Abstract
IN a series of investigations on dry-matter intake and fæces output of ewes, at different feed-levels, it was observed that a particular fraction of the fæces, readily dissolved by treatment with dilute acid, was closely related to the intake of dry matter. It was considered that this dissolved fæcal fraction would be unlikely to contain any high proportion of food residues already subjected to fermentation and digestion in the alimentary tract but was likely to consist largely of the more soluble parts of the metabolic fraction of the fæces. It has already been shown that this fraction bears a close relationship to dry matter intake1,2.
