Abstract

ABSTRACT This study evaluated the effects of different sources of dietary carbohydrates on the growth, antioxidant capacity, and digestive enzyme activity, and carbohydrate metabolic enzyme activity of Litopenaeus vannamei were evaluated. The experimental diets, including glucose, sucrose, potato starch, corn starch, and wheat starch, were fed to L. vannamei for 35 days. We found that shrimp fed on corn starch and wheat starch grew better, whereas shrimp fed on wheat starch showed the highest digestive enzyme activity. In addition, the starch group showed higher total superoxide dismutase (T-SOD) activity and lower malondialdehyde (MDA) content. The glucose, sucrose, starch, and corn starch fed shrimp showed significantly higher levels of hepatopancreatic hexokinase (HK), whereas those fed on glucose and potato starch also showed significantly higher levels of hepatopancreatic phosphofructokinase (PFK) activity. The activities of phosphoenolpyruvate carboxykinase (PEPCK) and glucose 6-phosphatase (G6Pase) were higher in shrimp fed on glucose, whereas higher fructose 1,6-bisphosphatase (FBPase) activity was observed in shrimp fed on wheat starch, glucose, and sucrose. The insulin content of shrimp in the glucose group and potato starch group was higher, whereas that of the glucose group was higher than that of the potato starch group. In brief, the addition of wheat starch to the diet plays a positive role in the growth, glycolysis, gluconeogenesis, and antioxidant activity of shrimp, and is a promising choice for juvenile shrimp culture.

日粮碳水化合物来源对凡纳滨对虾生长性能、糖代谢和消化酶活性的影响
摘要本研究评估了不同碳水化合物来源对凡纳滨对虾生长、抗氧化能力和消化酶活性的影响,并评估了碳水化合物代谢酶活性。实验日粮包括葡萄糖、蔗糖、马铃薯淀粉、玉米淀粉和小麦淀粉,分别饲喂凡纳滨对虾35天。我们发现,喂食玉米淀粉和小麦淀粉的虾生长得更好,而喂食小麦淀粉的对虾表现出最高的消化酶活性。此外,淀粉组总超氧化物歧化酶(T-SOD)活性较高,丙二醛(MDA)含量较低。葡萄糖、蔗糖、淀粉和玉米淀粉喂养的虾显示出显著更高水平的肝胰腺己糖激酶(HK),而葡萄糖和土豆淀粉喂养的对虾也显示出显著较高水平的肝胰磷酸果糖激酶(PFK)活性。在喂食葡萄糖的虾中,磷酸烯醇丙酮酸羧激酶(PEPCK)和葡萄糖-6-磷酸酶(G6Pase)的活性较高,而在喂食小麦淀粉、葡萄糖和蔗糖的虾中观察到较高的果糖1,6-双磷酸酶(FBPase)活性。葡萄糖组和马铃薯淀粉组虾的胰岛素含量较高,而葡萄糖组的胰岛素含量高于马铃薯淀粉组。总之,在日粮中添加小麦淀粉对虾的生长、糖酵解、糖异生和抗氧化活性具有积极作用,是幼虾养殖的一个很有前途的选择。
