Digestible Matter in Rations (Per Cent.) — Concluded. 



The amounts and proportions of digestible matter in each 

 of the two rations are identical. In calculating the above 

 rations, average digestion coefficients were taken for the 

 grains, the coefficients obtained at this station for the cotton- 

 seed feed, and in case of the hay, the coefficients obtained 

 by us for hay of similar appearance and composition. It 

 must be remembered that the above digestible material in 

 the two rations is only estimated. It is therefore quite pos- 

 sible that, had actual digestion experiments been made with 

 the cows, these figures may have been somewhat modified. 



WeigJit of Animals at Beginning and End of Experiment (Pounds). 



The cows were weighed at the same time for three con- 

 secutive days at the beginning and end of the experiment.
