This study aimed to evaluate the impact of different levels of galangal (Alpinia  galanga) supplemented diet on productive performance, lipid profile, biomarkers of antioxidant status, carcass traits, economical efficiency, and production index of broiler chicks. A total of 180 unsexed broiler chicks (Arbor Acres) at an age of seven-day-old chicks were randomly divided into 5 treatments (36 chicks each) divided into 6 replicates (each replicate of 6 chicks). The first group fed the basal diet (control); while the 2^nd, 3^rd, 4^th, and 5^th groups were fed the basal diet supplemented with 0.25, 0.50, 0.75, and 1.00 % galangal, respectively. Data revealed that treatments groups with supplemented different levels of galangal had greater productive performance, economical efficiency, and production index compared to the control group. All treatments with different levels of galangal were decreased total lipids, triglycerides, cholesterol, low-density lipoprotein (LDL), malondialdehyde (MAD), and increased glucose, thyroid hormones (T3-T4), high-density lipoprotein (HDL), total antioxidant capacity (TAC), glutathione peroxidase (GSH-Px), and superoxide dismutase (SOD) compared to the control group (within normal range). In conclusion, it can be considered that galangal supplementation at 0.25% of diet improved the growth performance and physiological status of broiler without any adverse effects on blood parameters of broiler chicks.
