a The carbohydrate equivalent is the sum of the digestible carbohydrates plus 2.25 times the digestibl e fat. 
b This is based on the initial weights of the steers. 
GAINS DURING WINTER AND SUMMER 
The initial spring and final weights and the gains and losses in weight during 
each of the three years are shown in Table IV.

® On account of dropping fractions in the average weights of the steers as given in this table, one can not 
always add the weights or gains for the 3 years, divide by 3, and obtain the average given. In no case is 
there more than 1 pound of difference
