¹ Values are means ± SEM, n = 5 pigs. Carbohydrates, except as noted, were analyzed in duplicate by gas chromatography. ß-glucan glucose was measured in duplicate by an enzymatic-colorimetric assay (Shinnick et al. 1988 ).

² ND = not determined.

³ Non-ß-glucan-derived glucose calculated as the difference between total glucose and ß-glucan-derived glucose.
