48 VERMONT DAIRYMEN'S REPORT. 



must, for greatest profit, be superseded by the centrifugal separa- 

 tor, — the eight quart can by the sealed glass bottle. Whatever 

 class of dairying New England is engaged in, it is the part of 

 wisdom to adopt such apparatus as will lessen waste and improve 

 quality. It is not my wish to recommend this or that piece of 

 apparatus, but in general to urge the wider use of modern 

 machines for dairy purposes. 



(b) Economy in crude slock, i. e., home grown and pur- 

 chased feeds. This, as Rudyard Kipling says, "is another story." 

 The discussion of economical dairy feeding in all its phases 

 would take far more time than can be given to it here. 



In the brief time which can be allotted to this section of 

 the general subject, I can hardly do more than allude to the 

 salient points. Without attempting to go into the matter of 

 the science of stock feeding, let me call attention to what 

 appear to me to be the more economical roughages and con- 

 centrates, and what are probably uneconomical at ruling 

 prices. 



I want you to remember, as I have done, a remark of 

 Director Jordan, of the New York station, made in his address 

 to this Association last year. His epigrammatical statement 

 struck me as very apt and seems worthy of emphasis and 

 reiteration. I believe that it strikes the keynote of the success- 

 ful dairy practice of to day in this latitude in so far as it per- 

 tains to feeding. He said that the "proper function of the 

 farm in dairy feeding is that of a carbohydrate factory and the 

 proper function of the market was that of a protein supply." 



What did he mean by this statement ? He meant, I think, 

 three things : 



(a.) That carbohydrates were grown upon the farm with 

 relative ease, but that it was difficult and usually impossible to 

 grow enough protein upon the farm to provide a large number 

 of dairy cows with a balanced ration. 



(b.) That since the by-products of several industries are 

 notably rich in protein and are sold at fairly reasonable prices, 

 it was often cheaper to buy this material than to raise it. 



(c.) That while the farm-growing of protein was to be en- 

 couraged, yet it was usually in the line of economy to grow 

 carbohydrates in as large amounts as possible, and to buy pro- 

 tein in order to supplement this growth, thus properly balanc- 

 ing the ration, provided the cows to which the ration was to be 

 fed were of the proper grade. 



In my judgment the more common roughages and concen- 

 trates may be classified as economical and uneconomical, as 

 follows :
