¹Neutral detergent fiber assayed with heat-stable amylase and expressed exclusive of residual ash.

²Acid detergent fiber expressed exclusive of residual ash.

³Acid detergent lignin.

⁴Inositol phosphate (InsP) isomers not included in this table were not detectable or below the limit of quantification.

⁵Asp, Asn and Glu, Gln, respectively, were not distinguished because the side groups of Asn and Gln are lost during acid hydrolysis (Fontaine, 2003).
