【摘要】 在精制饲料中添加维素B6投饲团头鲂8周，检测试验鱼血清若干生化成分的变化。结果发现，维生素B6能显著降低血清甘油三酯、总胆固醇和葡萄糖含量，并相应增加血清高密度脂蛋白胆固醇和白蛋白水平及α-淀粉酶活性。分析表明，饲料中添加维生素B6能促进团头纺的血清脂质代谢及其转运，从而避免了血脂积累及营养性脂肪肝的发生。更多还原

【Abstract】 The effects of vitamin B6 in purified diets on serum components of blunt .snout bream (Megalobrama amblycephala)were studied. Fish (90～110g) were randomly divided into 3groups with 4 tanks/group and 5 fish/tank, and fed basal diet BSBD, 0. 03% B6 + BSBD and 0.3% B6 + BSBD, respectively. After 8 weeks feeding, the contents of serum triglycerides (TG),total cholesterol (TC) and glucose were significantly lower, but cholesterol in the high densitylipoprotein (HDL- C), albumin and α-amylase were higher in the fish fed B6 + BSBD than thosein the fish only fed abasal BSBD. Results suggest that supplementation of vitamin B6 in the dietsmay promote the serum lipid metabolism and transportation in blunt snout bream, and so preventthe occurrence of lipid accumulation and fatty liver caused by unbalanced diets.更多还原
