Narrow Ration. — A narrow ration is one in which the pro- 

 portion of protein is large as compared to the carbohydrates. A 

 ration having a nutritive ratio less than i : 5.5 is considered 

 narrow.

The protein in the above ration is high as compared to the 

 carbohydrates. Nitrogenous ration is another name sometimes 

 applied to a narrow ration because of the predominance of 

 nitrogenous substances (protein). 



Wide Ration. — A wide nutritive ratio is one where the pro- 

 portion of carbohydrates is large as compared to the protein. 

 Such a ration has a nutritive ratio of more than i : 8.0

This style of ration is sometimes called carbonaceous on ac- 

 count of the high proportion of carbohydrates, but the term 

 is incorrect because protein as well as carbohydrates contains 

 carbonaceous compounds.
