HATCH EXPERIMENT STATION, 



[Jan. 



Especially Avide variations are noted in the case of the old 

 sheep. Sheep II. seemed to have a strong digestion, while 

 Sheep I., judging from the results, was slightly out of con- 

 dition. Such extreme variations are not apparent in case 

 of the young sheep. In both experiments considerable dif- 

 ficulty was experienced in digesting the crude fiber, due 

 probably to the fact that it was derived largely from cotton- 

 seed hulls. The protein was moderately digestible, while 

 the extract matter and fat yielded fairly high coefficients. In 

 general it may be said that the dairy cake was only moder- 

 ately digested, and possessed a nutritive value similar to 

 standard wheat middlings. An experiment with Bibby's cake 

 fed to four dairy cows has been completed, and the relative 

 commercial and nutritive value of this concentrate will be 

 more fully discussed in that connection. 



Dried Molasses-heet-puJp . — This material, manufactured 

 by the Alma Sugar Company of Alma, Mich., consisted of 

 beet pulp and crude molasses dried. ^ In appearance it 

 resembled ordinary black tea. The analysis showed it to be 

 low in protein and high in fiber and extract matter ; only 

 traces of fat were found. A more detailed analysis of the 

 product showed that the crude protein consisted of 7.01 per 

 cent, of true albuminoids and 2.90 per cent, of amides; the 

 extract matter contained 13.80 per cent, of cane sugar and 

 1.83 per cent, of dextrose. The pentosans (18.40 per cent. ) 

 were in all probability largely in the form of a hemi-cellu- 

 lose, and would also be included in the extract matter. The 

 above figures are based on the material in its natural state, 

 with 8.58 per cent, moisture. The results of the experi- 

 ment with two old sheep follow : —
