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.
本研究旨在评估桉树叶粉（ELP）和桉叶精油（EEO）对肉鸡生长性能和免疫反应的影响。从7日龄至42日龄，总共160只肉雏鸡被随机分配到五种日粮处理组。日粮处理包括：对照日粮、添加1000或3000毫克/千克ELP的对照日粮，以及添加250或500毫克/千克EEO的对照日粮。日粮中添加ELP降低了7至28日龄期间的体重增加（BWG）。与其他处理组相比，饲喂含3000毫克/千克ELP日粮的肉鸡在7至28日龄期间采食量（FI）较低。与对照组相比，饲喂ELP或EEO的肉鸡对绵羊红细胞（SRBC）的初次抗体反应更强，但二次抗体反应的差异不显著。总之，日粮中添加EEO有增强肉鸡免疫反应的潜力。
