Abstract

Forty eight day old F. crossed chicken (Kampung male x Lohmann layer) were divided randomly into four groups. and were fed different /ekels of rice bran (RBI in commercial ration (C11)-based experimental diet. The experimental diets were : T I (080 RB - 10080 CR 1. T2(25%4 75% CR). T3 (50% RB 50% CR). and T4 175%R B' 2.580 CR I. In each group. hody g eight gain. ratio of protein efficiency, and gastrointestinal size were measured at 10 g eeks a lier the adaptation of experimental diets. and prow in digestibility and nitrogen retention %sere measured at X ace's, after the adapt:if ion of experimental diets.
