The current study aimed to investigate the eects of a housing system, and dietary supplementation of rosemary and cinnamon essential oils on layers performance and egg quality. A factorial arrangement (2  3) was performed including two housing systems (floor and cage) and three dierent types of essential oils (0, 300 mg/kg diet of rosemary and 300 mg/kg diet of cinnamon essential oils) to study their eects on the productive performance, egg quality, immunity, oxidative stress and haematology of laying hens during the production stages. The data suggested that the supplementation of rosemary and cinnamon essential oils in laying hen diet showed significant positive eects on hen performance and egg production. Additionally, the dierent housing systems did not result in any positive or negative impact on these traits.
