42 DAIRYING. 



111. The New Jersey Experiment Station 7 years' record of a 

 herd of about 40 cows with an average production of 6,500 pounds 

 of milk, cost of feed per day 12.3 cents, makes the feed cost of 

 milk per quart 1.5 cents. 



112. The amount of feed that may be obtained for $35, which 

 has been assumed to be the average cost of feed per cow per year, 

 is very different in different sections of the country, as is showji 

 by the following figures reported as the feed consumed by one cow at 

 the Nebraska and at the "Wisconsin Agricultural Experiment 

 Station :

This shows the variation in prices of feeds in different sections 



of the country, and the. need of determining the facts on each farm 

 rather than measuring one's herd by the standard of some other 

 locality. 



F Cost of Equipment for Testing Cows by the Babcock Test. 



113. Several types of Babcock milk testers have been designed 

 by various manufacturers of these machines, but the process of test- 

 ing milk is the same in all of them. The hand tester is most com-
