410 JOVVA DEPARTMENT OF AGRICULTURE. 



Mr. Wentworth : I would like to ask the gentleman this, 

 what the custom is in Wisconsin of testing. Do the patrons make 

 the tests themselves or do they take their samples and send them 

 to the creamery or cheese factory and have the operator make 

 the test? 



Mr. Gillette: The tests are taken by composite samples 

 from the milk that is delivered to the factory each morning, and 

 those composite samples are tested from once to twice a month 

 at the factory. 



Mr. Wentworth : I meant the individual cow or herd. 



Mr. Gillette: Not often. What we call our official tests 

 m Wisconsin are conducted entirely by representatives of our 

 experiment station and that matter is taken entirely out of the 

 hands of the owner of the animals. Does that answer your 

 c[uestion ? 



Mr. Wentworth : It does in part, but I do not think yoii 

 catch my idea. What I wanted to get at was this. — suppO'Se 

 that I am living in Wisconsin, or Iowa for thart matter, but 

 under Wisconsin conditions is what I desire to get. I weigh 

 my milk and take a sample. Now woukl I , or is it the custom 

 there for the farmer to have his individual test and make the 

 test himself, or do you send those samples to the factory and 

 have the buttermaker make the test O'f the individual cow? 



Mr. Gillette: It is done both ways. I regret to say that 

 like some of you people in Iowa and other states in regard to 

 this great dairy problem of weeding out and selection, that 

 much of this matter is neglected in Wisconsin and in every other 

 state; but our best dairymen weigh their milk usually from every 

 animal in the herd and take composite samples every two or 

 three days in the month, and that composite sample is used as 

 a check on that cow for that month; so with the weights of the 

 milk and per cent of butter fat arrived at in the test, which he 

 saves himself, and I might say that test is sometimes made by 

 the owner of the cow and at the factory, he is able to know at 

 the end of the year just where that cow stands.
