研究了不同水平的磷脂（PL）和胆固醇（CH）对三疣梭子蟹（Portunus trituberculatus）幼蟹生长、蜕皮及脂肪酸组成的影响。试验共设6个日粮，分别含3个PL水平（0、10和20 g/kg）和2个CH水平（2和8 g/kg）。梭子蟹幼蟹（3.48 ± 0.02g/蟹）饲养8周。体重增加（WG）显著（p.05）。日粮处理对换羽率、蛋白质效率和饲料效率影响不显著（p> 0.05）。血清总胆固醇（TCH）随日粮PL水平的增加而显著升高（p> 0.05）.在含2g/kg CH的饲料中添加PL，蟹体C20：4 n-6和C20：5 n-3含量增加。PL和CH之间的相互作用被观察到对某些饱和和不饱和脂肪酸的身体浓度。
The objective of this study was to evaluate the effects of different phospholipids (PL) and cholesterol (CH) levels on the growth, moulting and fatty acid composition of juvenile swimming crab, Portunus trituberculatus. Six diets were designed to contain three PL levels (0, 10 and 20g/kg) and two CH levels (2 and 8g/kg). Juvenile swimming crabs (3.48 +/- 0.02g/crab) were reared for 8weeks. The weight gain (WG) was significantly (p.05). The moulting frequency (MF), protein efficiency ratio (PER) and feed efficiency ratio (FCR) were not significantly (p>.05) affected by the dietary treatments. The serum total cholesterol (TCH) significantly (p>.05) increased with increasing dietary PL level. The C20:4n-6 and C20:5n-3 content of the whole body of crabs increased with the addition of PL to the diet containing 2g/kg CH of diet. An interaction was observed between PL and CH on certain saturated and unsaturated fatty acid concentrations of body.
