In this experiment, 30 weeks-old, eighty four Iraqi drakes and sixty ducks were randomly divided into 4 equal groups  and fed dietary L-carnitine for 12 weeks (0 mg/kg diet; control group (T1), 50 mg/kg diet (T2), 100 mg/kg diet (T3) and 150 mg/kg diet (T4). The traits examined were egg fertility, hatchability and mortality of embryos and some blood sex hormones. L-carnitine significantly increased (P≤0.01) the fertility, hatchability of fertile eggs and hatchability of total eggs and significantly decreased (P≤0.01) embryonic mortality during all three hatching cycles. However, the supplementation of dietary L-carnitine at levels of 50, 100 or 150 mg/kg to a basal diet significantly increased (P≤0.01) blood testosterone in drakes during all three months of experiment. Moreover, supplemental dietary L-carnitine at level of 50, 100 or 150 mg/kg to a basal diet significantly increased (P≤0.01) blood oestrogen and progesterone in mature ducks during all three months of experiment. We concluded positive effect of L-carnitine on the reproductive performance of drakes and ducks.
