The digestibility of dried yeast

At the close of the digestion experiments described in the foregoing communication a quantity of the “seeds” hay of known composition and digestibility remained which was sufficient for one further experimental period. The opportunity was therefore taken of determining the digestibility of dried yeast, a by-product of the fermentation industries which is being produced in increasing quantities and which has attracted notice since the outbreak of war.
