THIRTY-FIFTH ANNUAL CONVENTION. 133 



0. — What variance between the cream test and milk test? 

 Where a patron tests his milk from each individual cow separate- 

 ly, weighing and sampling each milking, what difference ought 

 there to be if any between the amount of butter fat from the milk 

 and the amount the creamerymen figure? 



A. — There will be some variation. There is a little loss in 

 the skimmilk, and it has been my observation when I have done 

 the testing in the creamery and the University was doing herd 

 testing among the farmers, they will get a little less from the 

 creamery than when each cow's milk was weighed and tested 

 separately and the total butter fat figured that way. It will vary 

 in different cases. 



Q. — I find in some places that some months I get from 10 

 to 15 pounds more fat and sometimes less. How do you figure 

 that out? 



A. — Well someone surely made a mistake. Have you ever 

 tried to take a composite test of all your milk and compared it 

 with the creamery? 



Q. — A test morning and evening, one day out of a month 

 and weigh the milk every day. 



A. — You may pick the cow out on a day when she gives a 

 higher test than normal, and also the other way, and that to 

 some extent would account for the variation. I have found 

 that you as a rule will recover less from the cream after the milk 

 is separated. Just how much I can't say; it will depend upon 

 the thoroughness of separation and the care you take. 



Q. — About per cent on skimmilk, or rather what is close 

 skimming? 



A. — Anything below .05 of one per cent or one space on the 

 skimmilk bottle; that means one-half pound for 1,000 pounds 

 of milk. Most hand separators in good running order, when
