AB  - The aim of this study was to examine the effect of vitamin D<SUB>3</SUB> and/or zeolite supplementation in presence of phytase enzyme on performance and enterprise income in laying hens. A total of 120, 28-weeks-old laying hens were used for the study. The laying hens were separated to 4 equal groups (5 replicates). The treatment groups were as follows: control diet (300 FTU phytase per kg), trial 1 diet (300 FTU phytase + 400 IU vitamin D<SUB>3</SUB>), trial 2 diet (300 FTU phytase + 400 IU vitamin D<SUB>3</SUB> + 2% zeolite) and trial 3 diet (300 FTU phytase + 2% zeolite). The experimental period was 16 week. Body weight and feed conversion ratio were not statistically different between groups. Egg production was significantly lower in the phytase and vitamin D<SUB>3</SUB> added group than in the phytase added group on days 29-56. Feed intake was lower in the phytase added group than in the phytase and zeolite added group on days 85-112 (p&lt;0.05). On days 1 and 112, egg weight was significantly lower in the phytase added group than in the other groups. The control group had higher income than the other groups.
