Net-Energy Values of Feeding Stuffs 
479 
Hominy Feed. —Average metabolizable energy per kilogram of dry 
matter, computed in a manner explained in example 2 = 3,522 Calories. 
Heat increment per kilogram of dry matter from periods 2 and 3 
(greatest and least amounts of feed), computed in a manner illustrated 
in Table IV, example 2 = 1,226 Calories (Table X). Average net- 
energy value, 3,522 — 1.226 = 2.296 Calories. 
The computation of the maintenance requirement of the animal, 
and of the net-energy values of the mixed hay, and of the hominy 
feed, according to the new method, is as set forth in Tables XI, 
XII and XIII, respectively.
