| 摘 要： | 选用270尾初始体重（12．97±0．18）g的德国镜鲤幼鱼，随机分为6组，每组3个重复，每个重复15尾。I组为对照组，饲喂基础日粮，Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ组为试验组，分别饲喂在基础日粮中添加丙氨酰-谷氨酰胺（Aln—Gin）0．25，0．5，0．75，1．0和1．5％的13粮，试验期为12周，观察Ain—Gin对镜鲤血清生化指标及营养组成的影响。结果显示：与对照组相比，各试验组血清总蛋白和球蛋白含量显著升高（P〈0．05）；添加高剂量Aln—Gin（1．5％）试验组血清白蛋白显著提高（P〈0．05）；各组的血清谷丙转氨酶、谷草转氨酶及碱性磷酸酶活性差异不显著；各试验组全鱼粗蛋白质含量升高，其中Ⅳ、Ⅴ和Ⅵ组显著升高（P〈0．05）；各组的粗水分、粗脂肪和灰分含量差异不显著。结果表明，日粮中添加一定量的Aln—Gin能够显著促进鲤鱼幼鱼营养代谢，提高全鱼蛋白含量。

| Abstract: | A 12 weeks feeding trial was conducted to study the effect of dietary alanyl-glutamine （Aln-Gln） on serum biochemical indices and body composition of juveniles German mirror cap （Cyprinus carpio L）. Two hundred and seventy carp with an average body weight of （12.97 ± 0.18）g was randomly allocated into 6 groups with 3 replicates of 15 fish.Group Ⅰ,as the control group,was fed with the basal diet, while group Ⅱ,Ⅲ,Ⅳ,Ⅴ and Ⅵ ,as the trial groups,were fed with the basal diet added with 0.25, 0.5, 0.75, 1.0 and 1.5% Aln-Gln respectively. The results showed that compared with the control group, serum TP and GLB levels were improved significantly with increasing dietary Aln-Gln supplemental levels （P〈0.05）. Adding 1.5% of Aln-Gln in diet improved serum ALB levels （P〈0.05）. Serum ALP, GPT and GOT activities were not influenced by supplementation of different levels of Aln-Gln （P〉0.05）. Whole-fish protein content was increased and showed a significant increase in group Ⅳ, Ⅴ and Ⅵ（P〈0.05）, while no difference was observed in moisture, lipid and ash between treatments （P〉0.05）. In conclusion, nutrition metabolism and whole fish protein content could be improved by adding Aln-Gln. |
