VARIATION IN TESTS OF MILK. 167 



weight (some of the more beefy ones gaining considerable as is indicated by 

 the best gains). 



A tabulation of results of this test combining the production of butter- 

 fat and solids not fat has been made at what may be called farmers' prices, 

 that is, the net price of butter to the creamery patron plus feeding value of 

 skim milk. For the months during which the test was conducted (May 1 to 

 November 1) IGc. is taken as this value of butter, and by a sort of established 

 rule among experimenters and writers, 2c. per pound for solids not fat, or 

 about 18c. per 100 pounds of average skim milk. 



The following table shows the standing of the herds on this very prac- 

 tical basis:
