      摘要
    • 摘要:
      目的 探讨丙氨酰-谷氨酰胺(Ala-Gln)和γ-氨基丁酸(GABA)对建鲤Cyprinus carpio var.jian生长、饲料利用及肌肉营养成分的影响。
      方法 在建鲤配合饲料中添加不同比例Ala-Gln和GABA，配成7种等氮(质量分数为32%粗蛋白质)、等能(17.0 MJ·kg-1)饲料，以添加Ala-Gln和GABA对建鲤生长最适添加量(6.0 g·kg-1Ala-Gln、90 mg·kg-1GABA)的添加组添加比例为100%，在此基础上等比例缩减和增加，Ala-Gln和GABA的添加梯度分别为0(0 g·kg-1Ala-Gln、0 mg·kg-1GABA)、20%(1.2 g·kg-1Ala-Gln、18 mg·kg-1GABA)、40%(2.4 g·kg-1Ala-Gln、36 mg·kg-1GABA)、60%(3.6 g·kg-1Ala-Gln、54 mg·kg-1GABA)、80%(4.8 g·kg-1Ala-Gln、72 mg·kg-1GABA)、100%(6.0 g·kg-1Ala-Gln、90 mg·kg-1GABA)、120%(7.2 g·kg-1Ala-Gln、108 mg·kg-1GABA)，共7组。饲喂初始体质量为45.59 g建鲤8周。
      结果 与对照组相比，饲料中添加Ala-Gln和GABA的添加组，建鲤平均增质量率和特定生长率均显著提高(P < 0.05)；其中60%添加组(3.6 g·kg-1Ala-Gln、54 mg·kg-1GABA)的饲料效率、蛋白质效率及肌肉中粗蛋白质含量均显著高于不添加的对照组(P < 0.05)，其他各组之间差异不显著(P>0.05)。
      结论 饲料中添加Ala-Gln和GABA在一定程度上促进了建鲤幼鱼生长、饲料利用和肌肉蛋白质的合成，其中以3.6 g·kg-1Ala-Gln、54 mg·kg-1GABA组的效果最佳。

       

      Abstract:
      Objective To evaluate the influence of propylene ammonia acyl-glutene (Ala-Gln) and γ-aminobutyric acid (GABA) on growth, feed utilization, and muscle composition of Jian carp, Cyprinus carpio var.jian.
      Method Seven isoenergetic(17.0 MJ·kg-1) and isonitrogenous (32% crude protein) feeds were formulated with varying proportions of Ala-Gln and GABA. With the 100% ratio corresponding to the optimum concentraion of Ala-Gln and GABA for Jian carp, growth (6.0 g·kg-1Ala-Gln, 90 mg·kg-1 GABA), the seven groups of feeds were formulated by scaling up or down to 0(0 g·kg-1Ala-Gln and 0 mg·kg-1GABA), 20%(1.2 g·kg-1Ala-Gln and 18 mg·kg-1GABA), 40%(2.4 g·kg-1 Ala-Gln and 36 mg·kg-1GABA), 60%(3.6 g·kg-1Ala-Gln and 54 mg·kg-1GABA), 80%(4.8 g·kg-1Ala-Gln and 72 mg·kg-1GABA), 100%(6.0 g·kg-1Ala-Gln and 90 mg·kg-1GABA), and 120%(7.2 g·kg-1Ala-Gln and 108 mg·kg-1GABA). Jian carps with an initial individual body mass of 45.59 g were fed for 8 weeks.
      Result Compared with the 0 control group, all the other feed groups with added Ala-Gln and GABA significantly increased the average mass gain rate and the specific growth rate for Jian carps(P < 0.05). The 60% groups resulted in significantly higher feed efficiency, protein efficiency, and crude protein content in muscle compared to the control group (P < 0.05), while there was no significant difference among other groups (P>0.05).
      Conclusion Adding Ala-Gln and GABA to the feed promoted the larval growth, feed utilization and protein synthesis in the muscle for Jian carps, and the 60% group with 3.6 g·kg-1Ala-Gln and 54 mg·kg-1 GABA had the best effects.
