This study evaluated the effect of Kaempferia galanga L. (kencur) leaf extract supplementation via drinking water on morphometric traits of broiler chickens reared under tropical conditions. A completely randomized design (CRD) was applied with four treatments: P0 (0%), P1 (1% v/v; 10 mL/L), P2 (2% v/v; 20 mL/L), and P3 (3% v/v; 30 mL/L). Broilers were reared in a closed-house system until 35 days of age, and morphometric measurements included body weight, comb height, shank length, tibia length, femur length, and pelvic-related distances. Results indicated that supplementation significantly improved growth-related morphometrics, with the most consistent improvements observed at P2 (2%). The response tended to plateau or slightly decrease at P3 (3%), suggesting an optimum dose range. These findings support the potential use of kencur leaf extract as a phytogenic supplement administered through drinking water to enhance broiler growth and
