Abstract: (9495 Views)
A 12-week feeding trial was carried out in 500 L fiberglass tanks to evaluate the effect of dietary choline at 0, 2, 4, and 8 g kg -1 levels on growth rate, body composition and total liver lipid of juvenile Acipenser baerii (37.67±0.67 g). A semi purified basal diet was formulated using vitamin free casein and wheat gluten as a protein source, a mixture of animal and plant oils as a lipid source and dextrin as a carbohydrate source. Four isonitrogenous (40% protein) and isoenergetic (18 MJ kg-1) diets were prepared and fed to the fish three times daily to apparent satiation. Weight gain, feed conversion ratio (FCR), specific growth rate (SGR) and protein efficiency ratio (PER) were significantly affected by dietary choline (p<0.05). The best growth performance was observed in fish fed diets containing 2 and 8 g kg -1 choline (p<0.05). Fish fed with 2 and 4 g kg -1 choline showed higher lipid content compared with the control diet (p<0.05), but not significantly different in body protein (p>0.05). Total lipid of liver and plasma, plasma cholesterol, triglyceride and phospholipids levels showed an increasing trend with increasing levels of dietary choline, but not significantly different among treatments (p>0.05). Based on the results, we recommend adding a 1.5 gkg-1 choline to commercial diet of juvenile Acipenser baerii.
