摘要
在饲料中分别添加w=20%的葡萄糖、小麦淀粉、玉米淀粉、马铃薯淀粉、蔗糖、糊精,饲养初始质量为(0 78±0 01)g的南美白对虾,经过56d的生长试验,观察不同糖源对于南美白对虾的生长、成活率、机体营养组成的影响。实验结果表明,南美白对虾对不同糖源的利用表现出差异性,蔗糖组的成活率、特定生长率、饲料效率均最高;其他各组差异不显著。不同糖源对南美白对虾生长的影响依次为蔗糖>玉米淀粉>小麦淀粉>糊精>葡萄糖>马铃薯淀粉;对南美白对虾成活率的影响依次为蔗糖>马铃薯淀粉>玉米淀粉>小麦淀粉>糊精>葡萄糖。不同糖源对南美白对虾全虾蛋白质含量和水分含量的影响差异不大,但是糊精和马铃薯淀粉组的全虾脂肪含量明显低于其他各组,蔗糖组的全虾灰分与其他各组都没有显著性差异,葡萄糖组最高,糊精组最低。
Pacific white shrimp (Penaeus vannamei)(0.78g average weight) were fed with six diets for 8 weeks to observe the effects of different carbohydrates on the growth, survival rate and nutrient composition. Six formulated diets all contained about 20% carbohydrate content with different carbohydrate sources: glucose, cornstarch, wheat starch, potato starch, sucrose and dextrin. Different carbohydrate sources took significant difference influence on the growth of shrimp when its other requirements were met. The results showed that the shrimp fed with sucrose had the best effect on survival rate and SGR. Cornstarch and wheat starch had lower effect on survival rate and SGR than sucrose. And there was the lowest survival rate and SGR in glucose. Different carbohydrate sources had no significant influence on the crude protein of body, but had influenced on the crude fat, ash and moisture of body of shrimp.
