A corn-soybean meal based diet containing different levels of Trp (0, 0.10 and 0.20) for the starter, (0, 0.07 and 0.15) for the grower and (0, 0.05 and 0.13) for the finisher was used. In a completely randomized design with three treatments of five replicates each and 10 chickens per replicate, 150 Cobb500 male broiler chickens from 0-49 days of age were subjected to Trp diet. Growth performance (body weight gain, feed intake and feed, gain ratio) and blood serum (albumin, total protein, glucose, cholesterol, triglyceride, urea, uric acid, aspartate amino-transferase, alanine amino-transferase, alkalin phosphatase, lactic dehydrogenase and creatine kinase) parameters were measured at 27 and 49 days of age. As the result showed the increase of dietary Trp elevated (p<0.05) body weight gain, feed intake, albumin, total protein, glucose, urea and uric acid and decreased (p>0.05) feed gain ratio, aspartate amino-transferase, lactic dehydrogenase, triglyceride and cholesterol. Therefore, we conclude that dietary Trp might have positive effects on health status of the broiler chickens. ER -
