The Bulletin 7 



fair comparison, however, can be made of the milk and butter-fat pro- 

 duced. 



Profit or Loss. 



In this bulletin profit or loss refers to the difference between the total 

 value of the products and the total cost of the feed. JSTo charge for 

 feed, other than pasture and roughage, was made while the cows were 

 dry. No charge was made for labor; it was considered that the value 

 of manure and the calf would largely offset this item. However, this 

 will not always hold true in the case of a scrub herd where a poor sire 

 is used.
