Abstract Phytogenics additives have gained considerable attention as efficacious and safe dietary interventions to reduce the toxic effects of aflatoxin B1 contamination in aquatic animals. The present study was conducted to investigate the ameliorative efficacy of Thymus vulgaris essential oil on aflatoxin B1 (AFB1) toxicity in rainbow trout (Oncorhynchus mykiss) in terms of growth performance, innate plasma immune indices and expression of immune related genes. Five experimental diets including a commercial diet as control, control diet +25 ppb AFB1, control diet +50 ppb AFB1, control diet +25 ppb AFB1 + 1% garden thymus essential oil (TEO), and control diet +50 ppb AFB1+ 1% TEO were tested. Triplicate groups of fish averaging 20.77 ± 0.08 g were fed the test diets at a rate of 3% body weight twice daily for 30 days. At the end of the experiment, fish fed TEO supplemented diets showed improved final weight, weight gain, feed conversion ratio and specific growth rates in comparison to groups received AFB1 with no dietary TEO supplementation (P

膳食补充百里香精油改善黄曲霉毒素 B1 对虹鳟鱼 (Oncorhynchus mykiss) 生长性能和肠道炎症状态的不利影响

摘要 植物源添加剂作为一种有效且安全的膳食干预措施，可减少黄曲霉毒素 B1 污染对水生动物的毒性作用，因此受到了广泛关注。本研究旨在研究百里香精油对虹鳟鱼 (Oncorhynchus mykiss) 黄曲霉毒素 B1 (AFB1) 毒性的改善效果，包括生长性能、先天血浆免疫指标和免疫相关基因的表达。五种实验饮食，包括作为对照的商业饮食、对照饮食 +25 ppb AFB1、对照饮食 +50 ppb AFB1、对照饮食 +25 ppb AFB1 + 1% 花园胸腺精油 (TEO) 和对照饮食 +50 ppb AFB1+ 1% TEO 进行了测试。将平均 20.77 ± 0.08 g 的三份鱼以 3% 体重的比率每天两次喂食测试饮食，持续 30 天。在实验结束时，
