Table XXIII shows this very clearly. This table has been constructed 

 from Tables XI, XVIII, XIX, and XX. In it, the results from feeding 

 silage and mangels to the same cow at different times during the same 

 lactation period are compared whenever such a comparison can be made 

 during either year's work. Seventeen of these comparisons were found. 

 The gain or loss in fat is noted, and there is also noted whether more 

 or less dry matter was fed with the mangels than with the silage. Then 

 the total amounts of dry matter in the silage and the mangels was 

 determined, also the total gains or losses in butter fat. In addition, 

 the extra amounts of dry matter fed with the silage were calculated. 

 It was found that 5323.7 pounds of dry matter in silage was replaced
