Twenty-four Hisex Brown hens were used in this experiment in order to describe the effect of digitonin on egg quality characteristics (weight, shell deformation, cholesterol concentration), some parameters of serum lipid metabolism (cholesterol and triglycerides concentrations) and blood picture. The experiment was split into 3 groups (8 laying hens per group); group 1 was fed control feed mixture with 16.5 % of crude protein and 11.61 MJ ME, group 2 received control feed mixture with 0.01 % of digitonin, group 3 received 0.025 % of digitonin. Digitonin in the amount of 0.025 % significantly reduced egg weight from 65.07 g in control group to 61.44 g in group 3, white weight (41.21 g vs. 37.96 g), and egg cholesterol concentration (13.64 mg/g vs. 12.95 mg/g of yolk). It increased significantly HDL cholesterol (0.43 mmol/L in control group to 0.59 mmol/L in group 3) and triglycerides from 13.47 mmol/L (control) to 16.90 mmol/L (group 3) in blood serum. Significantly lower number of erythrocytes and mean cell volume value in group 3 were observed.
