DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS. 15 



ment that corn at $1.07 per hundredweight is cheaper feed than 

 ground barley at $1 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 $45.08 

 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.
