Sept. 17. 1917 Energy Values of Hominy Feed and Maize Meal 603 



to feed. The results upon the concentrates were computed upon the 

 assumption of unchanged utilization of the hay as computed from the 

 three periods on hay alone. 



Each period comprised 21 days, of which 11 were regarded as pre- 

 liminary, while the visible excreta were collected quantitatively for the 

 remaining 10. The complete balance of matter and energy was deter- 

 mined with the respiration calorimeter on the eighteenth and nineteenth 

 days of each period. A list of the periods and rations fed and of the 

 average live weights of the animals is contained in Table VII.

PERCENTAGE DIGESTIBILITY 



The digestibility of the total rations and that of the grain as computed 

 on the assumption that the hay consumed with it had the digestibility 

 shown by the true average of the periods on hay alone was as shown in 

 Table VIII.
