TESTING AND HANDLING OF MILK AND CREAM 
be supplied upon application, either by the State Dairy Commission or 
the Dairy Division of the U. S. Department of Agricuture, Washing¬ 
ton, D. C. 
The equipment needed for running tests for a small dairy herd, 
with the cost, is given below: 
One automatic milk scale (30-lbs. capacity). $3.50 
On 4-bottle Babcock tester, with necessary glassware for milk. 5.00 
One dairy thermometer.25 
Sulphuric acid. 
$8.75 
A large covered tester may be had without glassware equipment 
at prices ranging from the 6-bottle size at $9.00 to a 12-bottle size at 
$14.00. Where many tests are to be run at once, it is a saving of time 
to have the larger machine. 
If cream is to be tested, scales for weighing the tests are required, 
which cost from $4.50 to $12.00 for the one bottle size. Cream bottles 
will also be needed, which will cost $1.00 for four, or additional glass¬ 
ware needed for making cream tests may be included in the order for 
the 4-bottle Babcock tester for an added cost of 50 cents. 
Complete directions for running milk tests will be found on page 5. 
Approximate cream tests may be made by measuring the cream 
into cream test bottles by the use of a 9 c. c. or an 18 c. c. pipette 
instead of weighing. In this case the pipette should be rinsed out 
and the rinsings transferred to the test bottle, or the test will be too low. 
If cream is measured into the test bottles, care should be taken 
that the cream when measured is not in a foamy condition. Cream 
from the centrifugal separator should not be measuied into the test 
bottle immediately after separation as such cream contains considerable 
foam. It should be understood, however, that cream 
tests made by measure 
are only approximate and 
are not as accurate as 
the weight measure tests. 
This method is given only 
for testing on the farm 
where cream is not bought 
or sold upon tests made, 
and test scales are not at 
hand. Such a method will 
serve as a rough check 
upon creamery tests, and Babcock tester for a small herd 
then if sweet cream is sold for direct consumption, it is 
Milk scales desirable to know the proper richness of the cream.
