Abstract: The present experiment was conducted to study the effects of curry (Murraya koenigii) leaves powder supplementation on the performance of broiler chickens at Livestock Farm Complex Unit, College of Veterinary Science and Animal Husbandry, Kamdhenu University, Sardarkrushinagar, Gujarat. The study was conducted on one hundred sixty (160), straight run day old commercial broiler chicks randomly divided into four treatment groups of 40 chicks and each treatment was that further divided into four replicates of ten chicks in each. The four dietary treatments were as T₁ (control - standard diet as per BIS, 2007), T₂ (Standard diet + 1.5% curry leaves powder), T₃ (Standard diet + 2.0% curry leaves powder) and T₄ (Standard diet + 2.5% curry leaves powder). Treatment rations were started from 1^st day up to 42^nd day. Broiler pre-starter mash was provided during 1^st week of age, while, starter mash was provided during 2^nd to 3^rd week and lastly, finisher ration was given during 4^th to 6^th week of age. The observations were recorded for weekly body weights, weekly body weight gain, weekly feed intake, weekly feed conversion ratio, livability, carcass traits, cut-up parts and organ weights. The data generated were analyzed using completely randomized design. The mean body weight was significantly (P≤0.05) improved in T₂ group T₂ (2402.11±43.08 g) among all treatment groups, followed by T₁ (2304.21±37.57 g), T₃ (2274.06±53.17 g) and T₄ (2270.59±35.55 g) groups. Livability of broilers was not much affected by the addition of different level of curry leaves powder in the diet. The carcass traits were studied at the end of research period (42^th day). Addition of curry leaves powder at various level has shown significant difference among the treatment groups for carcass dressing percentage. However, 1.5 percent (T₂) curry powder supplementation group attained higher dressing percentage value (72.78±0.77) followed by control group (71.28±0.54), 2.0 percent curry powder supplemented group (70.99±0.20) and 2.5 percent curry powder supplemented group (69.41±0.77).
