摘  要：
水温为14~18.5℃,分别在基础饲料(对照组)中添加不同含量的果寡糖(0.1%、0.2%、0.5%)和甘露寡糖(0.1%、0.2%、0.4%),研究果寡糖和甘露寡糖对大菱鲆幼鱼[体质量为(20.53±0.10)g]生长性能和血清生化指标的影响,试验共进行42d。试验结果表明,果寡糖可以使大菱鲆幼鱼的质量增加率、特定生长率、能量表观消化率和尿素含量显著增加(P<0.05),饲料系数降低;随着果寡糖添加量的增加,总蛋白含量逐渐升高(P>0.05)。添加甘露寡糖后,大菱鲆幼鱼的饲料系数、摄食率、粗蛋白、干物质表观消化率和总蛋白含量随其添加量的增加逐渐提高(P>0.05),甘油三酯含量逐渐降低(P>0.05);质量增加率、特定生长率、能量表观消化率和尿素含量显著增加(P<0.05)。在本试验条件下,果寡糖和甘露寡糖对大菱鲆幼鱼起到一定的促生长作用,并能提高对营养物质的吸收,促进蛋白质和脂类代谢。

摘  要：
A 42-day trial was conducted to study the influences of fructo-oligosaccharides and mannan oligosaccharides on growth performance and serum biochemical parameters in juvenile turbot Scophthalmus maximus weighing(20.53±0.10)g in a lab at water temperature of 14—18.5℃.The juveniles were fed the diets containing fructo-oligosaccharides at a rate of 0%(as control group),0.1%,0.2%and 0.5%and mannan oligosaccharides at a rate of 0%(control group),0.1%,0.2% and 0.4%.The results showed that the fructo-oligosaccharides led to significant increase in weight gain rate,specific growth rate,energy apparent digestibility and serum urea content,and to lower food conversion ratio(P<0.05).The total protein content was found to be elevated with increase in mannan oligosaccharides level(P>0.05).The juveniles fed the diets containing mannan oligosaccharides had higher food conversion ratio,food intake,and crude protein and dry matter apparent digestibility as well as the total protein content(P>0.05),and lower triglyceride content(P>0.05).The weight gain rate and specific growth rate,energy apparent digestibility and serum urea content were increased with increase in mannan oligosaccharide level(P<0.05).It is concluded that both fructo-oligosaccharides and mannan oligosaccharides promote the growth of the juvenile via improvement of nutritional absorption and metabolism of protein and lipid.
