Abstract
Weight of rumen contents was higher in ewes on perennial ryegrass but percentage dry matter in the rumen did not differ between the 4 groups. White clover significantly increased concentration of volatile fatty acids in the rumen compared with that of animals on the grasses only. Sheep on the short-rotation ryegrass and white clover had a lower proportion of acetic acid and a higher proportion of propionic and butyric acids and higher development of rumen papillae than did those on perennial ryegrass only.
