Two experiments were conducted with the purpose of evaluating the effect of dietary supplementation of curcumin and cinnamon powders on growth performance, laying reproduction and egg quality of Japanese quails. The experiment 1: 240 fourteen days old quail chicks were assigned to four dietary treatments, each treatment consisted of six replications of 10 chicks per replicate. The experiment 2: a total of 36 laying Japanese quail hens at 36 days old which had been in production for 10 weeks was randomly divided into 4 dietary treatments with nine replicates (one female per each). The treatment diets were: (1) Control (Con) contained a basal diet without additive; (2) N0.1 contained the basal diet plus 0.1% curcumin powder; (3) Q250 contained the basal diet plus 250mg cinnamon powder/kg of feed; and (4) N0.1Q250 contained the basal diet plus 0.1% curcumin and 250mg cinnamon powder/kg of feed. Results showed that there were no effects of dietary supplementation with curcumin and cinnamon powders on FI, BW and FCR during the growing and laying periods. The supplementation of 0.1% curcumin and 250mg cinnamon powder/kg of feed resulted in significant effect on the improvement of ADG as compared to other supplemented diets. Egg laying rate, egg shell weight and yellowness (b*) score were significantly different among treatments, highest on control (89.21%, 1.26g and 48.61) and lowest on N0.1Q250 (80.93%, 1.11g and 43.56). It is possible suggested that supplementation of 1% turmeric or 0.025% cinnamon powders to improve the growth and reproductive performances of quails.
