Dietary Lactosucrose Decreases Hepatic and Plasma Lipid Contents in a Marine Teleost, Red Sea Bream Pagrus major

抄録

The aims of this study were to confirm the effects of dietary lactosucrose (LS), a fermentable oligosaccharide, on plasma and liver lipid levels in red sea bream. Fish were assigned to two groups and fed either a commercial diet or a commercial diet supplemented with 0.24% LS for two months. Fish fed LS had lower liver lipid contents than did control diet-fed fish (P<0.001). Levels of plasma cholesterol and triglyceride but not HDL-cholesterol in fish fed LS were significantly lower than in control fish (P<0.001). The above results indicate that the dietary fermentable saccharide LS affected lipid metabolism in this fish.
