Nutritive Ratio. 



Conclusions deducted from the Results obtained. 



1. The amount of dry organic matter contained in the 

 feed consumed per pound of dressed pork secured varies in 

 case of different animals from 3.80 to 3.99 pounds, the 

 mean being 3.87 pounds. 



2. The total cost of the feed consumed for the production 

 of one pound of dressed pork secured varies in case of 

 different animals from 5.43 to 5.72 cents, with a mean of 

 5.55 cents. 



3. The total cost of the entire feed consumed during our 

 late experiment XI. amounts to $39. The total market value 

 of the entire amount of the essential fertilizing constituents 

 contained in the feed consumed amounts at current market 

 prices to $19.92. In making the customary liberal allow- 

 ance of 30 per cent, for the loss sustained in nitrogen, 

 phosphoric acid and potassium oxide, in consequence of the 

 formation of flesh and bone in the growing animals, it will 

 be noticed that the obtainable manurial value of the feed 

 consumed amounts still to $13.94, which sum is fairly equal 

 to one-third of the original cost of the entire feed used, or 

 1.98 cents per pound of dressed pork produced (702.75 

 pounds). 



4. As the first cost of the feed consumed for the pro- 

 duction of one pound of dressed pork amounted on an
