 originally required to produce it. 



4*)1. The amount of food that an animal can 

 use profitably over and above that iXMiuin-d for 

 maintenance, depends upon the capacity (»f the 

 animal and the j)urpose of i)roduction. Morst 

 animals will make a return approximately in 

 proportion to the food consumed, up to a cer- 

 tain amount. Above that amount, the foo«l 

 simply passes through the animal ; or the di- 

 gestive ai)paratus becomes disordered and the 

 animal refuses to eat. However, the capacity
