Abstract
SUMMARY: The in vitro dry-matter digestibilities (IVDMD) of three rations containing different proportions of hay and a mixed concentrate (pellets) were each determined by fermenting the feeds with inocula obtained from rumen contents of sheep fed on either the hay, hay and pellets, or pellets. These inocula had no significant effect on the IVDMD which averaged 60·9, 68·8 and 77·8% for the hay, hay and pellets, and pellets respectively.
