8 to 16 weeks produce soft carcasses." 
ING RESULTS FROM RICE BRAN WITH TANKAGE 
Feeding results are available from six experiments in which rice 
bran was fed with tankage and minerals with and without addi- 
tional supplements. In 2 tests the hogs were fed by the Arkansas 
station, in 1 by the Mississippi station, and in 3 by the Iberia Live- 
stock Experiment Farm, La. The work covered the period from 
1923 to 1926, inclusive. All of the 133 hogs used in the experiments 
were self-fed on rice bran, tankage, and mineral mixture by the 
free-choice method. In the Mississippi station experiment the hogs 
grazed on green-rye pasture. No record of mineral consumption was 
kept in that test. In one Iberia farm experiment the hogs grazed on 
green-eat pasture and received a daily allowance of 3.14 pounds of 
skim milk per animal. The other 4 lots, 2 at the Iberia farm and 
2 at the Arkansas station, were fed in dry lot. As in the Iberia 
farm experiment referred to, however, skim milk was fed as an addi- 
tional supplement in the latter two tests at that station. In one 
case 5 pounds and in the other 3.14 pounds was the average daily 
allowance. 
The variation in average initial weights of the pigs in the several 
experiments was from 71.26 pounds to 94.18 pounds, inclusive. The 
average initial weight of the 133 pigs was 84.14 pounds. 
The feeding results from the six experiments are summarized in

Estimated. 
The hogs are shown in four groups. The differences in the feeding 
of these groups have already been indicated. Each group on pasture 
gained at a more rapid rate than the corresponding group in dry lot.
