DETERMINATION OF DIGESTIBILITY CO-EFFICIENTS                        307

THE DIRECT ESTIMATION OF DIGESTIBILITIES OF BOTH STRAW AND CAKE BY THE
                                          GRAPHICAL METHOD.

As already stated, the unsatisfactory results obtained by the existing methods
have led to its trial.

It is necessary to state here that this method was apparently given some trial
by Warth [ 1929 ] on the aspect of protein digestion of concentrates. It has
however been carried out in the present case on a rather more comprehensive scale
including all the individual components comprising the roughage and concen-
trate. A brief description of the method as here used is given in the following.
