　　以初始体重(11.76±0.20)g的黄鳝(Monopterus albus)为试验对象，肉骨粉等氮替代0％(对照)、12.5％、25％、37.5％和50％的鱼粉，共5组，各组3个重复，添加晶体赖氨酸和晶体蛋氨酸以保持各组赖氨酸和蛋氨酸平衡，养殖实验进行8周，研究肉骨粉替代鱼粉对黄鳝生长、消化酶活性、血清生理生化指标及体成分的影响.方差分析表明，肉骨粉替代水平在25％范围内对黄鳝生长及饲料效率无显著影响；37.5％、50％替代水平显著降低鱼体生长、饲料效率与蛋白利用率(P＜0.05).折线模型分析表明，肉骨粉适宜替代水平为33.5％.脏体比与肝体比随肉骨粉含量的升高显著升高(P＜0.05).胰蛋白酶与脂肪酶活性在对照...

　　A 8-week feeding experiment was conducted to investigate the effects of replacement of fish meal(FM) by meat and bone meal(MBM) in diets on growth,intestinal digestive enzyme activities,plasma chemistry and body composition in juvenile rice field eel(Monopterus albus)(initial mean body weight of 11.76±0.20 g,mean±SEM).Five isonitrogenous(400 g/kg crude protein) and isolipidic(80 g/kg crude lipid) diets replacing 0(control diet),12.5,25,37.5 and 50% FM protein by MBM protein were formulated,in which crystallized lysine and methionine were ...
