grasses begin to fail, and it may be made to continue 

 in season until corn is ready." 



J. H. Grisdale, of the Central experimental farm of 

 Canada, says peas are "undoubtedly of very high value 

 as a feed for the production of good, firm bacon, and 

 for young pigs and j^reeding stock of all classes at prac- 

 tically all times. They should, however, never be fed 

 alone, and should always be ground. Pigs fed on pea 

 meal alone do not thrive, do not get fat, and produce a 

 very inferior quality of meat, dry and hard." 



Pea feeds, under various names, are by-products of 

 prepared-food factories, and vary in composition. Some 

 of them are equal to pea meal in feeding value, while 

 others are of little account. 



SOY BEANS 



Soy beans are not commonly used in pork production, 

 doubtless owing to lack of knowledge of their character- 

 istics and \-alue. While they ha\e been grown to some 

 extent for several years, only recently has their value 

 to pork makers been understood. At least four experi- 

 ment stations have made tests with soy beans for hogs. 

 All report fa\orably. The trials at the Indiana station, 

 taken with the results of other experiments, are con- 

 vincing arguments as to the efficiency of the seeds of 

 this legume when fed with corn to swine. Soy beans 

 contain 29.6 pounds of digestible protein to the 100 

 pounds of beans, and pigs fed on tliem grow rapidly.
