DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS. 25 
of 2.47 pounds of corn in addition to alfalfa pasture to produce 
1 pound of pork. If the gains are valued at 7 cents a pound and corn 
at 60 cents a bushel, or $1.07 a hundredweight, the average annual 
return was $138.75 per acre of alfalfa pasture. If the corn fed is 
valued at 60 cents a bushel and the alfalfa pasture at $15 an acre 
the average cost of 100 pounds of gain was $3.11. If the average 
yield of the alfalfa plats iri the same field is assumed to represent 
the yield of the pastured plats the hogs paid an equivalent of $25.13 
per ton of hay. 
In two years' experiments with alfalfa pasture, with and without 
supplemental feed, an average annual return of $45.08 per acre was 
secured where no supplement was used, as compared with $70.20 
where a 1 per cent ration of corn was used — $128.49 from a 2 per cent 
ration of corn — $121.96 from a 2 per cent ration of barley, and 
$168.25 from a 3 per cent ration of corn. The rate of gain and the 
carrying capacity of the pasture increased with the quantity of 
grain fed. Ground barley appeared to be as good, pound for pound, 
as shelled corn as a feed for hogs on alfalfa pasture. 
Sows and pigs on alfalfa pasture, with a 2 per cent ration of grain, 
made an average gain of 1,574 pounds per acre of alfalfa pasture 
from May 1 to July 1, or a net return of $66.84 per acre. When 
corn was used the return varied from $54.11 to $69.97 per acre, and 
when barley was used the return was $77.76 per acre. 
In three years' experiments, hogging corn without supplementary 
feed produced an average of 896 pounds of gain, worth $65.72 per 
acre, or $1.50 per hundredweight of the estimated yield of corn. 
In two years' experiments, hogging corn without supplementary 
feed produced an average of 744 pounds of gain, worth $52.08 per 
acre, as compared with 930 pounds of gain, worth $65.10, where the 
hogs had access to alfalfa pasture, and 1,029 pounds of gain, worth 
$72.03, where the hogs were fed tankage in addition to the corn. 
Where no supplementary feed was used the hogs paid $1.34 per hun- 
dredweight for the estimated yield of corn, as compared with $1.55 
per hundredweight where the hogs had access to alfalfa pasture and 
$1.50 per hundredweight where tankage was used. The use of either 
alfalfa or tankage resulted in more rapid and cheaper gains than 
were secured where no supplementary feed was used.
