FEEDING DRIED PRESSED POTATOES TO SWINE.

13 pounds difference in favor of the hogs in the check lot at the close 
of the test. The pigs in Lot IV were evidently as heavy feeders as 
those in the check lot, but it is impossible for pigs to consume very 
large amounts of the dried pressed potato on account of the bulkiness 
of the feeds. The pigs in Lot IV consumed a daily ration of 5.7 
pounds, made a daily gain of 1.32 pounds, and required 428 pounds 
of feed to produce 100 pounds of gain. 
The pigs in Lot III, receiving dried pressed potato and oil meal, 
consumed less feed than any other lot in the experiment. It might 
be concluded from 
this that the ration 
was the least palat- 
able and least efficient 
of any of the rations 
fed. This, however, 
is not true, because 
the pigs in Lot II, re- 
ceiving dried pressed 
potato and tankage, 
ate more feed than the 
pigs receiving dried 
pressed potato and 
oil meal, but made 
smaller gains. This 
tends to prove that 
the potato ration con- 
taining oil meal is 
more efficient in pro- 
ducing gains than the 
potato ration contain- 
ing tankage, although 
the pigs ate less of 
the potato and oil-meal feed. Furthermore, the pigs in Lot III 
possessed a higher degree of finish than the potato and tankage pigs 
(Lot II), although they were not equal to the potato and fish-meal 
pigs (Lot IV) in this respect. The pigs in Lot III consumed a 
daily ration of 5.3 pounds, made a daily gain of 0.91 pound, and 
required 584 pounds of feed to produce 100 pounds of gain. 
The pigs in Lot II, which were fed dried pressed potato and 
tankage, consumed enough feed to put them in higher condition 
than they were in at the close of the feeding test. The showing 
that these pigs made can not be called poor, but it is evident that 
tankage is not as efficient a protein supplement to use with dried 
pressed potato as some of the other supplements used in this experi- 
ment. The pigs in Lot II returned a smaller amount of gain for the
