Conclusions. — The results of the past season obtained in 

 this connection are very encouraging, as will be seen from 

 the subsequent brief abstract when compared with those 

 noticed in preceding years. 



1 . The yield of milk is well maintained during the entire 

 experiment of three months. The average daily yield of 

 milk of the various cows for the entire experiment is in four 

 out of five cases larger than their yield at the beginning of 

 the observation ; in the fifth case there is practically no 

 change (Cora). The largest average yield of milk was 

 noticed, without any exception as to a particular cow, in 

 case of soja bean as green fodder and dried brewers' grain 

 as ingredient of the daily grain feed ration (fourth feeding 

 period) . Green fodder corn leads in three out of five cases 

 the green vetch and oats when fed with dried brewers' grain. 



2. The amount of dry vegetable matter consumed per 

 quart of milk produced varies in case of different cows from 

 1.77 pounds (Cora) to 3.33 pounds (Pearl). The amount 

 consumed in case of the same cows varies in different feed- 

 ing periods from 1.77 to 2.25 pounds (Cora) and from 2.44 

 to 3.17 pounds (Buttercup). 



3. The total cost of feed consumed per quart of milk 

 produced differs in case of different animals for the same 

 feeding period from 1.69 to 2.30 cents (Lucy and Pearl, 

 fifth feeding period) ; as far as different feeding periods are 

 concerned it varies in one case from 1.69 to 2.30 cents 

 (Lucy) and in another case from 2.24 to 2.91 cents (Clarissa) . 



4. The net cost of feed per quart of milk produced varies 

 from 1.01 to 1.43 cents for the same feeding period in case 

 of different animals (Lucy and Pearl, second feeding period) . 



5. The obtainable manurial value amounts on an average 

 to three-sevenths of the market cost of the feed consumed. 

 The green vetch and oats leads in this connection. 



6. The quality of the milk is in every instance improved 

 in the percentage of solids during the experiment without 

 showing any perceptible decrease in yield. Individuality 

 of the animal and stage of lactation affect the results to a 

 controlling extent. 



7. Brewers' grain has served as an excellent substitute 

 for wheat bran in our diet for milch cows.
