Effects of Fructo-oligosaccharides and Mannan Oligosaccharides on Growth Performance and Serum Biochemical Indices of Juvenile Turbot Scophthalmus maximus
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42 d。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。
Abstract：A 42-day trial was conducted to study the influences of fructo-oligosaccharides and mannan oli-gosaccharides 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 di-gestibility 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 grow th of the juvenile via improvement of nutritional absorption and metabolism of protein and lipid .
