Why should the separator system be used in preference to 

 any other for securing the cream ? 



The first great advantage claimed for the centrifugal process 

 is the increased yield of butter secured. Careful experiments 

 have been made, more particularly in Sweden, Denmark and 

 Germany, with regard to this point, which prove that an in- 

 creased yield of from ten to twenty-five per cent is realized over 

 any other process. To creamerymen who are handling from 5,000 

 to 25,000 pounds of milk per day, this means the difference be- 

 tween profit and loss in the conducting of their factories. In 

 addition to this gain in quantity the superior quality has come to 

 be acknowledged in the best markets of the country, and to-day 

 your secretary read a list of premiums awarded to butter on 

 exhibition at this meeting, and the first premium for . best butter 

 made in the state of Illinois, at a whole milk creamery, was 

 awarded to butter made from cream separated by one of Dr. De 

 Laval's separators. As a further proof of the superior long- 

 keeping qualities of butter made by this process, I would say 

 that the first premium for June made butter was awarded at the 

 Fat Stock Show at Chicago to J. Colvin, of Kingston, 111., a 

 user of separators. Also nearly all the fancy butter that brings 

 the fancy prices of 75 cents to $1.00 per pound is made from 

 separated cream. 



Again, in regard to the value of the skim milk from the sep- 

 arator for feeding purposes, as compared with the stale, sour 

 milk of the setting system, we have the authority of Miller & 

 Sibley, one, if not the largest of the firms of breeders of Jersey 

 cattle in this country, to sustain us in saying that the fresh, sweet 

 milk from the separator is worth fifty per cent, of the whole milk 

 for raising calves. Not that it contains fifty per cent of the nutri- 

 ment of whole milk, but that with a slight addition of nitrogen- 

 ous matter in the shape of oatmeal and bran, it furnishes a per- 

 fect ration for the growing calf. Prof. Henry, of the Wisconsin 

 experimental station, also adds his testimony as to the value of 

 sweet skim milk for feeding hogs. In one of his bulletins he 

 says that in no case has he found it worth less than twenty-five
