| 摘 要： | 为评估饲料中添加水飞蓟素对吉富罗非鱼生长性能、肝脏脂肪代谢酶和抗氧化能力的影响,分别在5组等氮等能的吉富罗非鱼饲料中添加不同水平的水飞蓟素0(对照组)、100、200、400和800 mg/kg],饲喂初始体质量为(8.17±0.31)g的吉富罗非鱼幼鱼9周,测定实验鱼的生长性能、血清生化指标、肝脏脂肪代谢酶活性及抗氧化酶活性。结果显示,随饲料中水飞蓟素添加水平增加,吉富罗非鱼终末体质量、增重率、特定生长率和肥满度均呈先增加后降低的趋势,各指标均在100mg/kg实验组达到最大,100mg/kg实验组的饲料系数显著低于对照组。饲料中添加水飞蓟素显著降低了实验鱼肝体比和脏体比。100mg/kg实验组全鱼、肌肉和肝脏的粗脂肪含量显著低于对照组。血清谷草转氨酶和谷丙转氨酶活性随水飞蓟素水平增加呈先降低后升高的趋势,分别在200和100 mg/kg实验组达到最低,两组之间无显著性差异。饲料中添加水飞蓟素后,血清中的甘油三酯含量显著低于对照组;肝脏中的脂蛋白脂酶和总酯酶活性显著高于对照组;肝脏脂肪酶活性呈先上升后降低趋势,在200 mg/kg实验组最高,且与对照组有显著性差异。饲料中添加水飞蓟素后,肝脏谷胱甘肽过氧化物酶活性显著高于对照组,肝脏过氧化氢酶活性显著低于对照组;肝脏丙二醛含量显著低于对照组。100 mg/kg实验组罗非鱼的肝细胞界限清晰,无核偏移,空泡较少。研究表明,饲料中添加适量水飞蓟素提高了吉富罗非鱼生长性能,调节了肝脏脂肪代谢酶活性和抗氧化能力,对防治肝脏细胞损伤有积极作用。在本实验条件下,推荐吉富罗非鱼幼鱼饲料中水飞蓟素添加水平为100 mg/kg。
