CORN NOT ALONE FOR HOGS
Some Remarkable Results of
Feeding Experiments at the
Iowa Station.
BY 1. E. CARTER,

During the past two years Professors
Kennedy and Robbins of the state sta
ton conducted three experiments to
determine the most economical meth
DDS of combining corn and the different
supplements and to find out the re-
spective merits of clover and timothy
pastures when the above rations were
fed. The main difference in the first
two experiments was the age of hogs.
The third experiment was primarily
to compare clover and timothy pas
lures, but since the same feeds used in
the two former experiments appeared
In this test, some conclusions concern
ing corn and the supplements may also
be safely drawn.
The conclusions arrived at from the
various experiments are as follows:
Meat meal and tankage of similar
chemical composition are almost equal,
pound for pound, as corn ration for
fattening hogs.
The hogs fed meat meal and tankage
as 10 per cent of their ration with corn
required forty pounds Of this nitrogen
GUS concentrate for each 100 pounds
gained.
A ration composed of corn with
either meat meal or tankage produced
from 25 to 40 per cent faster gains
on quite mature hogs In every case
the number of pounds of feed required
per 100 pounds gain was decidedly less
with a mixed ration.
A ration of one-half corn and one
half shorts produced greater gains
with less feed per 100 pounds gain
than a ration Of two-thirds corn and
One-third shorts.
A ration composed of corn two parts,
barley one part and shorts one part
produced 100 pounds gain at fully as
low cost as the ration containing
meat meal or tankage in conjunction
with corn.
Barley is therefore an economical
feed when combined with corn and
shorts. and when finishing hogs for
market.
This experiment shows that the ra-
ton containing a much larger proper
ton of protein to the carbohydrates
and fats than is found in corn is the
best--in other words, that it is not best
to feed corn alone.
In dry lot feeding young pigs getting
meat meal or tankage to the extent of
1923 per cent of their ration with
rapid gains than those fed on any 9TH
err combination.
In every instance the number of
pounds of feed required was decidedly
less with a mixed ration.
The proportion 10 to 1 produced the
most rapid gains and the greatest total
profit, while the proportion of to /
required the least total amount of feed
but the greatest amount of meat meal.
Meat meal and tankage Of similar
composition are almost equal, pound
for pound, as a supplementary feed with
corn
This experiment shows that meat
meal and tankage are profitable adj
juncts to the corn ration for dry lot
feeding when pigs are being developed.
The pigs on pasture ate more of the
concentrated feeds and gained more
rapidly than the pigs eating the same
kind of rations in the dry lots.
The saving effected by the pasture in
the amount of feed required per 100 lbs
of gain was almost inapprecable in the
case of those pigs fed on rations of
corn and meal or corn and tankage in
the proportion of 5 to L.
On the other hand the pigs fed in
the dry lots required for each 100 lbs
of gain produced Is per cent more Of
the ration composed of corn two parts
and shorts equal parts than the pigs
fed similar ration on timothy pasture.
There was less variation in the
amount of protein of the concentrated
feed up to the point where the bal
anced ration fed was to increase
the amount of feed consumed and to
produce correspondingly larger gains.
The cheapest gains in the feeding Of
young pigs were obtained from a ra-
ton of corn alone and clover pasture.
The pigs fed on corn and clover pas
ture made ST per cent as rapid gains
as did those pigs which were fed on
expensive supplementary feeds with corn
on timothy pasture and almost 30 per
cent more rapid gains than did those
pigs on corn alone and timothy pas
ture.
The amount of concentrated feed re-
quired to produce 100 pounds of gain
was nearly as low for the ration of
corn and clover as in the case of anv
of the other rations used either in con-
nection with the pasture or dry lot
feeding.
The gains due to the pasture itself
We're greatest when relatively smaller
amounts of protein were supplied in
the concentrated part of the ration
The ration composed of corn and
clover pasture produced 116 pounds
more pork per acre than the ration
composed of the same number of
pounds of corn and timothy pasture.
A ration of corn alone on timothy
pasture produced the cheapest gains in
weight of any of the rations fed to pigs
on pasture, but the mixed rations pro-
auced the greatest total net profits.
