This study was conducted to evaluate four dietary L-carnitine inclusion levels on the performance and carcass characteristics of broiler chickens. Three hundred and twenty (day old) broiler chickens were received from a commercial hatchery and reared under optimum growth conditions until 42 days of age. Upon arrival, the chicks were randomly distributed into 16 floor pens in a complete random design (4 pens/trt, 20 birds/pen). L-carnitine levels were control, 200, 400 and 600 ppm. L-carnitine had no significant effect (P<0.05) either on feed intake or feed efficiency ratio, but had negligible influence on body weight gain and survivability, though this was not significant either. Various levels of L-carnitine exhibited no significant effect on carcass characterestic, abdominal fat and carcass parts (breast and leg). Morever, carcass chemical composition (protein, fat and carcass dry content) was not affected by L-carnitine levels.
