Experiments With Cornfed Hogs Show
Which Proportions Get Best Carcass
More and more Ontario farmers
are feeding corn to pigs. They like
it as a source of cheap, easily
digestible energy. But corn has one
big short coming: when overfed, it
produces a fatty carcass.
Farmers who self -feed corn and
concentrate, run into this problem
constantly., A pig slows down in
growth after reaching 110 pounds,
and tends to put extra energy into
fat instead of meat.
Animal husbandry experts at the
Ontario Agricultural College are
working on this problem. They
are carrying out tests to find out
what levels of corn should be fed
at the different hog weights. The
researchers also are trying to find
out how much protein should be
fed with corn and what level of

low-energy oats is needed to cut
down the "strength" of corn.
In one experiment, two ratios
of corn to oats were fed to grow-
ing pigs, and three ratios of corn
to oats were fed to hogs from 125
pounds to market weight. Pigs
were also divided into two groups
according to their level of protein.
The higher protein level was 17
percent protein to pigs up to 75
pounds; 15 percent protein from 75
to 125 pounds; and 13 percent to
hogs between 125 and 200 pounds.
The lower protein level was 14 per -
sent to 75 pounds; 12 percent from
75 to 125 pounds and 10 percent
from 125 to 200 pounds. Here are
the results:
Pigs on high protein gained 1/10
pound faster -1.62 pounds per day
compared to 1.52 pounds per day—

Liquid Fertilizer Shows Results
available Potassium (K20) per 100,
pounds of liquid. That's the same•
amount of plant food per 100
I pounds of 5-10-10 dry fertilizer,"
But Costs Must Be considered 1
A relatively new kind of plant
food --liquid fertilizer sold by the
ton (not by the gallon)—proved as
good as the dry product in recent
tests at the Ontario Agricultural
College.
Soil scientist, Dr. J. W. Ketch-
eson found no difference in com-
parisons between pumped in liquid
fertilizer and dry fertilizer that
was drilled with the seed. Inone
comparison, 200 pounds per acre
applied with the seed of Clinton
Oats, and 200 pounds of dry 5-10-
10 fertilizer was drilled in the
usual way. "The same yield of oats
was produced", notes Dr. Ketch-
eson. "An increase of seven bush-
els of oats resulted from the dry
fertilizer and from the liquid fer-
tilizer treatment on adjacent
plots".
"Liquid fertilizer has one ad-
vantage over dry fertilizer in that
the liquid can be pumped—there
are no bags of fertilizer to hand-
le", he adds. "On the other hand,
tanks and pumps are needed to
handle liquid fertilizer, while dry
fertilizers can be used with an or-
dinary fertilizer drill."

Some farmers pump the liquid'
into the soil through weed spray-
ing equipment mounted on the
corn planter. Others buy special
tanks, run tubes down by the shoe
of their corn planter, and inject
the liquid that way.
Dr. Ketcheson stresses that far-
mers who live in areas serviced in
bulk liquid fertilizer should con-
sider the cost per ton before buy-
ing liquids. "Take into account
transportation costs, application
costs, and price per pound of act-
ive plant food. A 5-10-10 liquid
fertilizer, for example, contains
5 pounds of available nitrogen
(N), 10 pounds of available phos-
phorus (P205) and 10 pounds of
than pigs on low protein. The high
protein pigs also cost less to feed
and produced better carcasses than
pigs on low protein feeding. The
corn; oat ratio studies showed
"there was some benefit from in-
cluding high levels of corn in the
rations of pigs up to 125 pounds".
The experiments are continuing.

Field Crops Dept.
I rges Control
Of Yellow Rocket
Yellow Rocket, a primary nox-
ious weed, continues to spread in
Ontario despite efforts to control
it, states the Field Crops Branch
of the Ontario Department of Ag-
riculture.
Sometimes called Winter Cress,
Yellow Rocket is often mistaken
for Wild Mustard. However, it is
easy to distinguish between them.
Yellow Rocket usually flowers in
the middle of May and Wild Must-
ard three weeks later. Yellow Ro-
cket has a number of main roots,
while Wild Mustard has a single
tap root. Yellow Rocket is a
smooth plant with shiny lobed
leaves; Mustard is quite hairy with
sharply margined, dull -colored lea-
ves.
The use of high-grade seed is
one way of preventing new infest-
ations; for example, not one seed
of Yellow Rocket may be present
in No. 1 Grade Clover seed. Sin-
gle plants of Yellow Rocket should
be pulled and burned. Plants in
pastures should be mowed when
flowers appear. Fields that are
polluted with this weed should be
out early for grass silage when-
ever possible. Seeds that ripen will
be destroyed by fermentation in
the silo. Good drainage and thor-
ough spring and fall cultivation
help kill Yellow Rocket.
Yellow Rocket may be controll-
ed in mature stands of Alfalfa by
applying 6 ounces of M.C.P. amine
acid in 50 gallons of water per acre
after the tops of the Alfalfa have
been killed by fall frosts. Daytime
temperatures should be above 45
degree F. when spray is applied.
The Alfalfa tops are usually dor-
mant, and the daytime temperat-
ure right, during the last week in
October or first week in Novemb-
er.
It takes time and effort to erad-
icate Yellow Rocket, but there is
a great deal of satisfaction in see-
ing a clean field.

UREA waits in the soil
to feed your corn!
Now, there's an economical new way to give
your corn the nitrogen you know it needs
to make a full profitable crop. The secret—
pllowdown or preplant with new AERO*
UREA.
This 45% nitrogen fertilizer is ideal for corn.
It acts quickly to get the crop started, yet stays
in the soil for release to the crop when it
needs food most.
Use Aero Urea these two ways:
Spring or Fall Plowdown: Broadcast 100-200
pounds of Aero Urea per acre before plowing.
Preplant: Broadcast 100-200 pounds
of Aero Urea before last cultivation.
Then work into the soil and plant.
