Abstract
Summary
Cellulose digestion determined by the in vitro rumen fermentation technique was used as a criterion to detect the presence of metabolic inhibitor (s) in various fractions of orchardgrass. The metabolic inhibitor is extractable with hot detergent, hot alkali-detergent, and azeotropic solution of meth-anol and acetone. The inhibitor appeared to be more concentrated in relatively low cellulose-digestibility orchardgrass than relatively high cellulose-digestibility orchard-grass.
