Abstract: A completely randomized design was carried out to evaluate the effects of five different fat sources (cattle bone marrow, camel bone marrow, cattle fat, camel fat and fish oil at the rate of 3%) on performance, carcass yield and blood metabolites content in broiler chickens. Two hundred and forty one-day-old of unsexed (Ross 308) were randomly divided into 6 different treatments of 40 birds and each group was divided in to 4 replicates of 10 birds: (T1) basal diet containing no supplemented fat (control group), (T2) basal diet containing 3%beef fat supplementation, (T3) basal diet containing 3% camel fat supplementation, (T4) basal diet containing 3% beef bone marrow supplementation, (T5) basal diet containing 3% camel bone marrow supplementation, and (T6) basal diet containing 3% fish oil supplementation. The treatment diets were applied to the chicken from day 2 till 49 days. The following parameters were measured : live body weight (LBW) ,body weight gain(BWG) ,feed intake(FI) , feed conversion ratio (FCR) , water consumption (WC) ,relative water consumption, (RWC) ,protein efficiency ratio (PER), energy efficiency utilization(EEU) , lysine efficiency ratio(LER) ,production efficiency factor (PEF),and carcass characteristics .Moreover, blood samples were analyzed for cholesterol HDL , LDL , urea , uric acid , total protein , albumin , triglycerides and glucose. Results showed significant difference at (p<0.01) in both weeks five and week 6 for FI, BW, WC, and PN. Week five showed significant difference (p<0.01) for EER, LER, however PEF didn’t show significance difference in week 6. Weight gain and carcass dressing % showed significant difference (p<0.01) in week 5 and (p<0.05) in week 6. Both week 5 and 6 did not show significant difference (p<0.05) for both FCR and RWC. Blood analysis did not show significant difference in all parameters analyses except for urea. These data indicated that fat supplementation could improve production performance of broiler chickens in the finishing period.

I. INTRODUCTION
The growing poultry industry in the Sudan is developing on the utilization of local ingredients to minimize feed cost, which limits poultry production in developing countries as financial constraint. In addition the competition between man and animal for protein and energy sources in developing countries made the utilization of non-conventional feed sources to increase the nutrient utilization efficiency of cheap feed ingredients [1].
