DAIRYING. 41 



These figures show a difference of about 10,000 pounds of milk 

 and $38.00 worth of feed between the extreme cows or nearly $4.00 

 worth of feed for every 1,000 pounds of milk when the milk pro- 

 duction is above 4,500 pounds. If then, the cow giving this amount 

 of milk, (4,500 pounds), is worth a given sum, and milk is worth 

 $1.00 per 100 pounds, each increase of 1,000 pounds of milk adds 

 $6.00 to the value of the cow, as this represents the difference 

 between the $10.00 for the 1,000 pounds of milk and tjie $4.00 worth 

 of feed required to produce this milk. 



108. Fraser places the value of a cow producing 2,000 pounds of 

 milk and 80 pounds of butter fat at $30.00, and adds $5.00 to the 

 value of the cow for each increase of 1,000 pounds of milk up to 

 7,000 pounds. Where a cow produces 7,000 pounds of milk and 

 above he adds $10.00 for each 1,000 pounds of milk produced per 

 year.

 been variously estimated in different sections of the country. Wing
