Aaron: Ionophores are a nutritional biotechnology
used commercially in beef cattle
and poultry with limited use in
lactating dairy cattle diets
Ionophores are commonly fair to all classes
of beef cattle
resulting in increased feed efficiency and
improved average daily gains
They are commonly fair to broilers,
broiler breeders, and
replacement pollets to
control the diesase, coccidiosis
Examples of Ionophores used in the beef cattle
industry include Menoshin, marketed under the trade
name: Rumensin
Lasalasin, marketed under the trade name: Bovatec
and Lalamonsin,
marketed under the trade name: Cattlyst
Ionophones are classified as a polyether antibiotic
in that they cause a shift in the rhema microorganism
populations
This shift in microbia population affects
how feeds are fermented and creates a decrease in
acetate production and an increase in
propionate production
Both are volatile fatty acids
produced through rumen fermentation
which along with butyrate are used
as a primary source of energy
for the ruminant animal
Farm animals that are considered ruminants include
beef and dairy cattle, sheep, and goats
This increase in beneficial bacteria and protozoa
through the use of an ionophore
decreases the loss of energy through the
production of methane gas
and carbon dioxide
during rumen fermentation
Methane is a greenhouse gas
that along with carbon dioxide
are waste products of rumen fermentation
that represent an inefficiency of that fermentation
the addition of ionophores increases the efficiency
of the use of ingested feed
Thus increasing the overall energy status
of the animal
which leads to increased weight gain and
stalker and backgrounder cattle
and a reduction in the amount of feed required
per unit of gain in feed lock cattle
There is also a decrease in the incidents
of bloat and acidosis
in ionophores fed cattle
Both of which inhabitant feed intake
Additionally,
ionophores are used to reduce the incidents
of coccidiosis
Which is a diarrheal condition
caused by protozoa parasites
that can have a negative impact
on animal performance
An added benefit of the use of ionophores
is that they are a completely different
class of compounds
and will not contribute to antibiotic resistance in humans
Today, we're going to talk a little about the ionophores
and the ionophores are a polyether antibiotic
Uh that causes a shift in the ruma microbial population
and basically makes the animal more
energetically efficient
uh, now we talked about polyether antibiotics
and it can be confused with
antibiotics that we might use
in human medicine
um
And cause bacterial resistance
This a completely different class of compounds
uh that uh there is no antibiotic in the human world
that uh that looks like this
and so
we don't have to be concerned about this uh
bacterial resistance problem
The reason why we use ionphores is to increase
weight gain in cattle that are on a high forage diet
In cattle on a high energy diet
will respond a little differently
by increasing feed efficiency
And, the net result of that is is that we will reduce
some of the carbon emissions like in methane
or carbon dioxide simply because we make the
rumen much more efficent
and causing the shift in microbial population
and increasing the volatile fatty acid
called propranate
Uh one of the side benefits of using ionophores is
that it does help control coccidiosis
which is a parasite
uh challenge on the animal
And another benefit would be reduction in bulge
uh which could be important to some of our
feeder steers and some of our 4-H calves
The other part of the
benefit is I think of the ionophores
is that it helps stabilize
feed intake
uh making the cattle a little bit more
of a snack eater
instead of a big meal eater
And, that then helps reduce
the amount of uh potential asidosis
or the lowering of ph of a rumen
on a high concentrate diet
Ionophores are a nutritional biotechnology
that shift rumen microorganism populations causing
an increase in the efficiency of rumen fermentation
by decreasing the losses associated with methane
and carbon dioxide
This increases feed efficiency and performance in
beef cattle
Additionally, ionophores are used to control coccidiosis
in beef cattle and poultry diets
Even though, they are considered
an antibiotic, they are completely seperate
from those used in human medicine
And, do not contribute to antibiotic resistance issues
