Abstract

The aim of study was to determine the use of varies levels of wheat bran as dietary fiber source in broiler chicks and its influence on productive performance, nutrient utilization and economic efficacy. The experiment was conduct with 120 broiler chicks; Indian River (IR) located in cages (10 chicks\cage). The chicks were randomly assigned four treatments (control and T1-3), each with 30 chicks (3 replicates/10 chicks) control 0 %, T1 5%, T2 7.5% and T3 10% wheat bran as dietary fiber (9.07%), and during the period of 35 days of age. Feed and water provided each for ad libitum consumption. All diets contained a balance concentration of 23% crude protein in starter (1-21 days) and 21% in grower diets (22-35 days) of age. The results of this study indicated that, an inclusion rate up to a level of 10% wheat bran in broiler diets was without negative effects in live body weight, body wight gain, feed consumption, feed conversion ratio, calorie conversion ratio and protein conversion ratio. Relative economic efficacy value was improved by 25% T1, 24% T2 and 20% T3 respectively, compared to control group. It can be conducted that, using wheat bran as dietary fiber up to levels of 10% in broiler diets can improved economic efficiency without negative effects on overall performance.
