206 FEEDING OF FARM STOCK. 



Using the figures in the above table, we can easily com- 

 pute the number of quarts in any given weight of feed or 

 mixture of feeds. 



For example, take the following: 



9 pounds of grain mixture No. 1=11.5 quarts. 



8 pounds of grain mixture No. 2= 6.G quarts. 



9 pounds of grain mixture No. 3= 7.8 quarts. 

 9 pounds of grain mixture No. 4= 6.2 quarts. 

 9 pounds of grain mixture No. 5=13.9 quarts. 



It will be noticed that when bran, brewers' grains, 

 ground oats or other comparatively bulky grain feeds enter 

 into the ration a larger measure of the feed is required. 

 In so far as possible the ration should be made up so that 

 the more bulky grain part goes with the less bulky roughage 

 part. For example, grain mixture No. 2 is better adapted 

 to "foundation" ration No. I, which contains silage, than 

 is grain mixture No. 1, so far as bulk is concerned. For 

 the same reason, another grain mixture than No. 5 would 

 be better adapted to ''foundation" ration No. IV, which 

 is already rather bulky on account of the silage. 



The question of how far silage can be made to replace 

 grain in a ration for the dairy cow without injuriously af- 

 fecting either her health or the quality of the milk is the 

 one of economic importance to the New Hampshire farmer. 



A series of experiments bearing on the above question 

 is now in progress at this Station and some interesting re- 

 sults are anticipated. 



SUMMARY. 



(1) The economic feeding of stock should be the feeder's 

 primary object. 



(2) Economic feeding must go hand in hand with sci- 

 entific feeding. 



(3) The principles of scientific feeding have been care- 

 fully worked out by skilled investigators and feeders. 



(4) The application of these scientific principles is a
