ing is added to the nutritive value of the food. 
12. Digestibility little influenced by quantity.—Ordi- 
narily, digestion is but slightly influenced by big appe- 
tites. Heavy eaters are usually the most profitable ani- 
mals. Fed to their full capacity they give as good an 
account of their food as when limited to half feeds. Food 
is digested and assimilated just as completely in full as in 
half-filled stomachs. The most rapid growth, or the larg- 
est milk flow, is to be had when an animal is permitted to 
eat to its full capacity,and this is another reason why the 
ration must be palatable and attractive to taste and smell.

AAC the same feed, one will often persist- 
ently digest a larger proportion than 
the other. Often very greedy eaters 
show very poor fattening qualities. In 
young animals the digestive power is 
apparently equal to animals of mature 
age.
