COST OF NUTRIENTS

PROTEIN IN CERTAIN FEEDING STUFFS 



A ton of corn contains 158 pounds of protein, 

 which is worth 65 cents a bushel, or $25 a ton. One 

 pound of protein will therefore cost 2,500 divided by 

 158, or 15.8-)- cents a pound. 



In like manner the cost of a pound of protein in 

 each feeding stuff is determined, giving us the fol- 

 lowing: 



Here we see that at the prices assumed cottonseed 

 meal and gluten meal are by far the cheapest sources 

 of protein. 



The same method is followed in determining the 

 protein value of every other foodstuff. So simple is 

 it, every feeder and stockman should make it a point 

 to determine always the feeding values of different 

 feeding stuffs in this comparative manner.
