inthefucoidan-supplemented diets would suggest that a proportion of the supplemented fucoidan is escaping hydrolysis in the foregut and passing in to the colon for bacterial fermentation. Saccharolytic species of bacteria such as Lactobacilli spp. take part in the breakdown of complex carbohydrates.25 Inaddition,pigsofferedfucoidan-supplemented diets increased the concentration of total volatile fatty acids in the proximal and distal colon which indicates an increased flow of ileal substrate into the hindgut23 and reduced branched-chain fatty acids.
