1 From The Feeding of Farm Animals, by E. W. Allen. Farmers' Bulletin No. 22, U. S. De- 
partment of Agriculture, Washington, D. C, 1901, p. 12. 
2 For an unworked ox of 1000 pounds weight, the standard calls for 0.78 pound of digestible pro- 
tein, 8 pounds of digestible carbohydrates, and 0.1 pound of digestible fat, which would furnish 
16,600 calories of heat and energy. When heavily worked the same ox would require, according to 
the standard, food with four times as much protein and of nearly twice the fuel value. 
' The value of food to produce heat for the body and energy for work is measured in calories 
and is calculated from the nutrients digested. The fuel value of one pound of digestible fat is 
estimated to be 4230 calories and of one pound of digestible protein or of carbohydrates about 
I860 calories. The total value of a feeding stuff is found by using these factors, the equivalents 
for the common foods being given on pages 134 and 135. 
* A calorie is the amount of heat required to raise the temperature of one pound of water about 
4 degrees.
