Abstract: A study was conducted to investigate the effects of Guar Korma Meal (GKM) as a partial replacement for soybean meal (SBM) in broilers diets on growth performance, carcass traits, blood metabolites and economic efficiency. Three hundred; one-day-old Cobb-400 broilers, each with five replicates (n = 15 chicks per replicate), were submitted to one of the four diets contain 0, 25, 50, 75% SBM were replaced with GKM in starter and grower diets, respectively for 42 days in a completely randomized design. Body Weight (BW), Body Weight Gain (BWG) and Feed Intake (FI) were lower (p<0.05) in broilers fed (GKM-50) and (GKM-75) than those fed (GKM-25) and (GKM0), whereas Feed Conversion Ratio (FCR) was better (p<0.05) when broilers fed on (GKM-25). Performance Index (PI) and Performance Index Score (PIS) were superior in the (GKM-25) followed by SBM fed groups when compared to the other groups. Digestibility coefficients of OM, CP, CF and NFE were higher (p<0.05) for broilers fed on (GKM-25) than those fed other diets, however, EE was highest for broilers fed on (GKM-50) and (GKM-75). Carcass traits, cut up parts and yields significantly increased (p<0.05) for chicks fed (GKM0) and (GKM-25), while group fed on (GKM0) recorded the lowest abdominal fat (%) followed by (GKM-25) group. Ascending levels of GKM treatments influenced the carcass meat, which was observed as decrease in CP contents (p<0.05) but increase in moisture, EE and ash contents (p<0.05) in breast and thigh meat compared to (GKM0) group. Broilers fed on (GKM-75) had the highest urea, triglycerides, cholesterol, HDL, LDL and vLDL concentrations than the other treatments. The best value of Economic Efficiency (EE) was recorded by group fed on (GKM-25). High levels of GKM in broilers diets deleteriously affect growth performance, FI, FCR and blood lipids. It was concluded that optimal level of GKM is low level 25% without adverse effects on growth performance, carcass traits, blood lipids or economic efficiency of broilers.
