The average initial weights in experiments 2 and 5 were lower than 
in the others. While the average daily gains were also lower, the feed 
utilization was considerably better in these experiments than in the 
others. More economical use of feed is commonly expected, of 
course, with younger hogs than with older ones, and the results 
obtained here probably can be accounted for in this way. 
The general average of 458.81 pounds of feed consumed per 100 
pounds gain is a figure which must be regarded as very satisfactory. 
It indicates clearly that ground soy beans fed under conditions such 
as prevailed in these experiments constitute a valuable protein sup- 
plement to corn for use in fattening well-grown pigs, 
E. RICE BRAN WITH TANKAGE 
Rice bran is one of the several by-products of rice milling which 
are used extensively in certain sections of the country as hog feeds. 
Results obtained at the Arkansas (i), Texas (9), and California (6) 
stations have shown that rice bran when fed as the basal feed pro- 
duces soft carcasses. In the present investigations experiments were 
conducted to determine the degree of softness which develops on rice 
bran as compared to other softening feeds. 
NATURE OF THE FEED 
The average composition of the rice bran used in the experiments 
and, for comparison, that of rice polish, are given in Table 16.
