A STUDY OF RATIONS FED TO MILCH COWS. 35 
once a day from a trough in the yard. ‘The grains fed in the 
test were Buffalo gluten feed and corn and cob meal. In the 
second test Chicago gluten meal was substituted for the Buffalo 
gluten feed. In each case the grains were fed independently, 
and not in a mixture as in several of the rations. With the 
exception of two cows which refused to eat the Chicago gluten 
meal in the second test, and which for that reason are omitted 
in the tables, there were no considerable irregularities to inter- 
fere with the results of the test. 
DISCUSSION OF THE EXPERIMENTS OF THE WINTER OF 
1896-97. 
The cost of the feeding stuffs, the pecuniary results of the 
experiments, the rations fed, and the physiological effects 
resulting from their use are briefly discussed in the following 
pages. 
The figures used for estimating the values of the feeding 
stuffs, z. ¢., the market prices per ton and the values of manure 
obtainable from one ton of each of the feeding stuffs are stated 
-in the accompanying table:
