98-Enhance of Protein Efficiency Affected by Synbiotic Supplementation in the Diet of Broiler Chicken

Abstract

The objective of this study was to evaluate the effect of synbiotic on enhance of protein efficiency of broiler chicken. The research was used 144 birds of unsexed broiler chicken at one day of age with initial body weight 45.68 g 1.52 g. Experimental design used was completely Randomized Designed with 4 treatments and 6 replicates, and every unit experiment consist of 6 birds. The treatments were as follows: T0: basal diet (without synbiotic), T1: basal diet + synbiotic 1 ml/100 g of feed, T2: basal diet + synbiotic 2 ml/100 g of feed and T3: basal diet + synbiotic 3 ml/100 g of feed. The basal diet was formulated to contain 3000 kcal/kg metabolizable energy (ME) and 22% crude protein (CP). Variables observed were nitrogen intake, nitrogen retention and net protein utility. The result showed that synbiotic supplementation significantly (p<0.05) increased nitrogen intake, nitrogen retention and net protein utility. Conclusion of the research is synbiotic supplementation at 2 ml/100 g of feed was enhance of protein efficiency of broiler chicken.
