FOOD NUTRIENTS 



gen-free extract and i.i pounds of fat. By multi- 

 plying these amounts by the figures representing 

 the digestibility for each constituent respectively, 

 the amount of each digestible nutrient will be ob- 

 tained. This is done as follows : 



Digestible Digestible 



Constituent Composition Coefficient Nutrient 



Protein 3.8 x 45 = 1.7 



Crude Fiber 19.7 * x 67 = 13.2 



Nitrogen-free extract 31.5 x 61 = 19.2 



Fat 1.1 x 62 = 0.7 



The total digestible nutrients may be determined 

 in this manner for each feeding stuff. Crude fiber 

 and nitrogen-free extract, being used for the same 

 purpose after absorption, may be included as a 

 single group. They stand for the same thing, and 

 from now on will be grouped under the term car- 

 bohydrates. In the table below the feeding stuffs 

 previously mentioned are listed and the total diges- 

 tible nutrients of each are shown.
