  1. aCWD: In vitro cell wall digestibility determined as the difference in neutral detergent fiber content before and after sample incubation in rumen liquor for 48 h relative to neutral detergent fiber content prior to incubation
  2. bSignificance of differences between entries as determined by ANOVA; p < 0.05 (*), p < 0.01(**), and p < 0.001(***), NS indicates non-significant differences
  3. cLeast significant differences of means (5 % level)
