摘要 用正交设计法设计亚油酸等必需脂肪酸三因素三水平饲料试验,结果表明中国对虾增重率、增长率、存活率受必需脂肪酸含量及其比例的影响。在本试验条件下,中国对虾对亚油酸、亚麻酸、二十碳五烯酸和二十二碳六烯酸的最适需要量分别为(%)1.95、1.09、0.20和0.37。亚油酸与亚麻酸及亚油酸与二十二碳六烯酸的最佳比例分别为1.79和5.3。对中国对虾来说,二十碳五烯酸和二十二碳六烯酸的作用大于亚油酸和亚麻酸。 The dietary test of Penaeus chinensis was designed by means of the gradient method for 18:2n-6,18:3n-3,20:5n-3 and 22:6n-3.The result shows that the weight gain rate,the length gain rate and the survival rate are influenced by the content of 18:2n-6,18:3n-3,20:5n-3 and 22: 6n-3 and the ratioes of 18:2n-6 to 18:3n-3 and 18:2n-6 to 22:6n-3.The appropriate content of 18:2n-6,18:3n-3,20:n-3 and 22:6n-3 are 1.95%,1.09%,0.20% and 0.37% respectively.The appropriate ratioes of 18:2n-6 to 18:3n-3 and 18:2n-6 to 22:6n-3 are 1.79 and 5.3 respectively.As to Penaeus chinensis,we have found that the EFA activity of 20:5n-3 and 22:6n-3 is higher than that of 18:3n-3 and 18:2n-6.The result also shows that 18:2n-6 is more effective than 18:3n-3 on the weight gain rate,and 18:2n-6 is less effective than 18:3n-3 on the length gain rate and the survival rate.
