protein. There will be a shrinkage either in milk or 

 body weight if the ratio of protein to carbohydrates 

 and fats is greater than that prescribed above. More- 

 over, feeds high in protein are expensive. 



To make this even more clear, nutritive ratio is 

 something obtained by dividing the sum of the digest- 

 ible carbohydrates and fats by the digestible proteins. 



To bring this point closer home, we will point out 

 the fact that there are two pounds of carbohydrates 

 to one pound of protein in separator skimmed milk. 

 That is, there is twice as much of carbohydrates and 

 fats as there is of protein. Therefore, the nutritive 

 ratio is expressed this way skimmed milk 1 : 2. 



In order that you may know exactly the nutritive 

 ratios of each one of the fodders usually fed to your 

 cows, we are printing herewith a table that is official : 



Nutritive Ratio 



Corn Fodder 1 : 14.9 



Mixed Grass and Clover 1 : 7.4 



Wheat Bran 1 : 3.7 



Skimmed Milk 1 : 2 



Corn Silage 1: 14.3 



Gluten Meal 1 : 2.5 



Corn or Cornmeal 1 : 9.7 



Mangles 1: 5.1 



Red Clover Hay 1 : 3.1 



Alfalfa (green) 1: 3.1 



Alfalfa (hay) 1 : 3.8 



So that you will not be confused we will state here 

 that the figures given above vary slightly from those 

 published by other experimental and agricultural uni- 

 versities. However, it agrees substantially with all 

 those published by the best authorities.
