for protein, fat and nitrogen-free extract, respectively. Several 

 American Stations have also endeavored to ascertain the money 

 valne of concentrates according to the nutrients they contain, Tfith 

 the results presented in the table below: 



Valuations of nutrients in American concentrated feeding stuffs — 

 various Eopperiment Stations. 



The data in the above table were secured in the following 

 manner: The market values of all the concentrated feeding stuffs 

 in the state were tabulated, together with the pounds of digestible 

 protein, carbohydrates and ether extract they contained. Then 

 by a mathematical process the supposed relative value of each of 

 the nutrients was determined, with results presented in the table. 

 In Connecticut, for example, it was foimd that taking all the 

 common concentrated feeding stuffs offered in the market at cur- 

 rent values, each pound of protein in these feeds cost on the 

 average 1.6 cents, one pound of fat 4.2 cents, and a pound of car- 

 bohydrates .96 cents. Hills, Boyce and Jones, of the Vermont 

 Station,' calculating the commercial values of concentrates for 

 their state, found by the process usually employed that a pound 

 of fat had a value of— .19 cents, or that it was worth less than 

 nothing, — an absurdity of course. Surprised at this, they inves- 

 tigated the subject in a broad manner and came to the conclusion 

 that the method employed to determine these values is inaccurate 

 and without merit. At present it is impossible to state the value 

 of one feeding stuff in terms of another from calculations based 

 upon the nutrients contained in each.
