*To obtain the total nutrients, the fat was multiplied by 2^4 because 

 fat contains 2*4 times as much energy as an equal weight of carbohy- 

 drates or protein. 



average of 12.65 pounds; the fat varied from .75 to 1.17 pounds, 

 with an average of .93 pounds. In Lot 2 the protein varied 

 from 1.3 1 to 2. 1 1 pounds, with an average of 1.75 pounds; the 

 carbohydrates varied from 12.90 to 20.32 pounds, with an aver- 

 age of 17.28 pounds; the fat varied from .65 to 1.05 pounds, 

 with an average of .89 pounds. This shows that in producing 

 a pound of fat 24 per cent more total nutrients were used with 

 the poorly balanced ration. It will be noted that the difference 

 is not so great as in the case of the milk.
