By the term nutritive ratio ^ is meant the proportion which the 

 protein bear to the starch equivalent of the nitrogen-free extract, 

 fiber and fat in the digestible portion of any food-stuff, the protein 

 being taken as 1. This starch equivalent is calculated by the addi- 

 tion of the quantities of digestible nitrogen-free extract and fiber 

 to two and one-fourth timefii the quantity of digestible fat; this in- 

 crease in the case of the fat being due to its exceptional heat produc- 

 ing power, to which reference has already been made. 



The results of many decades of farm experience and of recent ac- 

 curate scientific investigations show that the value of a ration to 

 produce a specific result, such as the development of the young 

 animal, the production of lean meat, or of fat, the enlarged or con- 

 tinued flow of milk, or, especially, working capacity, depends very 

 materially upon the nutritive ratio of the food consumed. 



As illui&trations of the ratios found in foods that experience has 

 proven to ])ossess especial value for the several ])urposes above men- 

 tioned, the following may be cited:
