Abstract Dietary supplementation of herbal essential oils is recommended for aquatic animals due to their growth-promoting, immune, and antioxidative potential. Hence, the present study evaluated the inclusion of menthol essential oil (MNT) at 0.1%, 0.2%, 0.3%, and 0.4% on the growth performance, digestive enzyme activity, immunity, and antioxidative responses of Nile tilapia. After eight weeks, samples were collected, and fish was exposed to acute ammonia challenge at 5 mg TA-N/L for 6 h. The results displayed that dietary MNT significantly enhanced the final body weight (FBW), weight gain, and feed conversion ratio (FCR) in a linear and quadratic manner (P

膳食薄荷醇精油增强了尼罗罗非鱼 (Oreochromis niloticus) 的生长性能、消化酶活性、免疫相关基因和对急性氨暴露的抵抗力

摘要 由于草本精油具有促进生长、免疫和抗氧化的潜力，因此建议水生动物在膳食中补充草本精油。因此，本研究评估了包含 0.1%、0.2%、0.3% 和 0.4% 的薄荷醇精油 (MNT) 对尼罗罗非鱼的生长性能、消化酶活性、免疫力和抗氧化反应的影响。八周后，收集样品，将鱼暴露于 5 毫克 TA-N/L 的急性氨气挑战中 6 小时。结果表明，日粮MNT以线性和二次方方式显着提高了最终体重（FBW）、增重和饲料转化率（FCR）（P
