NUTRIENT DIGESTIBILITY AND PRODUCTION PERFORMANCE OF NATIVE CHICKEN FED DIET COMPOSED OF FERMENTED RICE BRAN

Abstract

When a high amount of rice bran used in the diet results a low-nutritive diet. This is a common problem in poultry ration, especially for native chicken in Indonesia, because of its low protein, high fiber and anti-nutritive contents. Fermentation using rumen content/liquid of cattle as a starter, is a simple method that can be applied to increase quality of rice bran and it is possibly easy to be adopted by the farmer. Two hundred birds of one-month old of native chicken (initial body weight was I97 i I7 g) were divided into 5 groups of treatment (4 replications and I0 birds each) based on the experimental diet that were provided in the present study. Compositions of experimental diet were as follows: (T1). Raw rice bran (40%), yellow com (40%) and concentrate (20%). (T2). Fermented rice bran (FRB, 40%), yellow com (40%) and concentrate (20%). (T3). Diet T; + 0.075 % thyroid gland powder (T GP). (T 4). FRB (60%), yellow com (20%) and concentrate (20%). (T5). Diet T4 + 0.075%TGP. The following parameters namely, digestibility of protein and crude fiber, body weight gain, carcass weight and concentration of blood cholesterol were statistically analyzed based on analysis of variance in a completely randomized design, and it was continued to Duncan for significance test. Crude
protein and fiber digestibility body weight gain, and carcass weight were significantly increased by feeding 40% of FRB supplemented with (T3) or without (T1) TGP. However, feeding 40% of FRB added with TGP (T3) and 60% of FRB with (T;) or without (T1) addition of TGP were found to decrease concentration of blood cholesterol as compared to that of T1.
