0 Averages obtained by dividing the total weight of fat or solids by the total weight of milk. 
Table XXIV shows that the corn-meal ration produced an increase of 
528 pounds of milk, or approximately 8 per cent over that produced by 
the ivory-meal ration. The total solids were also increased 73.62 pounds 
and the milk fat 21.89 pounds. The cows in this experiment were in an 
earlier stage of lactation than those used in the previous trials, and the 
results are to be regarded as the most satisfactory. It is evident that 
while the vegetable-ivory meal possesses a distinct feeding value, a given 
amount has not the feeding equivalent of the same amount of corn meal. 
The methods of experimentation with milch cows are not sufficiently 
sharp to enable one to draw accurate deductions as to the exact relative 
feeding effect of the two materials.
