| 摘 要： | 为了解2种状态(饥饿和复投喂)下投喂3种糖源对凡纳滨对虾仔虾生长、虾体组成成分、代谢指标的影响，实验共5个处理，分别为饥饿组S0、对照组C、实验组S1、S2、S3(在基础饲料中糖源分别为：葡萄糖、蔗糖、玉米淀粉)。实验选取体质量为(1.84±0.23) g的凡纳滨对虾仔虾用方形纱制网兜独立喂养，进行为期12 d的饥饿实验后继续复投喂12 d。结果显示，饥饿后仔虾体组成成分及相关酶脂肪酶(LPS)、磷酸果糖激酶(PFK)、已糖激酶(HK)、谷氨酰胺合成酶(GS)]差异显著；仔虾肝糖原、肌糖原均呈现出反复升降的过程，饥饿8 d后肝糖原降到最低值，肌糖原短暂回升后显著下降。复投喂4 d后S3组增重率最高，实验各组间无显著差异，均低于C组；全虾水分、全虾粗灰分、肌糖原含量无显著差异；S1、S2组虾体粗脂肪含量显著高于S3组；肝糖原、肌糖原均有回升，S1组肝糖原显著低于其他组。复投喂12 d后，S3组LPS活性、HK活性显著高于其他各实验组，GS、PFK含量实验组间无显著差异。研究表明，凡纳滨对虾仔虾饥饿过程中糖原和脂肪先于蛋白质被动用供能；复投喂出现部分补偿生长效应，玉米淀粉作为糖源饲料对凡纳滨对虾仔虾期恢复生长效果最佳。

| Abstract: | The present study investigated the effect of two states (hunger and refeeding) on the growth performance, body composition and related metabolism of Litopenaeus vannamei. There were 5 treatments in the experiment, which were starvation group (S0), control group (C), experimental group named S1, S2 and S3 (sugar sources: glucose, sucrose, cornstarch, respectively), while the juvenile L. vannamei (1.84±0.23) g continue to feed for 12 days after 12 days of starvation. The results showed that starvation affected body composition of juvenile L. vannamei postlarvae and related enzymes lipase (LPS), phosphofructokinase (PFK), hexokinase (HK), glutamine synthetase (GS)] significantly; shrimp liver and muscle glycogen were repeated movements, after 8 d starvation glycogen dropped to the lowest value, muscle glycogen decreased significantly after a brief rebound. The weight gain in S3 group was the highest after refeeding 4 days, the experimental groups were lower than the C group significantly and it was not significant among the experimental groups. The liver glycogen, muscle glycogen content in S1 was significantly lower, The activity of LPS and HK increased greatly during the early days of refeeding, and there was no significant difference in the content of LPS and PFK between the experimental groups. After refeeding 12 days, the activity of LPS and HK in S3 was significantly higher the other experimental groups; there was no significant different between GS and PFK content in experimental groups. The study showed that the glycogen and fat were first used for energy supply during the starvation of L. vannamei, and the refeeding was partly compensated for growth, and the effect of corn starch sugar source feed was the best. |
