摘要
以酪蛋白、结晶纤维素、豆油为主要原料，对蛋白质含量为39％、42％、45％；纤维素含量为2．5％、3．5％、4．5％；脂肪含量为5％、6％、7％，按正交L9（34）表对大口黑鲈进行饲喂试验。结果表明，蛋白质和纤维素三个水平间存在着显著的增重效果和蛋白质效率的差异（P＜0．05），脂肪三个水平间无论是增重，还是蛋白质利用率差异均不显著（P＞0．1）。作者建议大口黑鲈配饵中主要营养素的适宜含量为蛋白质42％左右，纤维素不高于3．5％，脂肪不低于5％。
With the development of large-mouth bass, Micropterus salmoides cultivation, artificial feed have become the key of increasing feed efficiency. The objective of this study is to determine the effects of dietary protein, fibre and fat on the growth of large-mouth bass. Accornding to orthogonalty trial Table L9(34), using casein, cellulose and soybean oil, the feeding tests were carried out for 23-29g young fish. The content of components was designed 3 levels: protein of 39%, 42%, 45%; fiber of 2. 5%, 3. 5%,4. 5%; fat of 5%, 6% and 7%. The results show that protein and fiber had signficant differences on weight gain among their levels (P<0. 05), i. e., 42% and 45% protein were better than 39%; 2. 5% and 3. 5% fiber were better than 4. 5%. Protein efficiency ratio apparent digestibility and food coefficient ratio showed further that 42% protein and 2. 5 % fiber were the best. There was no difference on weight gain and protein efficiency ratio among fat levels (P>0. 1), 5%-7% fat is also the suitable content. Thus the large-mouth bass's best compounded diet suggested is 42% protein, 2. 5 % fiber and 6% fat.
