The experiment was carried out to compare and evaluate the effect of turmeric (TP) and cinnamon (CiP) supplementation on the growth performance of Japanese quail from G0 to G1 generation. Generation G0 had a total of 200 quails at 1 day old arranged in a completely randomized design with 4 treatments and 5 replicates, 10 birds each. Generation G1 with a total of 160 bird quails at 1 day old was arranged to be the same as the G0 generation with 4 treatments and 5 replicates, 8 birds each. The experimental treatments were: control group using only the basic diet (KPCS) without supplementation, TP: KPCS supplemented with 0.1% turmeric powder, CiP: KPCS supplemented with 0.025% cinnamon powder, and TCP: KPCS added 0.1% turmeric combined with 0.025% cinnamon powder, respectively. The experimental results showed that the treatments supplemented with TP, CP, or a combination had an improvement in the growth of Japanese quail in both the G0 and G1 generations. In the G0 generation, there was a statistically significant difference among treatments in terms of body weight (BW) and feed conversion ratio (FCR) at 28 days of age (P
