Composition and physicochemical properties of experimental diets containing either 500 g/kg rapeseed meal or corn distillers dried grain with solubles (DDGS), with or without inclusion of β-glucan-extract (β-GLUC) or retrograded tapioca (RG)*,†.

Apparent ileal and total tract digestibility of DM and nutrients in growing pigs fed diets containing either 500 g/kg rapeseed meal or corn distillers dried grain with solubles (DDGS), with or without inclusion of β-glucan-extract (β-GLUC) or retrograded tapioca (RG)*,†.

Mean retention time in the stomach and small intestine of solid and soluble digesta fractions and viscosity of ileal digesta in growing pigs fed diets containing either 500 g/kg rapeseed meal (RSM) or corn distillers dried grain with solubles (DDGS), with or without inclusion of β-glucan-extract (β-GLUC) or retrograded tapioca (RG)*,†.

Average chromium to cobalt ratio in ileal digesta of pigs collected during 12 h after feeding a pulse dose of Cr2O3 and Co-EDTA markers.
Digesta samples were collected at 45, 90, 180, 270, 360, 540, and 720 min after feed consumption. Baseline (1.0) represents Cr:Co in the pulse dose. Pigs were fed diets containing 500 g/kg rapeseed meal (RSM) or distillers dried grains with solubles (DDGS) as the only fiber source, with or without inclusion of β-glucan-extract (β-GLUC) or retrograded tapioca (RG). Error bars indicate SEM. An asterisk indicates differences from baseline (*P < 0.05).

Undegraded Non-starch polysaccharides (NSP) in feces from growing pigs.
Pigs were fed diets containing 500 g/kg rapeseed meal (RSM) or distillers dried grains with solubles (DDGS) as the only fiber source, with or without inclusion of β-glucan-extract (β-GLUC) or retrograded tapioca (RG). Error bars indicate SEM for total NSP. Asterisks indicate differences from control diet for total NSP P = 0.01; **P < 0.001). Non-starch polysaccharides are separated in β-glucans, residual glucosyl polysaccharides, arabinosyl, xylosyl, uronyl, and other non-glucosyl polysaccharides constituent sugars, where residual glucosyl polysaccharides are calculated as total glucosyl minus free glucose and glucosyl from starch and β-glucans, representing cellulose and other glucosyl-containing NSP.

Arabinosyl:xylosyl and uronyl:xylosyl ratios in diets, ileal digesta, and feces from growing pigs.
(A) Mean molar arabinosyl:xylosyl ratio. (B) Mean molar uronyl:xylosyl ratio. Pigs were fed diets containing 500 g/kg corn distillers dried grains with solubles as the only fiber source, with or without inclusion of β-glucan-extract (β-GLUC) or retrograded tapioca (RG). Data labels indicate number of replicate observations. Error bars indicate SEM. Asterisks indicate differences (*P = 0.05; **P < 0.01).
