中文摘要:
      采用30%葡萄糖或玉米淀粉作为糖源的配制两种纯化饲料,饲养初始体重为(35.94±1.86)g的两组草鱼,经过为期9周的生长试验,观察葡萄糖和玉米淀粉对草鱼生长和肠系膜脂肪沉积的影响。实验结果显示:摄食葡萄糖饲料的草鱼其相对生长率、饲料效率和蛋白质效率均显著高于玉米淀粉组,而肠系膜脂肪占鱼体的百分比在葡萄糖饲料组和淀粉饲料组之间存在显著性差异,分别为1.85%±0.46%和3.56±0.45%。由此可见,葡萄糖比玉米淀粉对草鱼的生长具有更好的作用,而玉米淀粉比葡萄糖更容易引起草鱼肠系膜脂肪沉积的增加。
英文摘要:
      In the experiment, two groups of fish w ith an initial body weight of ( 35194 ? 1186) g were reared fed w ith two diets, which contain 30% glucose or corn starch for nine weeks. The results showed that the fish fed with glucose diet had significantly ( P< 0105) higher relative growth rate, feed efficiency and protein ef ficiency ratio than those fed w ith corn starch diet. In addition, significant dif ference was found in the content of mesentery fat between grass carp fed w ith glucose diet and those fed w ith corn starch diet ( 1185% ? 0146% and 3156% ? 0145%) . The results suggest that glucose in the diet has better effects on the growth of grass carp than corn starch in the diet , while corn starch w ill increase fat deposition in the mesentery of grass carp more easily than gluco se.
