It will bo seen from the coefficients that while the dry matter 

 in the molasses pulp has a higlier digestibility than that in the 

 plain pulp, and while the dry matter in the corn meal shows an 

 increased digestibility over either of the pulps, the digestibility 

 of the total organic nutrients in one ton of the several feeds 

 does not vary widely. This is explained on the ground that the 

 molasses pulp contains noticeably more ash than the plain pulp, 

 and that the corn meal has some G per cent, more water than 

 the dried pulps. On the basis of digestible organic nutrients 

 in one ton, it would appear that the corn meal was substantially 

 5 per cent, more valuable than the average of the two pulps. 

 Calculations made on the basis of net energy value show the 

 corn meal to furnish 20 per cent, more energy than the dried 

 pulp. This is due to the increased energy assumed to be re- 

 quired to digest the fiber contained in the pulp. It is doubtful, 

 however, if the soft beet fiber causes as much energy loss as do 

 the harder fibers of the hays and straw. One may conclude 

 that in practical feeding trials comparatively little difference 

 would be noted, pound for pound, betv/een the two feeds, espe- 

 cially if the amounts of each feed fed did not exceed 5 pounds 

 dailv to each animal.
