THE DATA PRESENTED AS A FORMULA. 



The data in this bulletin are more or less a record or history of the 

 dairy business for the past three years and do not represent present 

 conditions, due to the change which has taken place in prices. For 

 this reason the following formula has been designed for the purpose of 

 making this data applicable to all conditions, and by applying current 

 prices to the amounts of feed and labor given, the portion of the cost 

 of milk represented by these factors should be approximately correct. 

 While this formula ouly gives the feed and labor items, the other items 

 which cannot be represented in terms of pounds or days are conse- 

 quently represented by a corrective factor, which means a factor stated 

 in percentages of feed and labor. For example, the corrective factor 

 for the winter feeding period is .2183 or 21.83% of the feed and labor 

 costs. This corrective factor has been adjusted so as to take care of 

 the receipts such as manure, etc., and the total gives the net cost of 

 producing 100 pounds of milk. If the feed and labor costs, including 

 the hauling of milk amount to $3.25, then $3.25 multiplied by .2183 

 equals $0.71. |3.25 plus |0.71 equals $3.96, the net cost of 100 pounds 

 of milk. The same application holds true for all the seasons and the 

 year. 



A FEED AND LABOR FORMULA. 



The following formula give the average feed and labor items and 

 their amounts, entering into the production of 100 pounds of milk at 

 \ Howell and Webberville for each season and the year. The other costs 

 (overhead) are determined by multiplying the value of these items by 

 the corrective factors given, thus giving the approximate net cost of 

 producing milk.
