DISPOSAL OP IRRIGATED CROPS THROUGH THE USE OF HOGS. 17 
experiments. One is to charge the pigs with only the feed and the 
other is to charge the pigs with both feed and the loss in weight of 
the sows. The second method is used here. 
In 1914 two sows and 14 pigs were put on the alfalfa pasture plat 
on May 4. On this date the two sows weighed a total of 702 pounds 
and the 14 pigs a total of 164 pounds. The experiment closed on July 
3. At this date one sow still remained on the plat, while the other One 
had been taken off on June 19. The final weight of the two sows was 
603 pounds, or 99 pounds less than the initial weight. The 14 pigs 
weighed a total of 636 pounds. They had increased in weight 472 
pounds in 60 days. The total initial weight of the sows and pigs 
was 866 and their total final weight 1,239 pounds, or a total increase 
of 373 pounds for the lot. The lot was fed 1,176 pounds of corn. 
The 373 pounds gain at $7 per hundredweight is worth $26.11. De- 
ducting from this the cost of 1,176 pounds of corn at $1.07 per hun- 
dredweight, or $12.58, leaves a return of $13.53 for one-fourth acre 
of alfalfa pasture for 60 days, or a daily return of 90 cents per acre. 
The sows and pigs ate 3.02 pounds of corn for each pound of net 
gain. With corn at $1.07 per hundredweight and alfalfa pasture 
at $7 an acre for 60 days, 100 pounds of gain cost $3.83. This lot 
paid the equivalent of $19.02 a ton for alfalfa hay. A tabulated 
statement of this lot is given in the first column of Tables VI 
and VII. 
In the 1915 tests, which began April 27 and ended June 26, there 
were three lots of two sows and litters each. One lot was fed ground 
barley and the other two lots were fed corn. They were fed grain 
at the rate of about 2 pounds daily for each 100 pounds of live 
weight. In two of the lots old sows were used and in the other gilts 
were used. The total initial weight of lot 6, which received ground 
barley, was 760 pounds. The sows weighed 702 and the 17 pigs 
58 pounds. One sow was taken off on June 9. The other remained 
until the close of the experiment. The total final weight was 1,178 
pounds, or a total gain of 418 pounds. The sows lost 28 pounds 
and the pigs gained 446 pounds. A total of 982 pounds of ground 
barley was fed to this lot. From each 100 pounds of grain fed 
this lot produced 42.5 pounds of gain. After paying $1 per hun- 
dredweight for the barley fed, the lot still paid at the rate of $1.30 
daily for an acre of alfalfa pasture. In lot 7, which was fed corn, 
the initial weight of the two sows was 873 pounds and of the 
15 pigs 83 pounds, or a total of 956 pounds. The old sows were 
taken off the plat on June 9. At this date they weighed 780 pounds, 
or 93 pounds less than they did when the experiment began. The 
final weight of the pigs was 574 pounds, their increase being 491 
pounds. The total increase in weight of the lot was 398 pounds.
