Online published on 30 April, 2019. Abstract The purpose of this study is to determine the substitution of rice bran with phytase enzymes in commercial feed on the performance broiler. The experimental design used in this study was complete randomized design. Thirty five male broilers strain CP 707 were randomly divided into five treatments. The treatment consist of: P0 = 100% commercial feed (control), P1= 95% commercial feed + rice bran with phytase enzymes 5%, P2 = 90% commercial feed + rice bran with phytase enzymes 10%, P3 = 85kg commercial feed + rice bran with phytase enzymes 15%, P4= 80% commercial feed + rice bran with phytase enzymes 20%. Treatment was given to chickens aged 20–35 days. Carcass weight and abdominal fat was measured at 35 day of age. The results of data analyzed using Anova and Duncan Multiple showed that substitution of rice bran with phytase enzymes 15% in commercial feed affected weight gain, feed conversion, percentage of carcass and abdominal fat that give good performance broiler.
