THIRTEENTH ANNUAL YEAR BOOK— PART X 533 



the work in a much more satisfactory manner than ever before. The 

 appointment of inspectors for the purpose of doing both dairy and food 

 work was something of a departure from former custom, and the re- 

 sults have been most satisfactory. 



EDUCATIONAL WORK. 



The records show that speakers from this department have addressed 

 over three hundred meetings within the last year. We have assisted 

 the Iowa State Dairy Association by furnishing men as speakers on 

 dairy trains. Many of the addresses have been before farmers' institutes, 

 dairy picnics, pure food shows, women's clubs, etc. 



INCREASE IN NUMBER OP CREAMERIES. "* 



We have assisted in the organization of a number of new creameries 

 as well as to. help those that have needed assistance of various kinds. 

 Our last report shows that Iowa had 494 creameries. This report shows 

 an increase of 18 or a total of 512. We think this a very creditable 

 showing. No branch of Iowa's manufacturing industries has more to 

 do with the general prosperity of our people than this. 



IOWA AS A BUTTER STATE. 



V/e have tried to present for consideration of the Iowa dairymen a 

 few concrete facts like the following: 



Iowa produces annually 100,000,000 pounds of creamery butter, Avhich 

 at 30 cents per pound is worth $30,000,000.00. 



The average Iowa cow produces 140 pounds of butter fat annually. 

 AlH increase of fifty pounds per cow would mean an additional income 

 to Iowa of $18,750,000. An increase of 100 pounds per cow would mean 

 a net increase of $37,500,000. 



The best Iowa county produces 7,542 pounds of creamery butter per 

 square mile. If the entire state produced an equal amount on each 

 square mile, Iowa would yield annually 418,558,875 pounds of butter 

 worth $125,567,622.50 or more than four times its present output. 



Herein lies Iowa's opportunity. 



Is it not worth while? 



We have tried to show that by the use of the scales and Babcock test 

 and the weeding out process with a little better care and feed they could 

 easily increase the production of their herd fifty pounds per cow per 

 year. That by the use of a pure bred dairy sire they could breed up 

 their herds and make a still further increase of fifty pounds per cow, 

 making a net increased income of $37,500,000.00. It is in the last three 

 or four years only that any considerable number of dairy sires have 

 been shipped into the state. It is easy to understand that it takes sev- 

 eral years before an increase in our production will be shown as most 

 of the heifers, the result of the first cross, would not be bred to freshen 

 before they are about three years of age. We maintain that a herd 

 bred up by the use of a pure bred dairy sire is for all practical pur- 

 poses, so far as the production of dairy products is concerned, as good
