Abstract. The aim of this study was to evaluate the effect of the type of milk replacer on the production results of calf rearing and hematological and biochemical parameters of their blood. Calves (heifers) of the Polish Holstein-Friesian breed, divided into two groups of 18 animals each, were maintained and fed equally, except for milk replacers used from the 31st to the 90th day of calf life. Group A received milk replacer based on skimmed milk powder, and group B received milk replacer based on whey powder. Production parameters were calculated and hematological and biochemical blood indices were determined. Better calf rearing results were found when the formula A was used. Calves, despite a lower initial weight at 30 days of age, reached a higher final weight at 90 days of rearing. There was a significantly higher number of leukocytes and erythrocytes in the blood of gorup A clves, whereas in group B there was a higher average red blood cell volume and average weight of hemoglobin in a red blood cell. In addition, there were significant differences in the levels of total cholesterol and HDL cholesterol in the blood of calves fed different milk replacers (P ≤ 0.05).
