APPLE BY-PRODUCTS AS STOCK POODS. 29 
The pomace is a palatable feed and when fed as described it 
appeared to be equal, pound for pound of dry matter, to good corn 
silage as succulent food for the daily cow. Owing to the property 
possessed by dried apple pomace of absorbing large quantities of 
water and swelling, it should never be fed dry, but should be allowed 
to soak in water for an hour or so before being fed. 
The feeding of large quantities of dried pomace or of quantities 
containing excessive amounts of apple seeds might prove injurious. 
DRIED APPLE-PECTIN PULP. 
Pbevious Investigations. 
In 1909 Shutt (129) made the following statement concerning 
moist apple-pectin pulp, samples of which he analyzed : " We should 
not consider that the nutritive value of this material was equal to 
that of the ordinary farm roots or of corn ensilage, but no doubt 
it could be used to advantage, if sound, to furnish a part of the suc- 
culent ration of the milch cow." This material contained 85 per 
cent of water. The manufacturer of the product made the follow- 
ing report : " TTe waited until our stock of roots (turnips and car- 
rots) was finished and then used the pulp. We were pleased to 
find the milk did not decrease at all. Two small pigs used to eat all 
they could find and seemed to thrive on it." 
YVarcollier (138) mentioned that the press residues, after cooking 
apple pomace with water and repressing, were utilized for the feed- 
ing of stock. Anion (38) suggested that the dried pectin residues 
be mixed with molasses for stock feeding. 
Preliminary Feeding Trial. 37 
A preliminary feeding trial was made to determine the palatability 
of the dried apple-pectin pulp, its effect upon the health of stock, 
the approximate quantity that should be fed. and the manner of pre- 
paring it. In this preliminary trial it also was possible to make a 
comparison with corn silage as to relative milk production value. 
As dried pectin pulp should prove of greatest value as a source of 
succulence for dairy cattle in the winter, it was fed wet throughout 
both experiments. The dried pulp which had been ground to a meal 
was prepared by adding to it three times its weight of water, several 
hours before feeding. 38 
In order to determine the palatability and to find out whether there 
were any detrimental effects on the animal body, the moistened pulp 39 
was fed to four cows for five days. The first day a part of the corn 
silage 40 included in their ration was replaced by the pulp: then the 
silage was entirely replaced by a relatively greater quantity of pulp. 
In the comparative milk production test, the aim was to supply 
the same quantity of dry matter in the pectin pulp as the cow re- 
ceived in the form of corn silage. A young Hoist ein in lactation 
was chosen, and the comparison between the moistened pectin pulp
