Dilution of the Diet and Feed Intake in the Mouse

Abstract

MICE were fed from 3 to 6 weeks of age (weaning to mating) on diets made up by diluting a normal diet with different levels of an indigestible filler (cellulose). A greater range of diets, and younger animals, were used than in earlier work¹. The error (and labour) associated with separating waste feed and faeces when feeding pelleted food was overcome by feeding ground diets, so that waste feed could be sieved from the faeces.
