THE DEVELOPMENT OF DAIRYING 205 



Sev mty-four per cent of the steers and bulls in the United 

 Stages are west of the Mississippi River, but only thirty 

 per cent of the population is in that region. 



The relative weight and bulk of the feed and of the human 

 foo< made from it, the perishability of the product, and the 

 cost of feed are the primary factors that determine where 

 different animal products shall be raised. When a liberal

use of corn silage and pasture is made, and if we include 

 the feed for the young stock as well as for the mature ani- 

 mals, a pound of butter represents approximately 100 pounds 

 of feed. A pound of cheese or dressed beef represents about 

 50 pounds of feed, and a pound of milk 5 pounds of feed. 



If drier feeds are used, the quantities will be less, but 

 approximately the same proportions will still hold. With 

 hay and grain a cow sometimes gives a pound of milk for 

 each pound of feed. A steer fed in a box stall for three 

 years used 38 pounds of feed for each pound of dressed beef. 1
