Effect of the Replacement of Soybean Meal by Rubber Seed Meal on Growth, Economics and Carcass Characteristics of Broiler

The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (40% rubber seed meal) and each dietary treatment group consists of 30 chicks under two replicated pens (R1 and R2). Chickens had freely access to feed and water thought the experiment. Body weight was taken at weekly basis. Feed was measured from each replication at weekly interval for the determination of feed intake of birds. At the end of the experiment the carcasses quality was studied. At the age of 5th week, the average body weight and body weight gain of the broilers were not significantly (P
