CHAPTER XXI 



HOW PRACTICE SUPPORTS THEORY — A RECORD IN 

 CHEAP MILK PRODUCTION 



So much for theory, now for practice. The question 

 immediately arises in the mind of every practical 

 farmer: does the cow agree with the chemist? The 

 answer is a decided "Yes." 



In an experiment conducted by the writer in the 

 year 1913-14, two lots of cows were fed, one lot on 

 Ration 1 and the other on Ration 2. The results, 

 tested both by the milk produced and the butter fat 

 contents of the milk, demonstrated that Ration 2 was 

 equally as good as Ration 1. 



At the time that the experiment was carried out, 

 the cost of the food for the production of 1 gallon of 

 milk on the root, meal, cake ration, was 4fd., whilst 

 the cost of producing a gallon on the Continuous Crop- 

 ping ration was only a little more than half of this, 

 viz., 2|d. per gallon, the lowest cost on record at 

 which winter milk, so far, has been produced in these 

 countries. 



In the experiment the roots were charged at 10s. 

 per ton, winter greens at 3s. per ton, meal and decorti- 

 cated cotton cake at cost price, i.e., £6 10s., and £9 

 per ton, respectively, and meadow hay and vetch hay 

 at £2 per ton. These prices were, of course, pre-war 

 time prices. If we consider the comparative cost of 

 food for milk production at present-day prices, the
