168 The Sugar-Beet in America 
from hogs fed on beet tops is of a desirable quality, feed- 
ing tops to them is recommended. Experiments! show 
that hogs pastured on beet tops and receiving one-third 
normal grain rations did well. Horses should not be fed 
large quantities of tops. 
SUGAR-BEET PULP 
After the beet has been sliced into shreds and most of 
the sugar extracted, pulp remains as a by-product. A 
great many experiments in this country as well as in 
Europe have been conducted to determine the value of 
this pulp. The interest in it seems to have been due not 
so much to its value as to the difficulty of disposing of 
such a great quantity of material at the factories. Ap- 
proximately 85 per cent of the original weight of the roots 
is discarded as fresh pulp, but by the time the water has 
been well drained from it and it has gone through the 
siloing process, only 25 to 35 per cent of the original weight 
of the roots remains. The tops can be dried easily into 
a rich hay in the more arid parts of the country, whereas 
it is rather expensive to dry pulp. The dried pulp is less 
than twice as valuable for feed as the cured tops. When 
time cannot be spared to silo the tops and when a suc- 
culent feed is desired during the winter, the pulp may be 
the more economical even though it is usually necessary 
to pay a small sum for it. Table V shows the relative 
value of tops and, pulp. 
Only a small part of the pulp is fed just as it comes
