6 The Colorado Experiment Station. 
barley, corn and alfalfa lot required 435 pounds of grain and 67 
pounds of hay for 100 pounds gain; while the barley and shorts 
lot required 457 pounds of grain for 100 pounds gain. Both 
rations were very satisfactory. 
GRAIN AND TANKAGE. 
Lots VII and VIII were fed barley and tankage, and corn and 
tankage respectively, ten pounds of grain being fed for each pound 
of tankage. The corn and tankage produced slightly better results 
than barley and tankage, and both rations were good, coming next 
to lots III and VI in point of economy. 
BARLEY AND WHEAT, EQUAL PARTS. 
This ration gave good gains, and required only 476 pounds 
of feed for 100 pounds gain in live weight. But with wheat at any 
ordinary figure, the cost of the ration is high. If cheap wheat can 
be gotten—that is, wheat at the price of corn or barley, the wheat 
and barley ration will prove a satisfactory one. Barley offsets 
the tendency towards production of soft and flabby flesh which 
wheat favors, and the two together give good gains. 
BARLEY AND PEAS, EQUAL PARTS. 
This ration is not equal in production of gain to any of the 
other rations except the beet rations, and one alfalfa hay ration. 
Also, the amount of feed required for gain was 482 pounds—con¬ 
siderably greater than that required by the other rations in which 
grain or grain by products only were fed. And since peas are 
ordinarily higher in price than corn or the small grains, the ration 
does not prove economical. 
This, of course, does not mean that a ration of barley fed to 
swine hogging off peas in the field might not prove economical. 
These results apply only to threshed peas when fed with barley to 
hogs that are confined to feed yards. 
The following Table “B” gives the digestible nutrients re¬ 
quired for one hundred pounds of gain in live weight. The nutritive 
ratio shows the proportion of protein to carbo-hydrates and fat in 
each ration; for example with Eot I, the nutritive ratio is 7.8; that 
is, there was one pound of protein to every 7.8 pounds of carbo¬ 
hydrates and fat in the ration.
