DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS. 13 
For the entire season of 1915, as shown in Table IV, the gains per 
acre were as follows: Lot 1, 612; lot 2, 1,456; lot 3, 2,976; lot 3a, 
2,760; lot 4, 2,772; and lot 5, 4,292 pounds. The lot that was fed 3 
per cent corn made seven times as much gain as the lot which re- 
ceived no grain. The grain consumed for each pound of gain in- 
creased with the grain ration. It required 1.5 times as much grain 
for each pound of gain where a 3 per cent corn ration was fed as it 
did where only a 1 per cent corn ration was fed. For every 100 
pounds of grain fed the 1 per cent corn lots gained 53 pounds; the 
average of the 2 per cent grain lots was 40.4 pounds; and the 3 per 
cent corn lots gained 35.3 pounds. 
When the gains made are figured at $7 per hundredweight and the 
lots charged $1.07 per hundredweight for corn and $1 for ground 
barley, the net returns per acre for alfalfa pasture were as follows : 
Lot 1, $42.84; lot 2, $72.48; lot 3, $132.91; lot Za, $120.49; lot 4, 
$126.76 ; and lot 5, $170.24. From April 26 to September 27, a period 
of 154 days, the hogs gave an average daily net return ranging from 
28 cents, where no grain was fed, to $1.10, where 3 per cent corn was 
fed. At this rate a 10-acre alfalfa field pastured with hogs getting 
a 3 per cent ration of corn would pay $11 net per day, Avhereas if no 
grain was fed the same 10-acre field would return only $2.80 per day. 
The no-grain lot paid at the rate of $42.84 an acre for alfalfa pas- 
ture. When the grain-fed lots are charged the same amount for the 
pasture, they still paid very liberally for the grain fed, as is shown in 
Table IV. 
The equivalent paid for hay by the different lots greatly increased 
with the grain ration. The no-grain lot returned an equivalent of 
$9.58 ; the 1 per cent lot, $16.21 ; the average of the 2 per cent grain 
lots, $28.21; and the 3 per cent grain lot paid $38.07 per ton, or four 
tinies as much as the no-grain lot. This fact, together with the high 
price paid for the grain, emphasizes the advisability of feeding grain 
in connection with alfalfa pasture in order to realize the highest re- 
turn from both the grain and the alfalfa crops. 
SUMMARY OF THE TWO YEARS' RESULTS. 
The results of the experiments in 1914 and 1915 with alfalfa pas- 
ture and various grain supplements are summarized in Table V. 
As two lots of hogs were used each year in each part of the test, the 
figures in Table V show the average of the results secured from four 
lots of hogs in each instance. The figures have been calculated to an 
acre basis. 
The results of two years' work show that hogs on alfalfa pasture 
without grain produced an average of 644 pounds of gain per acre. 
The same area of pasture, with the addition of 3,174 pounds of corn,
