RESULTS OF SOFT-PORK INVESTIGATIONS, II 37 
Of the two lots on pasture the one receiving milk gained more 
rapidly, and the same was true of those fed in dry lot. With the 
exception of the Iberia farm group fed on pasture the rates of gain 
were under 1 pound a day. The mineral mixture consumed per 100 
pounds gain in the Mississippi experiment was estimated at 10 
pounds. It is obvious that the feed consumption per unit of gain in 
the Mississippi station experiment, as well as in the Iberia farm test 
on pasture, was considerably less than in the two in dry lot. Ap- 
proximately from 25 to 30 per cent less grain feed per unit of gain 
was consumed by the 40 hogs on pasture than by the 93 hogs in dry 
lot. In all cases, however, the feed consumption was high in rela- 
tion to the gain made by the hogs. This fact considered in connec- 
tion with the generally low rates of gain suggests that the value of 
rice bran as a fattening feed for hogs is below the standard of 
first-class feeds. 
F. RICE BRAN WITH TANKAGE FOLLOWED BY CORN WITH TANKAGE 
The problem of hardening hogs fed on rice bran is comparable in 
most respects to that on rice polish. The experiments throughout the 
work with rice bran have paralleled those with rice polish and the 
results with respect to firmness are very similar. The initial weights 
of the hogs on which results are presented range from 50 to 114 
pounds. The eight-week feeding period on rice bran was followed 
by eight weeks on corn or brewers' rice. As shown in the feeding 
outline of the experiments, a number of supplements were used with 
these feeds. 
HARDENING RESULTS FROM CORN WITH SUPPLEMENTS 
A total of 44 hogs were fed in 5 experiments on rations of rice 
bran, tankage, and minerals for 8 weeks, followed by corn, tankage, 
and minerals for 8 weeks, with the exception of 3 hogs in the Missis- 
sippi experiment which were fed in 5 and 11 week periods, respec- 
tively. Further feeding details for the several experiments are as 
follows : 
Arkansas, 1925, self-fed, free choice, dry lot. 
Arkansas, 1926, self -fed, free choice, dry lot. 
Iberia, 1925, self-fed, free choice, on oat pasture and given a daily supple- 
mental feed of 3.14 pounds of skim milk per animal. 
Iberia, 1926, self-fed, free choice, dry lot, and given a daily supplemental 
feed of 3.14 pounds of skim milk per animal. 
Mississippi, 1924, self -fed, free choice, on rye pasture. 
The data on weights, gains, and firmness are give in Table 19. As 
in the experiments on the effects of rice bran shown in Table 17, the 
hogs in the Iberia farm experiments, which received brewers' rice 
before the experimental period, had a rather firm fat at the start of 
the softening period. The average gains on rice bran were higher 
than in other lots, and those on corn were of only average amount, 
yet the hogs were among the firmest of all the experiments. The 
gains on rice bran were usually lower than on rice polish. Further 
discussion on the feeding value of rice bran is given on page 34. The 
difference in the firmness of the hogs in the two Arkansas station 
experiments may be attributed to a considerable degree to the differ- 
ence in oil content of the rice bran. In the 1925 experiment the oil
