54 AGRICULTURAL EXPERIMENT STATION. [Jan. 



Summary of Experiments. 



[Based on the same cost of feed and manurial valuation of feed consumed.] 



From the above summary it is apparent that the course of 

 feeding adopted in the seventh experiment has given the 

 most satisfactory pecuniary results ; for the net cost of feed 

 consumed amounted to 3.39 cents per pound of dressed pork 

 produced, after allowing a loss of thirty per cent, of the 

 manurial value of the feed, in consequence of the growth of 

 the animal. As we sold our dressed pork for from 5| to 7^ 

 cents per pound, we received from 1.5 to 3.5 cents for labor, 

 housing, etc. 



The statement that an addition of gluten meal or of wheat 

 bran or of both, to a diet which previously consisted only of 

 skim milk and corn meal, tends to increase the commercial 

 value of the manurial refuse resulting, is based on the follow- 

 ing considerations : — 



First, The principal fertilizing elements contained in a 

 mixture of equal parts of gluten meal and w'heat bran have 

 a higher market value than those contained in an equal weight 

 of corn meal. 



Second. It is admissible, for mere practical purposes, to 

 assume that, in raising one and the same kind of animals to 

 a corresponding weight, a corresponding amount of nitrogen, 

 of phosphoric acid, of potash, etc., will be retained and stored 

 up in the growing animal. 



An excess, therefore, of any or of all of the three essential 

 fertilizing constituents previously specified, in one diet, as 

 compared with that of another one, counts in favor of that
