meals wet with water to a medium thick slop; first, to 

 determine the value of soy beans as a supplement to corn 

 in pork production and to encourage farmers to grow 

 their own protein for hogs; second, to compare soy 

 beans with wheat middlings and tankage as supplements 

 to corn, and add new data to previous experiments with 

 these feeds ; third, to emphasize the deficiency of corn 

 as a sole ration for pork production and point out more 

 economical methods of feeding and utilizing corn. 



The test showed that it required less feed per loo 

 pounds gain where soy beans were fed than in any other 

 ration considered, while in this lot the gains, 402 pounds, 

 were 120 per cent greater than the gain in the corn-fed 

 lot and 10 per cent more than the gain in any other lot 

 in the test. The pigs fed more uniformly and developed 

 more evenly than any one of the other lots. The Kansas 

 station reports uniformly successful results from the use 

 of soy beans in connection with Kafir-corn and Indian 

 corn. A resume of the results there shows a gain, 

 where pigs received soy beans as a supplement, varying 

 from 14.6 to 181. 7 per cent over corresponding lots fed 

 corn or Kafir-corn alone. 



"Indiana swine growers," says Professor Skinner, 

 "would do well to investigate the merits of soy beans. 

 They can be easily grown and will furnish a home-grown 

 supply of protein in a very desirable form. Farmers will 

 find them to be a very valuable adjunct to corn as shown 

 by results. A yield of 20 bushels per acre means ap- 

 proximately 360 pounds of digestible protein, while 20 

 bushels of wheat per acre would yield 120 pounds of 

 digestible protein. Another point in favor of soy beans
