SANITARY MILK PRODUCTION 



189 



States show the greatest range in prices, 1.363 cts., the December price 

 being 4.204 cts. and the June price 2.841. 



The late G. M. Whitaker investigated the extra cost of producing 

 clean milk and found that to increase the dairy score from 42 points which 

 he believed should be attained as a natural and necessary incident of 

 milk production, to approximately 70 points, which he held practically 

 met modern sanitary requirements, the following added expenses would 

 be incurred in a 15-cow dairy.

 extreme cases, 5^ cts. for new or additional equipment; and if we add 5 cts. more 

 to remunerate the proprietor for his extra care and vigilance there will be an 

 extreme increase of 15}^ cts. per cow per day. The product of a cow ranges 

 from 4,000 to 10,000 Ib. of milk a year, or from 5 to 12 qt. a day. The added 

 expense for labor would therefore amount to about % to 1 ct. a quart, and in 

 rare instances where great additional expense is required for repairs, new con- 

 struction, and new equipment, this might raise the increase 1 to 2 cts. a quart 

 more. The allowance for extra remuneration to the dairyman for added care
