10. Milk-testing associations—In some places local 
groups of dairymen organize as a body and enter their 
herds for testing both the butter fat and quantity of milk. 
Both morning and night milkings are weighed and set 
down on record sheets. Once a month samples are taken 
to test for butter fat. Such associations are most success- 
ful when enough herds are under test that a trained milk 
tester may go from herd to herd obtaining samples of all 
the individual cows and determining the full measure of 
production. The usual cost for making such tests is from 
$1 to $2 per cow a year. Cow testing associations point 
out the good and poor cows of a community. By elim- 
inating the poor cows and preserving the heifer calves 
of the best cows for milkers, 
aherd can soon be improved. 
11. Advanced register.— 
All of the important dairy 
cattle clubs now maintain 
an advanced registry, in 
which are recorded tested 
cows that meet certain re- 
quirements as to production 
of butter fat and total milk 
yield. Prescribed regula- 
tions are enforced as to 
when a cow may be entered 
and under what conditions 
the tests areto be made. The 
dairy breed associations co- 
operate with the experiment
