ANIMAL FEEDING. 51 



DIGESTIBLE NUTRIENTS IN SOME COMMON FEEDING STUFFS. 



Process: For a trial ration suppose we decide to take 10 

 pounds of corn stover, 10 pounds of cowpea hay, 5 pounds of 

 clover hay. The digestible nutrients in these are ascertained as 

 follows : 



Corn stover is 



59.5 per cent dry matter, 



1.7 per cent digestible protein, 

 32.4 per cent digestible carbohydrates, 



0.7 per cent digestible fat. 



Therefore in 10 pounds there will be, approximately : 

 Dry matter, .595 X 10 = 6.0 pounds, 



Protein, .017 X 10 = 0.2 pounds, 



Carbohydrates, .324 X 10 3.2 pounds, 



Fat, .007 X 10 = 0.1 pounds. 



The digestible nutrients of cowpea hay are ascertained in the 

 same way : 



Cowpea hay 10 pounds. 

 Dry matter, 

 Protein, 

 Carbohydrates, 

 Fat, 



.893 X 10 = 3.9 pounds, 

 .108 X 10 = 1.1 pounds, 

 .386 X 10 = 3.9 pounds, 

 .011 X 10 = 0.1 pounds. 



Clover hay 5 pounds. 



Dry matter, .847 X 



Protein, .068 X 



Carbohydrates, .358 X 



Fat, .017 X 



5 = 4.2 pounds, 

 5 = 0.3 pounds, 

 5 = 1.8 pounds, 

 5 = 0.1 pounds. 



Arranging these for comparison with the feeding stand- 

 ard, to see whether the proportions and quantities of
