Urea may lead to profits or death
Summer is past history
and Fall is well upon us.
There are two very critical
jobs to be accomplished
during these transition
months between the growing
season of Summer and the
feeding season of Winter.
One task is the culmination
of the harvest which started
in early Spring with Winter
rye, proceeded through the
Summer with small grams
and hay, silage harvest of
early Fall, and finally the
com grain and soybeans
before the snow starts to fly.
The other task occurs as the
farmer stands back, takes
stock of the feed he has been
able to produce himself, and
decides what is going to be
necessary to purchase to
supplement his home grown
feeds.
The largest cash outlay for
purchased feed is by far
protein, and this is the area
farmers most often look to
when cutting comers or
cutting costs. However, the
management decisions as to
whether to substitute non
protem-mtrogen (NPN)
sources for vegetable

protein requires a com
pletely different line of
thought than it did a few
years ago. In the “good ole
days” (and this was not too
many years ago) urea was
cheap and could always be
substituted for vegetable
protein at a substantial
savings. Now with the in
creased cost of urea and the
rollercoaster prices of
vegetable protein, one must
use his calculator to decide if
substitution of a NPN source
is economical at any one
particular tune, and this
may change several times
during a year.
Protein is made up of
smaller units called ammo
acids which in turn are made
up of several elements in
cluding nitrogen, which is
essential. Most animal’s
requirement of protein must
be satisfied by ingesting the
intact protein or amino
acids. It was discovered in
1891 that the bacteria and
protozoa of the rumen can
use non-protein nitrogen for
the formation of protein. As
the rumen microorganisms

multiply they manufacture
their own body protein,
mostly from the raw
material of the ration
ingested. This bacterial and
protozoal protem may then
be digested in the stomach
and intestine of the ruminant
host. So bacteria can take
nitrogen from a non protein
source such as urea, com
bine it with certain car
bohydrates to form protein,
which is then available to the
host animal. Early research
resulted in usage of non
protem sources of nitrogen
in the livestock industry
starting during World War
11. The question of whether
or not to feed urea or other
non protein nitrogen source
as a subsitute for some of
the natural vegetable
protein must be made on
more than just economic
considerations. There are
many who would never feed
urea and feel that urea itself
is harmful and can cause
problems.
The facts are that urea
can be a cheaper substitute
for protein rich feeds or sup
plements (depending on the
prevailing prices) for any

animal with an actively
functioning rumen, ex
cluding young calves but
including cattle, sheep,
goats, camels, deer,
giraffes, and buffalo.
However extreme care must
be exercised to successfully
feed non protem nitrogen.
When feeding NPN you are
substituting a simple syn
thetic nitrogen containing
compound for some natural
vegetable protein which also
contains vitamins, minerals,
carbohydrates etc. Such a
NPN ration should thus be
suitably fortified to insure
adequate phosphorus, trace
minerals, sulfur and soluble
carbohydrates (starches and
sugars) so as to provide the
rumen organisms adequate
buidlmg blocks to combine
with the nitrogen to make
the protein.
Urea must be fed only to a
limited degree, most figures
being given at about three
per cent of the concentrate.
Since rumen organisms
must adjust gradually to
urea feeds, introduction
should be gradual, usually
three to four weeks being
adequate.
