With the fat reduced to carbohydrates the ration reads :

 Standard ■ 



Nutritive 

 ratio 



1:4.2 

 1:5-4 



The ration is too high in dry matter, digestible protein and 

 digestible carbohydrates. The ration is also too narrow. 



Improviiig, the Ration. — Let us try to improve this ration by 

 supplying less of the nutrients and particularly less protein. By 

 consulting Table I we learn that cotton-seed meal has more di- 

 gestible protein than any of the other feeds in this ration. Sup- 

 pose then we reduce the amount of cotton-seed meal to 3 lbs. 

 Then the ration will be as follows:
