The impacts of supplemental L-carnitine in broiler breeder hen diets were evaluated. 400 hens were obtained from (Ross-308) broiler breeder strain at 32 weeks of age. All hens were collected from the same breeder flock and weighed on a balance with 10 g precision. At 32 weeks of age, hens based on a completely randomized design were divided into 5 treatments with 4 replicates per treatment and 20 hens and 2 roosters per replicate. 400 broiler breeder hen were fed the same basal diet that was supplementation with 0 (control), 200, 300, 400, and 500 mg Lcarnitine/ kg of diet. Egg samples were analyzed for egg weight, egg production and hatching traits in newly-hatched chickens. The results of the study indicate that, dietary L-carnitine supplementation didn’t show any significant effect on egg production, weight of eggs and hatchability of broiler breeder hens from 32 to 36 weeks of age. Weight of newly-hatched chickens was significantly higher when supplemental L-carnitine in broiler breeder hen diets from 32 to 36 weeks of age were received 400 and 500 mg than control group. These data clearly indicate a potential important impact on weight of newly-hatched chickens by increasing dietary L-carnitine nutrition of a broiler breeder hen.
