The above analyses, representing as they do several animals, 

 and extending over a period of two years, furnish information on 

 several points that are worthy of consideration. 



(1.) The effect of breed upon the composition of milk. 



The quality of the milk as based upon the percentage of solid 

 matter in it, is best with the Jerseys and poorest with the Hol- 

 steins. If the milk solids of the Holstein milk are represented 

 by 100 we have as follows : 



Holstein, 100 ; Ayrshire, 106 ; Jersey, 125. 



It is to be observed that the relation in quantity of the various 

 constituents of the milk solids is not the same with all the breeds.
