 likely costs him more effort to extract the digestible 

 matter therefrom than the energy this can supply. An 

 animal lives on and produces not from what he eats but 

 from what he digests. 



Relative value of feeding stuffs. Since the price of 

 different feeding stuffs varies greatly with the locality 

 and season, it is impossible to give definite statements 

 as to the relative economy which will hold good always; 

 it may be said, in general, that the feeding stuffs richest 

 in protein are our most costly and at the same time our 

 most valuable foods. Experience has shown to a cer- 

 tainty that a liberal supply of protein is an advantage 

 in feeding most classes of farm animals, so that if such 

 feeding stuffs can be obtained at fair prices, it will pay 

 to feed them quite extensively, and they must enter into 

 all food rations in fair quantities in order that the 

 animals may produce as much milk, meat, or other farm 

 products, as is necessary to render them profitable to 

 their owner. The following statement shows a classifica- 

 tion of feeding stuffs which may prove helpful in decid- 

 ing upon kinds and amounts of feeds to be purchased 

 or fed.
