These are the quantities of digestible ingredients in 100 pounds 

 of the different feeding stuffs. A determination of what our ration 

 will furnish is now a simple matter. For instance 40 pounds of 

 ensilage contains four-tenths as much as 100 pounds, so we have : 



Organic matter 12.74X4-10 = 5.10 



Protein 1.09X4-10= .436 



Fats 51X4-10= .20 



Nitrogen-free extractive matter 6.87X4-10 = 2.75 



Crude fiber 4.09X4-10=1.64 



A similar calculation for the ha}', meal and bran gives the follow- 

 ing figures : 



Digestible Material in Proposed Ration. 



A comparison shows this ration to be wideh' difTerent from the 

 German standard. 



Proposed r«tioD. Germaa ration. 



Organic matter (total nutrients) .. .. 14.45 15.40 



Protein 1.32 2 5 



Nitrogen-free extract and fiber 12.59 12 5 



Fats .52 40 



Nutritive ratio. 1:10 3 1:5.4 



The proposed ration differs from the German standard mainly in 

 having a much less quantity of digestible protein, the total digestible 

 material being somewhat less also. 



While it is doubtful if feeding 2.5 pounds of protein, would be 

 good economy, but little over half that amount is undoubtedly too 

 small a quantity- to secure the most profitable results. It is evident 

 that the thing to do is to feed for a portion of the grain ration some
