The current study was to investigate the effect of different enriched cages and lohmann strains in behavior of layers. A total of 480 layers of lohmann breed, at 30 weeks old (240 lohmann brown "LB" & 240 lohmann selected leghorn "LSL") were reared in 2 types of enriched cages "Salmet & Big dutchman". The results revealed that the most of normal behaviors were significantly higher in salmet system, while nesting and other abnormal behaviors "feather pecking" were significantly higher in big dutchman. All normal behaviors in the present study were higher in LSL with significant difference in eating, preening, nesting and resting behavior. Neverthless, abnormal behaviors were significantly higher in LB. In conclusion, good selection of cage system and strain of layers play role in improvement normal behavior and control of abnormal behavior.
