The fuel values of the rations were computed by multiplying 
the number of pounds of digestible protein and carbohydrates by 
1,860 and the number of pounds of digestible fat by 4,220 and 
taking the sum of the products as representing the number of 
calories of available energy in the ration. 

+ Assumed. 
t Computed from the assumed digestibility of the ingredients used in the grain 
mixture.
