Miscellaneous grains. — There have now been considered 80 lots of 
hogs pastured on alfalfa supplemented with some kind of grain. Of 
these 80 lots 41 received corn, 15 received barley, 3 milo, 3 wheat, 2 
shorts, and 13 were fed mixed grain rations, each of which contained 
either corn or barley. The predominance of corn and barley as sup- 
plements to alfalfa pastures on irrigated land is thus reflected in the 
data which have been presented. Other grain feeds are important in 
certain sections (as, for example, the grain sorghums in the South- 
west) and in individual instances in all sections. The data under con- 
sideration do not afford comparisons of grains other than corn and 
barley similar to those made of those two grains in Table XIV. The 
results secured with milo, as shown in Table X, and with wheat and 
shorts, as shown in Table XI, furnish no basis for a presumption that 
these feeds are inferior to corn or barley as supplements to alfalfn 
pasture. It should be stated, however, that for economic reasons the 
use of wheat for this purpose is not generally looked upon with favor. 
The three grains which appear to be best suited for use as alfalfa - 
pasture supplements in irrigated sections are corn, barley, and the 
grain sorghums ; and, pound for pound, they probably do not differ 
materially in value for such use. At any rate, it seems certain that 
any slight differences in feeding value are of decidedly less impor- 
tance than differences in adaptation to local climatic, economic, and 
cultural conditions.
