Fig. 8. Mean 12- and 96-h in vitro degradabilities of cellulose (cell), hemicellulose (hemi), and pectin (a and b, respectively) and total cell wall polysaccharide degradability of three alfalfa clones (c and d, respectively) from Internode 7 harvested at different stages of maturity after fermentation with rumen microorganisms. Bars represent one standard error of the mean. Absence of error bars indicates that the standard error interval was smaller than the size of the data symbol.
