    Abstract:
    Four orchardgrass diets ranging in cell wall content from 60 to 78% were fed to sheep, and relationships among intake, digestion, passage and ruminal measurements were determined. As cell wall concentration increased, dry matter intake, digestible energy intake, dry matter digestibility and excretion rate decreased, while cell wall intake rumen volume, rumen cell wall and retention time increased. Indigestible cell wall intake was similar with each diet. It appeared that as digestible energy intake decreased, the sheep attempted to adapt by increasing ruminal ingesta volume, increasing ruminal ingesta cell wall and decreasing rate of passage; as cell wall concentration increased, indigestible cell wall limitation was manifested in decreased levels of feed and energy intake. Rate and extent of digestion appeared to be related to indigestible cell wall and appeared to be key factors in the control of cell wall turnover and feed intake.
