摘　　要：运用梯度法设计胆固醇饲料试验,用二因素三水平设计胆固醇、磷脂饲料试验。结果指出,饲料内添加胆固醇对于中国对虾有显著的促生长和提高存活率的效果,胆固醇是对虾饲料内必须添加的营养物质,根据试验虾的生长、存活以及肌肉内胆固醇的含量,饲料中添加0.5％的胆固醇就能够满足对虾的营养需求。磷脂也是中国对虾必需的营养物质,饲料内磷脂的添加能够提高对虾的存活率,增加肌肉中胆固醇的含量,就本试验条件下,饲料内含豆油3％、鱼油2.5％、胆固醇0.5％时,3％的磷脂就能满足对虾的营养需求。The dietary test of prawn was designed by means of the gradientmethod for cholesterone and phospholipid. The results showed that there were nota-ble effect both of them on promoting the growth and survival rate of the prawn. Thecholesterone is the essential adding nutrient in the formulated prawn diet. Accor-ding to the need for growth and survival and the amount of cholesterone in muscle oftesting prawn, 0.5% of cholesterone content in the diet will be enough for the nu-tritional requirement. Phospholipid is also very important in the prawn diet. It notonly affects the survival rate, but also promots the content of cholesterone in muscleof the prawn. In this test, when the diet contains soyabean oil 3%,fish oil 2.5% andcholesterone 0.5%, the optimum content of phospholipid is 3% satisfied the mutr-itional requirement.
