml of rumen contents. An increase in the protozoan counts in the seventh week of age was significant in comparison with the preceding four weeks. Total protozoan counts were converted also per 1 g of rumen content dry matter.
