This experiment examined the potential of olive leaf powder (OLP) as a natural growth enhancer in broiler feed and its influences on performance, carcass characteristics, blood parameters, intestinal bacterial count. A total 210 one-day-old Arbor Acres chicks were randomly allocated into three groups. The control group was given basal diet only, 2nd 3rd groups supplemented with 1 g OLP 2 OLP/kg diet, respectively. Each consisted seven replicates 10 unsexed each. experimental trial lasted for thirty-one days. Results showed that, OLP2 exhibited significant increase live body weight (LBW) at days 14 21 age, whereas OLP1 experienced considerable rise gain (BWG) between 29 31 age. Average daily intake (ADFI) considerably decreased during first 8-14 trial, but increased next 29-31 throughout entire duration (1-31 days). While, Feed conversion ratio (FCR) improved 15-31 trial. Carcass breast yields significantly supplementation, while abdominal fat content reduced. Blood analysis revealed enhances protein, albumin, globulin levels both groups, alanine transaminase (ALT), creatinine, cholesterol (TC), triglycerides (TG), very low-density lipoprotein (VLDL) Notably, immunity antioxidant markers improvement supplementation. Due to number beneficial bacteria such Lactobacillus rose all harmful (E. coli Clostridium) caecal samples declined. In conclusion, supplementation per kg demonstrated positive impact quality, lipid profile, immunity, status, raised contents chickens, making it promising promoter poultry production.
