bean lot $3.46, a showing decidedly in favor of the lat- 

 ter. The percentage of protein in the two meals is 

 practically the same. 



Three different trials were made at the Wisconsin sta- 

 tion (Annnal Report. 1906) to compare the value of 

 soy bean meal and wheat middlings as a supplement to 

 corn for growing and fattening swine. A summary of 

 the conclusions to which these tests led, as given by Pro- 

 fessors George C. Humphrey and J. G. Fuller, is : 



1. Soy bean meal makes an excellent supplement to 

 corn meal for growing and fattening pigs. 



2. Soy bean meal is from 8 to 10 per cent more 

 valuable than wheat middlings for economical pork pro- 

 duction when the cost of the two feeds is the same. 



3. Soy bean meal mixed with corn meal in the pro- 

 portion of I :2 produces greater gains than wheat mid- 

 dlings and corn meal in the same proportion. 



4. In feeding equal amounts of the two rations, soy 

 beans and corn meal supply a slightly higher per cent 

 of dry matter and digestible matter than wheat middlings 

 and corn meal. 



5. For firmness, fine grain and texture of flesh, and 

 even distribution of fat and lean, the ration of wheat 

 middlings and corn meal is superior to that of soy beans 

 and corn meal. 



As to the flesh of the test hogs when dressed, the re- 

 port gives these observations: "The fir.st difference noted 

 in handling the carcasses was the soft and flabby condi- 

 tion of the lot fed corn meal and soy bean meal, and the 

 firmness of flesh of the lot fed corn meal and wheat mid- 

 dlings.
