Summary ok the Results. 



Composition of the Feeds (Per Cent.). 



Digestibility of the Feeds (Per Cent.). 



The analj^sis and digestibility of the haj^ were made in con- 

 nection Avith a series of digestion experiments at the station. 

 It appeared to contain rather more galactan than other 

 samples examined. ^ 



A previous complete analysis of alsike clover seed does 

 not appear to l^e recorded. It contained a high percentage 

 of protein and a normal amount of galactan. 



The results of the digestion experiment with the three 

 sheep show the tofal dry matter of the clover seed meal to 

 have been fairly well digested, although the coefficients are 

 noticeably lower than those on record for soy beans, peas, 

 vetch and lupine (85 to 90 per cent.). 



The galactan in the hay is shown to be 75 per cent, diges- 

 tible. Because of the small quantity present, the results 

 are of minor importance. All three sheep digested the 

 gahictan in the clover seed quite thoroughly. Such a result 

 was to have been expected, for the reason that in the seed 

 the galactan is supposed to be comparatively free from in- 



1 It may be assumed tliat the galactan belongs almost wholly to the nitrogen-free 

 extract matter. 



- Whether the substance obtained was pure galactan, or consisted partly of inipuri- 

 tii-s tliat it was not possible to remove, it is dillicult to say. Liudscy and Holland 

 found a trille liss than 1 per cent, in anotlier sain])le.
