FIFTY-FIRST ANNUAL CONVENTION 137 



Applied to Farms. 



This Milk Per Acre Demonstration, which is the theme 

 of this series of articles, was in no sense a model dairy farm. 

 In order to bring out distinct and conclusive evidence upon 

 the main objects, it was necessary to follow some plans that 

 would not apply in dairy farming. The farmer would be 

 free from certain limitations and disadvantages that could 

 not be avoided in this demonstration. The value is in the 

 foundation factors or principles of dairying proven out 

 through this six years of practical experience and high 

 results. 



Only twenty acres were available to raise the feed for 

 the demonstration, but that particular size of area has noth- 

 ing to do with the application of the results obtained to the 

 farm. The farmer may use whatever size of farm he has or 

 whatever part of his farm he wishes to devote to cows and 

 raising their feed. There is no ,necessity at all for the dairy- 

 man — as there was in the demonstration — ^to produce every 

 bit of the feed on any certain number of acres set apart for 

 dairying, but there is high reason for him to produce it 

 himself. 



Advantages on the Dairy Farm. 



The main feeds are to be the same — corn and alfalfa — 

 because they are the greatest yielding companion crops 

 containing suitable food elements. Sweet clover pasture 

 should be substituted for these as much as possible for the 

 summer months. The faimer will grow small grain to feed 

 the cows when producing heavily and have the straw left 

 for bedding and possibly wheat to sell as a cash crop. His 

 corn need not be grown Continuously on the same land but 

 can be rotated with small grain and sweet clover or soy 

 beans according to approved methods of crop rotation; and 

 much more corn may be grown than will be needed for the 

 cows which, of course, may be sold or fed to other stock. 



Scarcely ever would there be need for him to feed no 

 grain, as there was one year in this test, because he would 

 have the corn in excess of what went into the silo. He 

 would not need to grow corn continuously on one field and
