FARM DAIRYING 



products, to get accurate tests, double-necked test 

 bottles should be used. 



The amount is taken in a 17.6 c.c. pipette and 

 tested in the usual way. 



The milk has to be delivered slowly into the 

 larger neck or it bubbles out. 



The scale on the neck reads to one-hundredth 

 of one per cent. One large division reads five- 

 hundredths, or .05 per cent fat. 



COMPOSITE SAMPLES ; TESTING A HERD 



It is not always convenient, nor is it necessary, 

 to test daily when a yearly record is being kept of 

 a herd, or when milk or cream is delivered at a 

 factory. 



We will suppose a herd test is to be kept. There 

 should be a pint bottle with a long tight fitting cork, 

 for each cow. The cow's name or number should 

 be plainly written on a label which is gummed well 

 on the bottle, then given two coats of shellac so as 

 not to have the label come off when the bottle is 

 washed. 



The bottles should be placed on a convenient 

 shelf in the milk-room separated from the stable. 

 Hanging near should be a pair of spring scales set 

 to record the net weight of milk. (The milk pails 

 should be all the same weight.)
