摘要： The study investigated the effects of different dietary lipid sources on the growth performance, carcass composition, and blood parameters of juvenile Chinese sturgeon, Acipenser sinensis. Seven iso-nitrogenous and iso-energetic diets containing different lipid sources were prepared, i.e. fish oil (FO), soybean oil (SO), groundnut oil (GO), rapeseed oil (RO), corn oil (CO), pork lard (PL), or fish oil: pork lard (1:1, FPL). Each experimental diet was fed to triplicate treatments of eight Chinese sturgeon juveniles with initial weights of approximately 47.5g in indoor tanks for 10weeks. The FO, SO, and CO treatments had significantly higher weight gain and specific growth rates than the other treatments. Muscle lipid content of the FO treatment was significantly higher than that of the PL treatment, but significantly lower than that of the SO treatment (P<0.05). The PL treatment had the lowest liver lipid content. Plasma cholesterol and triglyceride concentrations in the CO, FO, and SO treatments were significantly lower than those in the GO, PL, and FPL treatments. The activities of alanine aminotransferase and aspartate transaminase in the FO, GO, and CO treatments were lower than those in the SO, PL and FPL treatments (P<0.05). This study revealed that the use of lipid sources for juvenile A.sinensis can be chosen in the order of FO, followed by CO and SO; GO was the least suitable lipid source for juvenile Chinese sturgeons.
