Referring again to the data secured from the 1903 and 19(14 experiments, we 

 find that the eighteen lambs of Lot IV received a ration of concentrates consist- 

 ing of dried molasses-beet-pulp 3 parts and linseed meal 1 part, while the ration 

 of Lot V containing the same number of lambs consisted of dried beet pulp 3 parts 

 and linseed meal 1 part. During the eighty-five day test, the lambs receiving 

 dried molasses-beet-pulp gained 525 lbs. and those receiving dried beet pulp 509 

 lbs., an increase of 16 lbs. in favor of the former. The amounts of concentrates 

 consumed were exactly the same, but the lambs receiving dried beet pulp con- 

 sumed 156.75 lbs. more clover hay. The cost of grain per cwt. was $4.15 where 

 molasses-beet-pulp was used, and $4.06 with the dried beet pulp. Though the 

 former made slightly the larger increase in live weight in this instance, it was not 

 sufficient to offset the additional cost of the molasses-beet-pulp. Observations 

 concerning the relative palatability of these two foodstuffs have been made from 

 time to time in which sheep seem to show a preference for the dried molasses-beet- 

 pulp.

(The samples taken for analysis were secured by saving a small amount of 

 pulp from that used each week during the experiment in mixing the rations. The 

 composite sample therefore, contained material from twelve different lots.)

"It will be noted that the niolasses-beet-pulp carries a slightly lower percentage 

 of water than does the plain white pulp. It should be a trifle more economical 

 and desirous from this standpoint. It will again be noticed that the molasses pulp 

 contains more total i)rotein than does the i)lain pulp. This seems to be caused 

 by the high percentage of amido bodies in the molasses, such an amount, in fact, 

 as to make the per cent of true proteids in the molasses pulp considerably less 

 than in the white pulp. It has been customary to consider the amido bodies to have 

 practically no feeding value and from this standpoint the plain white pulp would 

 of course be superior. It has seemed to me, however, th-it, inasmuch as many of 

 the amido bodies make good culture media for l)acteria, they might be considered 

 as 'sparers' of true proteid in which case we should be compelled to give them 

 a value in the ration. This value cannot, however, equal the value of a true 

 j)roteid. From the standpoint of fiber, the molasses pulp is again somewhat 

 superior to the plain pulj) in that it contains a less amount of this material. It 

 seemed quite reasonable lo suppose that the higher the fiber content in a feed the 

 less will be the net available energy of that feed." 



"The other point in which the laboratory analysis shows a difference is in the 

 amount of sugars present in the samples. It will be noted that the molasses pulp 

 i:ontains slightly more than twice as much total sugar as does the plain pulp. 

 This should tend to increase the net available energy of the molasses pulp. It 

 is doubtful if the presence of a greater per cent of sugar in the molasses pulp 

 can be said to in any way increase the digestibility of that pulp. Whether the
