period three was richer in albuminoids than in either other 
periods. 
With Jem and Meg the milk yield was brought from its lowest 
to the highest yield per day under the feed with corn meal, although 
the albuminoids consumed was much lower than in either of the 
following periods. With Ceres and Juno the largest flow of milk 
was under corn meal feed. In the following periods, although 
furnished a much larger amount of albuminoids, which was accom- 
panied also by a greater consumption of hay, yet the flow of milk 
fell off quite rapidly. This would indicate a greater value to 
corn meal as a milk producer than either linseed meal or wheat 
bran. | | 
Another point shown in these experiments is that the largest 
milk yield from the same cows does not necessarily give the greatest 
amount of butter, for in every case we secured the largest amount 
of butter with a smaller amount of milk produced by linseed meal 
feeding. 
Dors Foop INFLUENCE THE COMPOSITION OF BUTTER? 
For the study of this particular question— the influence of food 
on the butter—the winter’s feeding experiments were largely 
planned and carried out. It has been the general impression that 
the food did not influence the composition of the butter fats, but 
rather that the composition of the fats was individual and breed 
characteristics inherent in the animal. The most of the German 
experiments, as well as those conducted in this country, have 
tended to show this to be the case, although in a few instances 
results have been obtained which would indicate that such was 
* not always the case. 
My studies, upon the composition of our feeding stuffs, especially 
of the albuminoids and oils, have led me to think that, at least in 
_ some instances, the peculiar properties of the food did affect the 
composition of the butter and animal products produced from them. 
I selected three grain feeds, corn meal, linseed meal and wheat 
bran, to be used in connection with hay feed to learn what differ- 
ence, if any, could be detected in the butter. 
The conditions of feeding and experiment have already been 
given, and need not be repeated, and the results of the trials have 
been given in the tabular form in the preceding pages. The tests
