It may be well at this point to compare the feeding stuffs on hand 

 and that may be purchased as to their content of digestible nutrients 

 and the cost of one pound of nutrients in each, at the prices assumed. 

 Be it remembered, however, that this comparison is made with the 

 prices assumed and that the cost of one pound of digestible nutrients 

 here given is true alone when the prices of the different feeding materials 

 are the same as those assumed. The method of determining the cost 

 per pound of digestible nutrients in these feeding stuffs is simple. 



Let us take oats as an instance. By reference to table 1 we see 

 that in one pound of oats there is .091 pounds of digestible protein, 

 .447 pounds of digestible carbohydrates and .041 pounds of digestible 

 fat. Adding together these amounts of protein, carbohydrates and fat, 

 there is as a result .570 pounds of digestible nutrients in a pound of 

 oats. Multiplying these amounts by 100 and setting them down in 

 tabular form we have this table: 



The cost of one pound of digestible nutrients given in the last column 

 of the table is found by dividing the value of the hundred pounds of 

 oats, at the price assumed, $.6875, by 57.9. 



In the same way the digestible nutrients and cost of one pound of 

 digestible nutrients were calculated for bran. 



Treating the other feeding stuffs in the same way we determine the 

 cost of one pound of digestible nutrients in each.

Comparing first the coarse fodders we note that digestible nutrients 

 cost over a cent and three quarters in timothy hay and but seven tenths 

 of a cent per pound in clover hay. A reference to Table I shows farther
