THE EFFECT OF SYNBIOTIC ON CARCASS PERCENTAGE AND ABDOMINAL FAT PERCENTAGE OF NATIVE CHICKEN

The aim of this study was to evaluate the effect of synbiotic on carcass percentage and abdominal fat percentage of native chicken. This research used 120 birds of native chicken. Basal diet in this research formulated with metabolizable energy (ME) 3000 kcal/kg and crude protein 19%. Completely randomized design used in this research with 6 treatment and 4 replicates. The 6 treatments were P0: control (without synbiotic), P1: basal diet + 1.0% of synbiotic, P2: basal diet + 1.5% of synbiotic, P3: basal diet + 2.0% of synbiotic, P4:basal diet + 2.5% of synbioticand P5: basal diet + 3.0% of synbiotic. The parameters in this research were live weight, carcass percentage and abdominal fat percentage. Based on this research showed that the treatment of synbiotic significant different (p<0.05) on live weight, carcass percentage and abdominal fat percentage of native chicken. Conclusion of the research was the supplementation of synbiotic increased of liveweight and carcass percentageand reduced of abdominal fat percentage of native chicken.
