The aims of the present study were to determine effects of dietary vitamin ADE supplemetation on reproductive performance of 8923 Ross 308 broiler breeder hens. The experimental design was a random-sample design using a 2 x 8 factorial arrangement (2 treatments with and without vitamin ADE supplementation that consisted of 4,000 IU vitamin A
800 IU vitamin 0 and 5 mg E/kg feed and 8 ages from 56 to 65 weeks old) with four replicates. Vitamin ADE supplementation increased egg production, incubated eggs and weight, reduced feed intake and feed conversion ratio (P0.01): Egg production, weight and mass were reduced as laying hens got older (P0.01). It is concluded that 'the vitamin ADE supplementation improved reproductive performance and reduced FCR of hens.
