abstract: Oregano essential oil (OEO) has emerged as a safe, effective, and bioactive additive, increasingly incorporated into feed formulations to enhance the growth performance and overall well-being of broiler chickens. This experiment aimed to investigate the consequences of the dietary supplementation of OEO regarding the growth efficiency, carcass characteristics, and blood biochemical profiles of broiler chickens. The 35-day feeding trial involved 200 unsexed Hubbard Classic broiler chickens with an average initial body weight of 42.79 g. The broiler chicks were randomly assigned to four experimental groups, each comprising five replicates of ten birds. The treatment groups were fed basal diets supplemented with 300 mg/kg (OEO-1), 400 mg/kg (OEO-2), and 500 mg/kg (OEO-3) of OEO, while the untreated group (OEO-0) was fed a basal diet without any additives. Weekly assessments of growth performance metrics were conducted for 5 weeks, and blood parameters were examined once on day 35. The results revealed that OEO-3 treatment had a significant impact on the body weight, feed intake, and feed conversion ratio of broilers. A considerably increased dressing percentage was observed in the OEO-3 group. The findings indicated that OEO-supplemented groups significantly influenced both high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels, especially OEO-3, which showed higher HDL and lower LDL levels compared to other treatment and control groups. However, no significant effect was observed on total blood cholesterol and triglyceride concentrations in the experimental broilers. Incorporating OEO into the diet suggested that the higher doses (500 mg/kg) enhanced growth efficiency, increased HDL cholesterol, and decreased LDL and triglycerides in the blood of broiler chickens.
