DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS. 11 
the corn fed. By this method of calculation it can be shown that lot 
2 paid $1.64, lot 3, $2, and lot 4, $1.91 per hundredweight for the 
grain fed. 
The quantity of grain required with alfalfa pasture to produce 
a pound of pork varied from 2.36 pounds in lot 2 to 3.02 pounds in 
lot 5, the quantity increasing with the total quantity of grain fed. 
The cost per 100 pounds of gain varied from $2.22 in lot 1 to $3.61 in 
lot 5. The total and daily net return per acre of alfalfa pasture 
increased with the amount of grain fed. Lot 1, with no grain, paid 
$47.32 an acre for the alfalfa pasture. This was much more than the 
hay crop would have sold for in the stack had it been harvested. 
This partly explains why many farmers are content to carry hogs 
through the summer on alfalfa pasture with little or no grain. After 
paying for the grain fed, lot 2 paid $67.93; lot 3, $124.07; lot 4, 
$117.16; and lot 5, $166.25 per acre of alfalfa pasture for the season. 
The daily net returns per acre of alfalfa increased from 30 cents 
where no grain was fed to $1.06 where about 3 per cent of corn 
was fed. 
Five plats of alfalfa in the same field where these experiments were 
conducted yielded at the rate of 6.56 tons of hay per acre in four cut- 
tings. On the basis of this yield, if the cost of harvesting the hay 
crop is equal to the cost of caring for the hogs, lot 1 paid $7.22 a ton 
for alfalfa hay ; lot 2 paid $13.38 ; lot 3, $19.21 ; lot 4, $17.86 ; and lot 
5, $25.30. The manure left on the land is also of some value and 
should be considered in favor of the practice of pasturing hogs on 
alfalfa. 
EXPEKIMENTS IN 1915. 
The 1914 pasturing experiments were repeated during the summer 
of 1915, with the addition of one more lot (3a) fed 2 per cent corn. 
These pasturing experiments were conducted on the same alfalfa 
plats that were used in 1914, with the exception of one, lot 3a, which 
was on third-year alfalfa. The same general plan was followed in 
1915 as in 1914, as described aboA^e. 
The 1915 season was very backward and suffered many disadvan- 
tages. The hogs were put on pasture on April 26. The first two 
weeks the hogs did well, but on May 18 a foot of snow fell and the 
temperature dropped to 29° F. This made it necessary to remove 
the hogs from the plats for seven days, during which time each lot 
was kept separately and fed the regular amount of grain. Again, 
on August 6, a severe hailstorm did a great deal of damage to the 
alfalfa. The damage done on the pasture plats was not as great as 
on the plats which were left for hay. There is little doubt that the 
hogs obtained more feed from the pastured plats than was harvested
