152 RESULTS OF EXPERIMENTS IN SWINE FEEDING 
The amount of dry matter required for a pound of gain 
was twice as great in the corn group as in the mixed ration 
group. 
The mixed ration group made 4.2 times as great a gain 
as the pigs in the corn group. 
On an average, the thigh-bones of the mixed-ration group 
were 50 per cent stronger than those from the corn group. 
The constitution of the pigs in the corn group was seriously 
impaired. 
Finally, it is highly impracticable to raise growing pigs 
upon a ration of corn alone. 
Soy-Bean Meal and Wheat Middlings——Humphrey and 
Fuller, of the Wisconsin Experiment Station, report three 
tests in which soy-bean meal was compared with wheat 
middlings as a supplement to corn. The sov bean is very 
rich in protein and fat, and the object of the experiment was 
to compare it with wheat middlings, which are generally 
recognized as being a good supplement to corn. 
Two pounds of corn meal were fed with each pound of 
soy-bean meal or wheat middlings, and skim-milk was also fed 
to both lots. Part of the time the hogs were on pasture, and 
part of the time in pens. The authors draw the following 
conclusions : 
“ Soy-bean meal makes an excellent supplement to corn 
meal for growing and fattening pigs.” 
“ Soy-hbean meal is from & to 10 per cent more valuable 
than wheat middlings for economical pork production when the 
cost. of the two feeds is the same.” 
“For firmness, fine grain and texture of flesh, and even 
distribution of fat and lean, the ration of wheat. middlings 
and corm meal is superior to that of soy beans and corm meal.” 
Looking over these conclusions, we must admit that soy-
