(d) Digestion Experiments with Sheep. 



We have continued our digestion studies of the various 

 cattle feeds during the past year. Some of tlie work under- 

 taken is as yet inconi[)lete, and experiments are still in prog- 

 ress. Below is presented the; digestion coefficients obtained 

 with several feed stuffs. The entire data will be presented 

 at another time. By digestion coefficients is meant the per- 

 centage of the several groups of constituents composing feed 

 stuffs that the animal is capable of digesting. Thus, if wheat 

 bran contains 16 per cent, of protein, or 1(3 pounds in 100, 

 and the coefficient of the protein digestibility is 78, this 

 means that the animal can digest 78 per cent, of the 16 

 pounds, or 12.48 pounds.
