and concise order. It usually relates to the feeding of va- 

 rious classes of animals at different ages and from which 

 different kinds of performance are required. Although the 

 form of expression in those standards varies, they usually 

 contain the following: 



1. The total dry organic substance, 



2. The total digestible nitrogenous substance, 



3. The total digestible non-nitrogenous substance 

 which includes, 



(a) The total digestible carbohydrates including fi- 

 bre ; and, 



(b) The total digestible fat. 



4. The total nutritive substance, and, 



5. The nutritive ratio resulting. 



The following table of feeding standards is taken from 

 that portion of "First Principles of Agriculture" credited to 

 the author and published in 1891. It is virtually identical 

 with the standard given by Armsby in his book "Cattle 

 Feeding."
