2 FEEDS AND FEEDING, ABRIDGED 



of the crops to animals and earing properly for the resulting manure, 

 most of the fertility may be retained on the farm, and the need of 

 commercial fertilizers long delayed. "Where intensive stock farming 

 is -followed and milling by-products rich in fertilizing constituents 

 are purchased and fed on the farm, the land may grow richer each 

 year, with little need for commercial fertilizers. 



Consumption of feed otherwise wasted. — In exclusive grain farm- 

 ing, there is no successful way of utilizing such materials as straw and 

 corn stover, and, being regarded as waste, they are often burned

In grain farming, the corn stalks are allowed to waste away in the fields after 

 the ears are harvested, but in live-stock farming the corn stover is profitably fed 

 to the stock. 



or otherwise disposed of without regard to the fertility lost to the soil. 

 In stock husbandry, all these by-products may be economically used 

 for feed or bedding. By this means much forage which cannot be 

 eaten by humans and would otherwise be wasted, is refined thru the 

 agency of animals into forms suitable for man, while most of the 

 fertility goes back in the manure to nourish the fields. Immense 

 quantities of by-products result from the manufacture of flour, break- 

 fast foods, vegetable oils, etc. Tho these are all unsuited for human 

 food, they are valuable feeds for stock. As our population increases,
