CHAPTER XXI. 

 VARIOUS GRAINS, MEALS, AND BY-PRODUCTS. 



Peas or Canada Field Peas. — This grain is comparatively 

 little known in the United States, and is used to a smaller 

 extent for pig feeding in Canada than it was some years ago, 

 mainly owing to the high price it commands for other purposes. 

 (Fig. 41.) 



At the Utah Experiment Station, hogs fed ground peas and 

 bran, equal parts, made an average daily gain of 1.09 pounds 

 and required 363 pounds of meal for 100 pounds of gain; 

 while hogs fed com and bran made an average daily gain of .63 

 pound and required 455 pounds of meal for 100 pounds of 

 gain. 



At the South Dakota Station, the daily gain of pigs fed 

 whole soaked peas was 1.21 pounds, and for soaked corn meal 

 1.40 pounds; but the grain required for 100 pounds gain 

 was 421 pounds for the pea group and 458 pounds for the 

 com lot. 



The Ontario Agricultural College found that feeding pea 

 meal alone was injurious to pigs, the heavy, close nature of 

 the meal making it indigestible. This peculiarity of pea meal 

 is generally recognized. Pea meal alone was less satisfactory 

 than com meal alone, but when mixed with one-third of its 

 weight of wheat middlings, it gave much better results than 

 com meal. 



The pea meal is very rich in protein and should make a 

 good supplementary feed with com. 



Barley. — Barley is richer in bone- and muscle-forming con- 

 stituents than corn, having a higher percentage of ash and 

 protein. In fattening constituents it is scarcely equal to com.
