Taking the last half of each period, when the influence of the pre-

We note here that with increase of albuminoid fed, there appears in 
general an increase of milk yield and an increase in live weight, the 
exception being in periods one and five. In period one the albuminoid 
was mostly in the linseed meal; in period five, in the bran. The con- 
clusion must therefore be, that: First, increase of albuminoid fed 
within the limits of this trial, is favorable to increase of milk and live 
weight. Second, that the albuminoid of the linseed meal is more 
favorable to live weight than is the albuminoid in the bran. Third, 
that the albuminoid in the bran is more favorable for milk yield than 
is the albuminoid in the linseed meal. 
Expressed otherwise, so far as this one trial is concerned, linseed 
meal should be chosen as a leading portion of the ration where flesh 
is desired, and bran when milk is the object. 
We may note also from the tables that the mixture of foods increased 
the amount of food consumed, and thus had a favorable effect upon 
the yield. Thus, during period two, of hay feeding alone, but 13 . 8 
pounds of hay was daily eaten, while during period one, with linseed 
meal and pumpkins, 16 . 7 pounds of hay was utilized. During period 
five, with bran, 16 . 7 pounds of hay was consumed. We may hence 
infer that the mixture of foods was favorable in the inducing of a 
larger consumption, and that linseed meal and pumpkin, and wheat 
bran was of especial service, corn meal and bran less so, and corn
