ABSTRACT
The aim of this study was to evaluate the effects of eucalyptus leaf powder [ELP] and eucalyptus essential oil [EEO] on growth performance and immune response of broiler chickens. A total of 160 broiler chicks were assigned randomly into five dietary treatments from 7-42 days of age. Dietary treatments included a control diet, control diets plus 1,000 or 3,000 mg/kg of ELP, and control diets plus 250 or 500 mg/kg of EEO. Dietary inclusion of ELP decreased body weight gain [BWG] during 7-28 days of age. Broilers fed diet containing 3,000 mg/kg of ELP had lower feed intake [FI] during 7-28 days compared to the other treatments. Broilers fed ELP or EEO had greater primary antibody response to sheep red blood cells [SRBC] compared to the control, but differences in secondary antibody response were not significant. In conclusion, dietary EEO has the potential to enhance immune response of broiler chickens
