152 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



The amount of dry matter required for a pound of gain 

 was twice as great in the com group as in the mixed ration 

 group. 



The mixed ration group made 4.2 times as great a gain 

 as the pigs in the com group. 



On an average, the thigh-bones of the mixed-ration group 

 were 50 per cent stronger than those from the com group. 



The constitution of the pigs in the com group was seriously 

 impaired. 



Finally, it is highly impracticable to raise growing pigs 

 upon a ration of com 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 com. The soy 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 com. 



Two jDounds 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 com 

 meal for growing and fattening pigs." 



" Soy-bean meal is from 8 to 10 per cent more valuable 

 than wheat middlings for economical pork production when the 

 co'st 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 com meal is superior to that of soy beans and com meal." 



Looking over these conclusions, we must admit that soy-
