The results are the same in each case. So far as this trial is con- 

 cerned the claim is refuted that Pratts Food produces a richer milk. 

 It is a well known fact that the richness of milk depends primarily 

 on the breed and individuality of the animal and also upon the stage 

 of lactation, and is not due to the infiuence of any particular food or 



medicine. 



Food Cost of Milk and Butter. {Cents). 



In making the above calculations Pratts Food was reckoned at 

 6 cents a pound and the other feed stuffs at regular market rates. 

 The increased cost of Pratts Food over ordinary grains increased the 

 cost of both milk and butter by fully 10 per cent. 



Dry and Digestible Matter Required to Produce Milk and Butte/ . 



The results are practically identical. Pratts Food gave results 

 similar to a like quantity of a mixture of corn meal and wheat 

 middlings. 



The experiment shows clearly : 



1. That Pratts Food did not substantially increase the quantity 

 of milk and milk ingredients over that produced by a like amount of 

 ordinary feed stuffs. 



2. That Pratts Food failed to increase the richness of the milk. 



3. That the cost of milk and butter was increased fully 10 per 

 cent when Pratts Food was fed. 



4. That no effect favorable or otherwise upon the general health 

 and condition of the animals was noted from the addition of Pratts 

 Food to the daily ration. 



Dairymen are at liberty to draw their own conclusions from 

 the above results.
