TABLE NUMBER 2. 



WHAT DOES THE CHEMICAL ANALYSIS MEAN? 



In a feed analysis the following determinations are usually made: 

 protein, fat, carbohydrates, ash, moisture and crude fiber. 



Protein is determined by finding the percentage of total nitrogen 

 and multiplying this by the factor 6.25, since it has been found 

 that the average proteins contain 16 per cent nitrogen. While this 

 includes small amounts of certain other compounds which contain 

 nitrogen, for all practical purposes it is sufficiently accurate. Pro- 

 tein, then, is made up of the compounds in the feed which con- 

 tain nitrogen.
