The impact of dietary inclusion of dried kitchen wastes"DKW" at 10 & 20 % with or without L-carnitine supplementation at 250 mg/ kg diet was evaluated for broiler chicken performance and economic efficiency of the diets. Results revealed that the broilers fed diets contained 10&20% DKW with L- carnitine, and 20% DKW without L- carnitine had significant (P≤0.05) heavier final BW, BWG and best FCR. Total feed intake significantly increased (P≤0.05) in group fed diet contained DKW 20% without L- carnitine. Carcass parameters were non-significantly affected (P>0.05) except GIT weight was significantly (P≤0.05) decreased through group2-5 and abdominal fat% was significantly decrease (P≤0.05) in groups fed on diets contained 10%, 20% DKW with L-carnitine. Diets contained 10%, 20% DKW with L-carnitine significantly (P≤0.05) decreased total cholesterol, triglycerides and LDL levels. Total leukocytic count, absolute heterophil count and absolute lymphocyte significantly decreased (P≤0.05) in groups fed diets contained 10%, 20% DKW with L- carnitine and 10% DKW without L- carnitine. GM of NDHI antibody titers non significantly (P>0.05) affected through group2 -5 versus control group. Groups fed diets contained 10%, 20% DKW with L- carnitine and 20% DKW without Lcarnitinesignificantly increased (P≤0.05) the total return and net profit. Economic efficiency was significantly increased while Feed cost/ kg gain significantly decreased by inclusion of diets with 10&20% DKW with L-carnitine. Conclusion, inclusion of 10 and 20% DKW with of L-carnitine supplementation in broiler chicken diet had positive effects on growth performance and economic efficiency.
