The Economic Advantages of Using Insecticide Ear Tags |
Flies
Are Taking Huge Bites Out of Your Profits!
Sustained infestation of more than 100 horn flies per animal can
cause large economic losses. Cattle fight flies instead of grazing
which interferes with feed intake. Bulls may be hindered from
breeding. Cows may lose weight while lactating. Milk production
and calf weaning weights may be reduced.
- Horn flies
cost U.S. cattle producers $876 million annually.
- Fly infestations
cost U.S. beef and dairy cattle producers over $1.6* billion annually.

I. The Importance Of Fly Control
By controlling
flies on cattle, many economic benefits can be obtained:* More
pounds of meat produced
- More pounds
of milk produced
- Better conception
rates
- Reduced incidence
of pink eye
- Greater producer
returns
The Horn
Fly
The
horn fly is a major pest of pastured cattle. This small, gray
fly resides on domestic cattle day and night during the fly season.
It is found on the neck, shoulders, back and side. The horn fly’s
life cycle is completed in 12 - 20 days. It reproduces by laying
its eggs in fresh manure. Horn flies are very stressful to cattle
as they take between 24 to 38 blood meals daily. As many as 2,000
to 5,000 flies can feed daily on a single animal causing blood
loss, weight loss and irritation.
The Face Fly
Face flies irritate the eyes, causing stress and extreme annoyance
to cattle. This stress may reduce feed intake resulting in poor
performance. Face flies have also been implicated in the transmission
of IBR and the organism that causes pink eye, Moraxella bovis.
Methods of Control
Sprays and Dips Disadvantages ----- Erratic fly control
-
Container disposal
-
Frequent
re-treatment required
-
Frequent rounding up for treating causes animal stress and weight
loss
-
Withholding
periods may be required to eliminate residues
Back
rubbers and dust bags Disadvantages ----- Erratic fly control
Y-TEX
Insecticide Ear Tags

Insecticide chemistries need to be rotated, however, excellent
rotation programs exist for tags versus other pest
control methods

Insecticide
Rotation Is Important!!!
-
It
relieves the horn fly population of resistant-fly selection
pressure from the same type of insecticide.
-
Pyrethroid-resistant horn flies tend to have enhanced susceptibility
to organophosphate insecticides.
-
Horn fly resistance to one insecticide class tends to drop while
the other insecticide class is in use.
-
Extra
treatment time is given with organophosphates, due to their
slower rate of resistance development compared with pyrethroids.
As
resistance to a given insecticide class increases, horn fly control
will decline. Here is an example of how pyrethroid insecticide
tag performance is affected as pyrethroid insecticide resistance
increases---

|
|
By
rotating insecticide tags, horn fly resistance to one insecticide
class tends to drop while the other insecticide class is in use.
Here is an example of how pyrethroid resistance changes when cattle
are tagged with either pyrethroid or organophosphate insecticide
tags:

In
the previous example, when the pyrethroid tags, PYthon and Saber
Extra were used, pyrethroid resistance increased. When the organophosphate
tags were used, pyrethroid resistance declined.
The Y-TEX Insecticide Tag Rotation Program

Y-TEX Insecticide Tags and tag rotation provide excellent return
on every dollar invested. Using Y-TEX® PYthon™ Insecticide
Ear Tags to control horn flies on cow-calf pairs pays big DIVIDENDS:
|
Weight
Gain Advantage Using PYthon
1.
120 day study conducted in Tennessee in 1997.
2. Calves of both treated and untreated groups were castrated,
vaccinated and implanted.
3. Saber Extra and Double Barrell are trademarks of Mallinkrodt
Veterinary Div., Schering Plough.
4. Cutter Gold is a trademark of Bayer Corporation.
The additional weight gain of 69.60 pounds per calf in
the first PYthon treated herd amounts to $48.74 more value
per calf, @$.70 per pound selling price, over calves in the
untreated herd. The additional weight gain of 40.80 pounds
per calf in the second PYthon treated herd amounts to $28.56
more value per calf.

Y-TEX®
WARRIOR™ Insecticide Ear Tags control horn flies and offer
an excellent return per dollar invested!

WARRIOR
Weight Gain Advantages
1.
Study conducted in Louisiana in 1997 for 89 days.
2. Replacement heifers were used for this study.
3. Additional returns from treatment would be expected in the
form of enhanced conception rates.
The additional weight gain of 51.8 pounds per animal in
the WARRIOR treated herd amounts to $36.26 more value per heifer,
@$.70 per pound selling price, over heifers in the untreated herd.
Y-TEX PYthon Insecticide Tags
PYthon is the only cattle product to contain zeta-cypermethrin,
a powerful pyrethroid insecticide. Its synergized formulation
has excellent activity against many pests including horn flies
resistant to other insecticides.
PYthon is labeled for use on beef and dairy cattle, including
calves and lactating dairy cows. It controls horn flies 3 to 4
months with one tag per head and up to 5 months with two tags
per head when used in an insecticide rotation program. PYthon
controls face flies, lice, Gulf Coast ticks, and spinose ear ticks
for up to 5 months with two tags per head and aids in control
of face flies with one tag per head requiring no withdrawal time.
PYthon features the Y-TEX patented Snap-Lok™ collar for 5
months guaranteed retention against tag or button failure.
Y-TEX WARRIOR™ Insecticide Tags
WARRIOR is a unique 40% organophosphate ear tag which releases
a synergized formulation of diazinon and chlorpyrifos. This patented
formula exhibits greater potency than either insecticide used
alone and is especially effective against pyrethroid-resistant
pests.
WARRIOR is approved for use on beef and non-lactating dairy
cattle. It controls horn flies and aids in control of face flies
for 3 to 4 months with one tag per head and up to 5 months at
two tags per head. When WARRIOR is used in an insecticide rotation
program it controls lice, Gulf Coast and spinose ear ticks up
to 5 months and aids in control of stable flies and house flies
with two tags per head requiring no withdrawal time. WARRIOR also
features the Y-TEX patented Snap-Lok™ collar for guaranteed
retention against tag or button loss for 5 months.
The Y-TEX PYthon and WARRIOR Insecticide Ear Tag rotation program
makes DOLLARS and SENSE!
