After 9 weeks of experiment, a decrease of laying rate was recorded in treatment III. The mean value of laying rate for 17 weeks amounted to 82.7 (I), 82.5 (II) and 75.9% (III) (P<0.01). The egg weight was diversified already after 4 weeks of egg production and averaged 57.9 (I), 55.9 (II) and 54.9 g (III) (P<0.05). Feed intake amounted to 108 (I), 111 (II) and 104 g per hen/day (III), and FCR was 2.05, 3.17 and 2.23 kg/kg egg weight, respectively.
