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-Gln)0.25,0.5,0.75,1.0和1.5%的日粮,试验期为12周,观察Aln-Gln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-Gln(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-Gln能够显著促进鲤鱼幼鱼营养代谢,提高全鱼蛋白含量。

摘  要：
A 12 weeks feeding trial was conducted to study the effect of dietary alanyl-glutamine(Aln-Gln)on serum biochemical in- dices 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 groupⅡ,Ⅲ,Ⅳ,ⅤandⅥ,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 sig- nificantly 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 groupⅣ,ⅤandⅥ(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.
