Short summary

This study evaluated essential oil (EO) blend supplementation (0–2 mL/kg feed) in broilers. The 2 mL/kg group showed higher feed intake, weight gain, improved feed conversion ratio (FCR), enhanced nutrient digestibility, and elevated antibody titers against viral diseases, indicating that this EO level effectively supports growth, nutrient utilization, and immunity.
