| 摘 要： | 饲料中蛋白质的含量对大菱鲆幼鱼的生长起着决定性作用，适宜的能蛋比，既有利于能量的利用，又有利于蛋白质的利用，提高了饲料的利用率。设计4个蛋白质含量梯度和4个能量梯度的16组饲料，试验证明，蛋白质含量大于42％、能蛋比小于115，鱼体日增重率明显增大，饲料系数明显降低，表现出较高的饲料效率，本研究认为大菱鲆幼鱼配合饲料适宜的蛋白质含量为42％～45％、适宜的能蛋比为92．7～102．5。 |

| Abstract: | The content of protein in feed is critical to the growth of turbot juvenile. The feed with suitable energy and protein ratio not only is able to promote the utilization of energy and protein, but also is able to improve the utilization rate of feed. In June - August 2000, orthogonal statistic method was used to study the effects of protein and energy on the growth of juvenile fish of Scophthalmus maximus L. In the L_(16)(4~3) orthogonal test, 16 groups of feed were designed, for which two ranges of the contents of protein and ratio of energy and protein of 36% - 45% and 3900 - 4500 respectively, were used. The feeding experiment lasted for 60 days. The experimental result shows that the survival rate of all experiment groups is higher than 86.7%. But with the increase of protein, the survival rate of turbot increased. If the content of protein in feed is very low, it will slow down the growth of turbot juvenile and the transition of feed. Also the effect of increasing energy is not obvious. When the content of protein is more than 42% and ratio of energy and protein less than 115, the weight growth rate/day increased obviously, and the feed coefficient rate decreased obviously. A conclusion was drawn from this experiment that the suitable content of protein is between 42 % - 45 %, and the suitable ratio energy and protein is 92.7 - 102.5. |
