FEEDING EXPERIMENTS WITH IIIILCH COWS, 



November, 1891 to March, 1892. 



DENT CORN vs. SWEET CORN. 



CORN MEAL vs. MAIZE FEED (Chicago Var). 



The experiments here under discussion were planned for the pur- 

 pose of comparing the food-value of a reputed variety of " Dent 

 Corn" with that of a standard variety of " Sweet Corn," when used 

 as the principal coarse fodder constituent in the daily diet of milch 

 cows, either in the form of "ensilage" or, in a more advanced state 

 of growth, in that of " stover." '• Pride of the North " was selected 

 as the representative of dent corns and " Stowell's Evergreen " as 

 that of sweet corns ; both kinds of corn were used in all cases in 

 corresponding stages of growth. 



The exceptionally high market price of the corn meal at the beginning 

 of our experiment, $31 per ton of 2000 lbs., rendered its substitution 

 in the daily diet of milch cows desirable for economical reasons. The 

 Chicago variety of "maize feed" was chosen for that purpose. This 

 comparatively new feed-stuff is one of the waste products of corn 

 obtained in connection with the manufacture of glucose sugar. The
