以饲料中添加36％鱼粉作为对照组,用菜籽粕分别替代饲料配方中10％～50％的鱼粉,配成5种等氮等能试验饲料,饲喂凡纳滨对虾,研究不同替代比例对凡纳滨对虾生长性能和虾体氨基酸组成的影响.试验结果表明,饲养56d后,随着菜籽粕替代鱼粉比例的增加,对虾的质量增加率下降,但仅50％替代比例试验组的质量增加率为1542.74％,显著低于对照组(2066.07％,P＜0.05)；质量增加率(y)和菜籽粕实际添加量(x)的回归方程为y=-0.8674x2+12.917x +2031.7(r2=0.9081).通过拐点法计算得出的菜籽粕最适添加量为7.37％(换算成替代比例为12.70％),在99％的置信水平下,3.17％～22.48％的替代是完全可行的.菜籽粕替代鱼粉饲...

A 56 d feedingtrial was conducted to evaluate the effects of replacement of fish meal by rapeseed meal in practical diets on growth performance and amino acid profile of Pacific whiteleg shrimp Litopenaeus vannamei. In six isonitrigenous diets containing 36.5 % protein and 7.5 % lipid （Ctrl）, fish meal was replaced by rapeseed meal at five inclusion levels of 10% （RM1）, 20% （RM2）, 30% （RM3）, 40% （RM4） and 50% （RMS）. The control diet contained 36% fish meal. The shrimp juveniles with initial body weight of 0. 247 g were randomly stoc...
