Pig-FeedEmg Experiments.
Professor j. w. Sanborn in bulletin
No. 10 gives interesting and instructive
results from pig feeding experiments car
ried on for number of years ct the Mis-
souri, Agricultural college farm OF Co
Iumbia. The experiments were made
with whole corn, cornmcal and ship
stuff The relations OF the shipstnff TO
the meal in these trials deserves atten-
ton: 03.S pounds of shipstuf give the
same grain that 100 pounds of cornmeal
produced. This has been the continuous
result for six years. The first three years
of trials were in a good cool basement
of barn and with pigs. and 100 pounds
of shipstuf gave 49, pounds gain, and
100 pounds Of cornmeal gave 1914 gain.
Professor Sanborn explains that these re-
suits are what good conditions give and
stand for profitable farming. Nor is this
all; the value of the two foods for ma
nure is compared. At rates paid in East
ern States for nitrogen, phosphoric acid
and potash in chemical manures. these
materials in the manure made from the
consumption of ton of shipstuff are
worth $13.63, and from q ton Of corn
meal &6.65. Professor Sanborn explains
that these figures are not practical values
for Missouri, but relative. and such as
to warn against the sale of our shipstuff
from home
An interesting experiment made was
feeding for lean meat. The purpose of
this trial was merely to observe how far
the character of the food modifies the
type and composition of the animal.
Shipstuf was fed against cornmeal. The
composition of these foods was as fol-
lows:

Feeding trials with Analysed foods
leads Professor Sanborn to believe that
protein has been overrated as force and
fat producer, and that carb. hydratcs
have been much moderated as fat and
force producers. He is convinced that
the carb. hydrates are fat producers in
swine to a liberal degree. The query
''does food rich in carb. hydrates and
fats tend to produce an increased pro
portion of fat to flesh?' is an important
one to consumers who have to purchase
a heavy proportion of fat for which they
have no desire.
Excessive fairness, in Professor San
born's opinion, has restricted consump-
ton to such an extent as to demand the
attention of the feeder In 1880 the
country had 80, 354, 213 swine, or 1.3
per capita of population. In 1860 we
had SS, 512, S67, OF, one per capita. In
1870 we had %, 1874, $50. or @ per capita.
-. - -
CAPITA and in 1884 but $40 per capita.
Population has gone in thirty three years
from $4,000, 900 to $4,000, and swine
from 80, 1000, 0O1 to $4,000, 900 only.
But this is not all, the exports have in
creased from over Z 900, 900 annually to
ten times this amount. Thus, explains
the professor, while we produce less per
consumer, by a heavy decline, heavy
fraction of the swine product of the
country is now exported. The character
of the product does not explain ell, but
much of the cause of the great change.
Our people are not lard or grease eaters.
As already observed, pigs fed on ship
stuffs versus corn give apparently better
muscular development from ship-stuff.
On severing the heads of corn-fed pigs
scarcely trace of lean meat was seen.
In substituted pigs it was decidedly
abundant. The substituted pigs also
carried less fat even in the fibres of lean
meat than the cornmeal- fed lot.
In summing up his experience, Pro-
lessor Sanborn says that he il convinced
that the exclusive use of cornmeaf for
feeding ration is detrimental TO hearty
muscular development, producing pig
subject to disease, distasteful to con-
s.mcrs and more costly than is necessary.
He would not be understood, however,
as implying that shipstuff is the only
good food or that corn has no place in
feeding swine.
