same commercial feed stuff affects the cost of the uitrogen-contain- 

 ing food constituent, in particular as its supply is more limited than 

 that of the non-nitrogenous food constituents, which our home-raised 

 coarse fodder articles contain, as a rule, in abundance and which 

 therefore needs not to be secured from outside resources for cash. 



The subsequent tabular statement assumes a constant cost of 

 digestible non-nitrogenous food constituents, — sugar, starch, fat, 

 etc., — and shows thereby the variations in the cost of digestible 

 nitrogen-containing food constituents in case of some prominent con- 

 centrated commercial leed stuffs in our local market. 



The majority of analyses stated is made of fodder articles which 

 have been used either during the past year in co;inection with some 

 of our feeding experiments, or have been rais-^d upon the grounds of 

 the station. Some articles sent on by outside parties are added, on 

 account ot the special interest they may present to others. 



Valuation of Fodder- Articles on the following Basis. 



Digestible cellulose and nitrogen free extract matter, 1.00 cent, per pound ; 

 digestible fat, 2.50 cents per pound. The value of digestible protein deter- 

 mined the difference of the sum of both and the market cost of the fodder 

 articles. (Calculation is based on dry matter, 2,000 pounds.)
