PIG-FEEDING EXPERIMENTS
By John M. Scott

The feeding experiments given in this bulletin were carried on between
December, 1910, and August, 1911. It would not be correct, however, to com-
pare the results obtained from a feeding test carried on during the winter
with one conducted during the summer season.
Experiment No. 1
The first experiment was begun on December 13, 1910, and lasted sixty
days, closing on February 11, 1911. In this experiment the pigs were divided
into five lots of five pigs each, as nearly equal in quality and weight as pos-
sible. The pigs in Lot I were fed velvet beans in the pod; Lot II were fed
equal parts by weight of velvet beans in the pod and green Japanese cane;
Lot III were fed one part of velvet beans in the pod and two parts of
Japanese cane; Lot IV were fed Japanese cane only; Lot V were fed equal
parts of velvet beans in the pod and sweet potatoes. At the beginning of
the experiment the pigs in Lot I weighed 230 pounds; Lot II weighed 230
pounds; Lot III weighed 235 pounds; Lot IV weighed 215 pounds; and Lot V
weighed 215 pounds. During the sixty days, Lot I gained 25 pounds; Lot II
gained 4.3 pounds; Lot III lost 7.7 pounds; Lot IV lost 61 pounds; and Lot
V gained 12.3 pounds.
It will be seen from these weights that none of the pigs made large
gains. The heaviest loss in weight was with Lot IV, which was fed Japanese
cane only. We need not be surprised that the pigs did not make a gain
during this feeding test. The analysis of Japanese cane shows that it con-
tains a very small amount of protein, only 1.37 per cent. Since these pigs
were quite small, averaging about 45 pounds per head, and since protein is
indispensable for the development and growth of young animals, it will be
seen that Japanese cane does not supply sufficient bone and muscle-producing
material to make the necessary growth. Even Lot III, which was fed one
part velvet beans and two parts Japanese cane, lost in weight during the
sixty days, but the loss was not so great as with the Japanese cane only.


December 30, 1911









The velvet beans in this case, supplied some protein, but apparently not
sufficient for the needs of the animals.
Experiment No. 2
The second experiment began on March 21, 1911, and closed June 16,
1911, lasting ninety days. The pigs used in this experiment were divided
into four lots of five 'pigs each. The pigs of Lot I were fed shelled corn
only; those of Lot II were fed equal parts of shelled corn and cull velvet
beans; Lot III were fed shelled corn, cull velvet beans and shorts, equal
parts of each; Lot IV were fed equal parts of shelled corn and cull velvet
beans, and all the green sorghum the pigs would eat. The feeding with
green sorghum began on May 9, 1911. The cull velvet beans used in this
experiment were the refuse taken from the seed velvet beans. The beans
were first run through a bean huller to remove the hulls, they were then
run through a screen of % inch mesh. The beans that passed through the
screen were considered as culls. These consisted of immature, shrivelled
and broken beans. After feeding in the morning, the feeds for the evening
meal were weighed out and put in water to soak until the night feeding, and
so on.
At the beginning of this experiment, the pigs in Lot I weighed 291
pounds; Lot II weighed 266.6 pounds; Lot III weighed 274.6 pounds; and Lot
IV weighed 265.6 pounds. During the ninety days the pigs in Lot I gained
115.6 pounds; Lot II, 78.4 pounds; Lot III, 116 pounds; and Lot IV, 108 pounds.
Experiment No. 3
This was carried on with 17 head of pigs. At the beginning of this ex-
periment the pigs were about three months of age. The 17 pigs weighed
590 pounds, the average weight being 34.7. The feeds were equal parts of
shelled corn and shorts by weight, and about 2 pounds of milk per day
per head, together with all the green sorghum they would eat. The experi-
ment closed September 22, 1911, after lasting 114 days, at which time the
pigs weighed 2462 pounds, making a total gain of 1872 pounds, or an average
daily gain of nearly one pound.
Experiment No. 4
This began July 18, 1911, and closed August 29, 1911, lasting 43 days.
The 10 pigs at the beginning of the experiment weighed 990 pounds, aver-
aging 99 pounds per head. The total weight at the close of the experiment.
was 1329 pounds, making a total gain of 339 pounds, or an average daily
gain pen head in 43 days of nearly eight-tenths of a pound. The feeds
given were shelled corn and all the green sorghum the pigs would eat.
