Summary

The effect of gradually replacing barley with swedes or potatoes on intake of digestible dry matter and on the volatile fatty acid (VFA) composition of liquor was measured in an experiment with eight female and four castrated male sheep approximately six months old. The total intake of digestible dry matter was greatest when rolled barley was given at two-thirds of estimated maximal intake and roots given ad libitum. The intake of digestible dry matter was reduced to 80% of the highest intake when all the barley was substituted with swedes and to 70% of the highest intake when all the barley was substituted with potatoes. Replacing barley with roots had little or no influence on VFA composition.
