We see from the sum of these nutrients that about 1.7 pounds 

 more of protein, 5.5 pounds of carbohydrates and 0.1 pound of 

 fat -are needed, which can be most easily supplied with concen- 

 trated foods. Suppose we take 2 pounds each of corn meal, 

 cotton-seed meal, gluten meal and bran. Then the percentage 

 of nutrients of each given in the table should be multiplied by 2 

 which will give us a ration of the following composition: 



Southern corn silage, 35 lbs 

 Mixed hay, 10 " 



Corn meal, 2 



Cotton-seed meal, 2 " 



Gluten, 2 " 



Bran, 2 "
