The effects of dietary fish oil on hepatic high density and low density lipoprotein receptor activities in the rat

AbstractRats were fed either a standard ration diet or that diet supplemented with 8% by wt of a marine fish oil or safflower oil. After 10 days, plasma triacylglycerols, total cholesterol, high density lipoprotein (HDL) cholesterol, hepatic cholesterol and fatty acid synthesis and hepatic low density lipoprotein (LDL) receptor activity were significantly depressed while HDL receptor activity was significantly increased in rats fed fish oil. Fish oil-induced effects on cholesterol metabolism in the rat therefore include reciprocal changes in the activities of hepatic LDL and HDL receptors

Soluble Wheat Pentosans Exhibit Different Anti-Nutritive Activities in Intact and Cecectomized Broiler Chickens

The role of the ceca in the anti-nutritive effect of wheat pentosans was studied in intact and cecectomized broiler chickens. Addition of wheat pentosans (equivalent to 30 g pure arabinoxylans/kg diet) depressed the digestibilities of starch, protein and fatty acids in both types of birds. Cecectomized birds were less efficient (

Non-Starch Polysaccharide-Degrading Enzymes Increase the Performance of Broiler Chickens Fed Wheat of Low Apparent Metabolizable Energy

The effect of a commercial glycanase product (Avizyme TX) on the performance of 4-wk-old broiler chickens fed wheats with low and normal apparent metabolizable energy values was studied. Controls were fed a corn-based diet. Supplementation with the enzyme product significantly (
