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 corn 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 
corn 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 corn meal alone, but when mixed with one-third of its 
weight of wheat middlings, it gave much better results than 
corn meal, 
The pea meal is very rich in protein and should make a 
good supplementary feed with corn. 
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 corn.
