Twelve young male pigs consumed a purified diet containing wheat bran as fiber source. Starch provided 50% of total daily energy either as a low amylose cornstarch or as a high amylose (amylomaize) starch. The pigs were given a supplement of a freeze-dried probiotic organism (Bifidobacterium longum CSCC 1941). A block crossover design was used so that at(More)
Young male pigs consumed a diet of fatty minced beef, safflower oil, skim milk powder, sucrose, cornstarch and wheat bran. Starch provided 50% of total daily energy either as low amylose cornstarch, high amylose (amylomaize) cornstarch or as a 50/50 mixture of corn and high amylose starch. Neither feed intake nor body weight gain as affected by dietary(More)
To elucidate the mechanisms underlying the plasma triacylglycerol-lowering effects of certain fish oils, livers from male rats fed either a standard commercial diet (controls) or diets supplemented with 15% (w/w) fish or safflower oils were perfused with undiluted rat blood. Rates of hepatic lipogenesis, measured by the incorporation of 3H2O into fatty(More)
Maize starch was acylated with acetic, propionic or butyric anhydride to produce the corresponding acylated starch. In the first experiment, butyrylated starch at a degree of substitution (DS) of 0.25 (i.e., 1 acyl unit per 4 glucosyl units) was fed to rats for 3 d. Cecal and distal colonic SCFA concentrations were 170 and 78% higher, respectively, in rats(More)
Four young mature male pigs, 110 to 120 kg of body weight, were maintained on a low (0.01%) cholesterol diet. A double changeover design was used so that at any time two pigs received additionally 20 g/day of saponins as a 0.33% solution in drinking water. Saponins raised concentrations of fecal bile acids and neutral sterols and increased the contribution(More)
Adult male rats were fed either ad libitum or at levels of 19 or 15 g of nonpurified diet per rat daily or subjected to 48 h of starvation followed by 24 h of refeeding. Concentrations of total and individual volatile fatty acids (VFA) in cecal contents were higher in rats fed ad libitum than in those restricted to 19 or 15 g/d. Only butyrate concentration(More)
Adult male rats were fed on diets containing 100 g dietary fibre/kg either as alpha-cellulose or wheat bran or the pericarp-seed coat or aleurone layers prepared from that bran by sequential milling and air elutriation and electrostatic separation. After 10 d, concentrations of total volatile fatty acids (VFA) in caecal fluid were significantly different(More)
Six young mature male pigs were maintained on a high fat, low fiber "Western" type diet. Substitution of ethanol for sucrose raised plasma total cholesterol, an increase that was solely due to a rise in high-density lipoproteins. Plasma triacylglycerols and apo-B concentrations were unchanged and although apo-A1 rose with ethanol, this was not statistically(More)
Male pigs were fed a low fiber beef diet (control) or that diet with additional fiber either as wheat bran, oat bran or baked beans. Total large bowel digesta and volatile fatty acid (VFA) pools were highest in pigs fed the diet with baked beans, intermediate in those fed the diets with oat bran and wheat bran and lowest in those fed the control diet. In(More)
Adult male pigs were fed on a diet containing (% of energy) fat 25 starch 55 from white rice and providing 20 g fibre/pig d (diet WR). In two other groups rice bran was added to the diet to provide 43 g fibre/d. One group received the diet unmodified (diet RB), but in another (diet RO) heat-stabilized unrefined rice oil replaced the palm oil. In a further(More)
