A research was conducted to elucidate the effect of probiotic, prebiotic and synbiotic supplementation in drinking water on the performance of Indonesian Native Chickens (INC), the offspring of  in ovo 1.5%  L-gln hens. A randomized Block Design of 4 treatments (P0=control; P1=Prebiotic (10 g Inulin in 1 l tap water); P2= Probiotic (2 g Promix in 1 l tap water), and P3=Synbiotic (10 g Inulin + 2 g Promix in 1 l tap water) with 3 times of replication blocks was used. An amount of 180 one-day-old (DOC) of INC from 3 hatching periods was used in the research, which was selected from newly hatched chicks as the offsprings of laying hen resulted from the  in ovo  L-gln. The chicks were put in brooding boxes separately for each treatment unit (maximum 15 chicks per box) and placed in a rearing room (27-28 0 C; 60% RH). The results indicated that supplementation of pre-, pro-, and symbiotic during the first 2 weeks through drinking water did not significantly affect the body weight and feed conversion ratio (FCR) of INC; Afterward, measuring at weeks 4, 6, and 8, supplementation resulted in significantly heavier body weights and better FCR compared to those of control chicks. In conclusion, this study has shown that supplementation of pre-, pro-, and symbiotic exert positive effects on the growth and FCR of INC, and the best response is to symbiotic supplementation.
