218 ILLINOIS STATE DAIRYMEN'S ASSOCIAITON. 



Me. Graham: I used to set my milk in those deep 

 setters, and when, for some cause or other, the oows 

 were not doing as well as usual, the amount of cream 

 measured on the can, indicated less than when they 

 were doing well. 



Mr. Lloyd: When my grade Jersey gives only a 

 little milk it is mighty thin compared with other 

 times. 



Mr. Hostetter : I think you can't tell by the looks 

 of the milk how much butter fat there is in it ; unless 

 you have tested it by the Babcock tester, you don't 

 know. 



Mr. Sawyer: I have noticed in testing that as a 

 rule cows under excitement will give a less percentage 

 of butter fat. There are cases on record, however, 

 where cows under excitement will give much richer 

 milk. The individuality of the cow has got to decide 

 that question. 



The president resumed the chair. 



Mr. Vail: When the milk ran up so high in the 

 percentage of butter fat, wasn't there a corresponding 

 decrease in the amount of milk? 



Prof. Farrington: That is what I look for, of 

 course, and that has been so generally in cows, but you 

 see by this record there was not a corresponding 

 decrease. 



Mr. MacMillan: In regard to the composite test, 

 is there a point beyond which it is not safe to keep the 

 milk, in other words, could we not make the test once 

 a month as well as every week. 



Prof. Farrington : I do not doubt but what that 

 would be possible; I don't know of its ever having 

 been tried. 



The Chairman : I have tried it between three and 

 four weeks, and it made a very clean, nice test.
