DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS.

ment that corn at $1.07 per hundredweight is cheaper feed than 
ground barley at $i per hundredweight. The average of the two 
years' results, and especially the 1915 results, seems to indicate very 
strongly that, pound for pound, ground barley is approximately 
equal to corn as feed for hogs in supplementing alfalfa pasture. 
The two-year average net return for alfalfa pasture was $15.08 
where no grain was fed. If the grain-fed lots are charged this 
amount for pasture, the net returns for each 100 pounds of grain 
fed were as follows: 1 per cent corn lot, $1.86; 2 per cent corn lot, 
$2.16 ; 2 per cent barley lot, $2.06 ; and the 3 per cent corn lot, $2.03. 
It appears from this that 2 pounds of corn per day for each 100 
pounds of live weight is the most satisfactory ration of corn for hogs

on alfalfa pasture in order to get the highest return from both the 
corn and alfalfa pasture. This is true when the feeder can get only 
a limited amount of corn, but when an abundant supply of corn is 
available at not more than $1.07 per hundredweight, it may be de- 
sirable to feed about 3 pounds of corn to each 100 pounds of live 
weight. Hogs fed a 3 per cent ration of corn will make a faster 
growth than those fed a 2 per cent ration and hence be ready for the 
market earlier. As a saving of time lessens risk and also saves in- 
terest on investment, this is a factor to be considered. Figure 3 
shows a representative hog from the lot getting no grain, and one 
each from lots getting 1 per cent, 2 per cent, and 3 per cent of corn 
in 1914.
