THE DAIRY HERD RECORD 321 



Rule a sheet of paper as the accompanying milk record sheet 

 in " Student's Notes and Report " l is ruled. Tack the milk 

 record sheet on the wall in the barn, near the cows. Sus- 

 pend the pair of spring balance scales from the ceiling near 

 the milk sheet. Fasten a lead pencil to a spring and attach 

 it to the wall near the milk sheet. Keep a record of the 

 milk of each cow for one month. (To determine the value 

 of a cow for milk production, a complete record must be kept 

 of the milk produced from the time she freshens until she is 

 dry.) A test of each cow's milk for butter fat should be 

 made at the beginning and end of the month. To secure a 

 sample of the milk for testing, take a small quantity (about 

 three tablespoonfuls) of the milk of each cow from each 

 milking for two days. The milk should be thoroughly mixed 

 before sampling. Place the milk from each cow in a sepa- 

 rate bottle and label. Test each sample for butter fat by 

 means of the Babcock test (Ex. 52). 



Figure up the total amount of milk given by each cow 

 during the month. Determine the value of the milk sold 

 from each cow during the month. If whole milk is sold, figure 

 the value in pounds or gallons. A gallon of milk weighs 

 8.66 pounds. If cream is sold, figure the value of the butter 

 fat from each cow. Get the market price of whole milk and 

 the market price of butter fat in your community and figure 

 in which way it would be the most profitable to sell your 

 milk.

 from your State Agricultural College or Experiment Station.
