cent, and the oats 90.78 per cent, of drv matter, so that 3.84 

 pounds of dry matter in corn meal were fed against 4.05 pounds 

 in oats. In case of the third experiment 3.8 pounds of dry 

 matter in corn were fed against 4.02 pounds of dry matter in 

 oats. This matter was overlooked at the time, but should have 

 been guarded against by feeding slightly more corn meal. The 

 difference, however, while in favor of the oats was not so great 

 as to have caused a marked eifect upon the yields of milk, and 

 would be more than offset by the variations in the hay con- 

 sumed by the several animals as indicated in the above tables. 



Dry and Digestible Matter in Daily Rations (Pounds). 



Experiment I. 



The total dry matter fed in the first experiment was practi- 

 cally identical for each ration. In the second experiment the 

 cows averaged .55 pound more dry matter per day on the corn 

 meal ration. This was due to the fact that cows Minnie and Sa- 

 mantha ate more hay while receiving the corn meal. In the 

 third experiment the amounts of total dry matter consumed were 

 about the same. The average amount of digestible organic mat- 

 ter received by each cow was from about .6 to 1 pound less per 

 day on the oat ration, due generally to the less digestible matter 

 in the oats, and in ease of the second experiment to the less hay 

 eaten bv the two cows mentioned.
