THE FARM DAIRY 



1. The milk scale nas two indica- 

 tors. One rests at zero when there 

 is nothing on the scale. The other 

 is to be set at zero when the empty 

 pail is on the scale. This one re- 

 cords the weight of the milk directly. 



2. Let the pail hang on the scale 

 while recording the weight of the 

 milk. 



3. If there is not time to weigh the 

 milk every day, weigh it for three 

 successive days in the month or at 

 intervals as the 5th, 15th and 25th, 

 then to find the average production of 

 each cow, divide the total amount of 

 milk recorded from each cow by the 

 number of days the milk is weighed. 

 Multiply the result by the number of 

 days in the month which will give 

 approximately the total production 

 for the month. 



Taking the Sample. 



i. The best time to take the sam- 

 ple to test is immediately after weigh- 

 ing the milk. 



2. Always mix the milk well be- 

 fore taking the sample to thorough- 

 ly distribute the cream. 



3. The best sample bottles are 

 closed air tight to prevent evapora- 

 tion which increases the test. Label 

 each bottle with the name or number 

 of the cows so the samples will not 

 get mixed. 



4. If a sample from a single milk- 

 ing is to be tested take half a pint. 

 Where a composite sample is made 

 from several milkings retain about 

 two tablespoonfuls each time. 



5. A composite sample is made up 

 by taking two tablespoonfuls from 

 several milkings and keeping until 

 ready to test. 



6. If the sample Is held for a 

 time, in warm weather, use a pre- 

 servative tablet to keep the milk from 

 souring. These tablets are poisonous 

 and need to be handled with care.
