　　为进一步确定共轭亚油酸(CLA)对草鱼肝脏的降脂功效，本研究采用65d、无鱼粉和鱼油配方的生长实验、显微和超微病理观察确定CLA显著降低其肝脏脂肪含量且不影响其生长和健康的添加量(CLAOPT)，并探讨CLA在草鱼肝脏中发挥降脂功效的潜在机理.共配制7种等氮等脂饲料，其中CLA添加量分别为：0％(对照组)、0.6％、1.2％、1.8％、2.4％、3％、3.6％，分别补充椰子油至3.6％的总外源脂肪水平.

　　A 65-day feeding trial,and histopathological and cytopathological examinations were further conducted to identify the lipid-lowering effect of CLA and the optimal dose of CLA(CLAOPT),and the potential mechanism of this effect for grass carp.The CLAOPT referred to the dose that can not only significantly decrease liver lipid concentrations,but also it could not bring the negative effects on the growth performance and fish health.Seven diets containing 0(control),0.6,1.2,1.8,2.4,3 and 3.6%graded CLA levels ...
