EAZI-BREED™ CIDR® Cattle Devices
CIDR™ Cattle Devices contain the natural hormone progesterone.
Intravaginally placed CIDRs release progesterone at a controlled rate
into the blood stream.
- SYNCHRONISATION OF OESTRUS.
- Insert for 7-12 days with injection of prostaglandin
F2α at removal.
- Animals normally come into oestrus 48-96 hours after
- A “heat mount detector” or tail paint for detecting
oestrus is recommended.
- TREATMENT OF POST-PARTUM ANOESTRUS
- When lack of ovarian activity is diagnosed, insert for
5-7 days and inject 1mg oestradiol benzoate 24-48 hours after device
removal. Responsive animals will be detected in oestrus during the next
4 days. Re-examine and then retreat unresponsive animals.
- RESYNCHRONISATION OF OESTRUS
- Insert for 14-17 days after first insemination and
remove on the 21st day post insemination. Animals not pregnant to the
first service are in oestrus approx. 48-96 hours after device removal.
- VETERINARY SPECIALIST USE
- The veterinarian may use the plasma progesterone
elevating properties of the CIDR™ Cattle Device in a program
specifically designed for the requirements of a particular herd. The
device will elevate progesterone blood levels above 1.5 ng/mL for at
least 12 days. This level will drop below 1.5 ng/mL in less than 1 hour
Breeding programs using the CIDR™ Cattle Device can:
- Tighten oestrus synchronization so animals come into
oestrus in a narrow time period
- Provide an opportunity to induce a fertile oestrus in
- Hasten the onset of cyclicity in maiden heifers
- Treat cystic ovarian disease
- Prepare donor recipient cattle for embryo transfer programs.
Using CIDR™ Cattle Devices can result in:
- More pregnancies
- More compact calving season
- More even line of calves
- Less involuntary culling of non-pregnant cows
- Better use of time and labour during breeding, pregnancy
testing and calving
- Tighter calving intervals, with more calves born during a
- Easier and more accurate heat detection, or the option of
no heat detection
- Enhanced use of artificial insemination (AI) or specialist
programs such as ET, with
- Greater genetic gain and higher value calves
- Ability to schedule heifers to calve before older cows, so
heifers can get extra attention
- Easier customised matings – including the use of
calving-ease sires – because AI is more feasible
- Confirmed breeding and calving dates – not always possible
with natural service
- A more profitable herd
- Plastic bags containing 10 devices
- Applicators sold separately.
Dosage and Administration
Refer to the label and manual for appropriate programs
Wear protective gloves when handling the devices.
- Dip the device applicator in a a non-irritating antiseptic
- Place one device into the applicator so the wings are
folded and only the lips of these wings protrude from the front of the
- Dip the front portion of the loaded applicator into a
suitable veterinary obstetrical lubricant
- Lift the tail of the animal and wipe the vulva lips clean
with disposable tissue.
- With the tail lifted, insert the loaded applicator, sloping
slightly upwards, through the vulva and then forward, without forcing,
into the forward portion of the vagina.
- Release the removal tail, grasp the handle of the plunger
and ease back the barrel of the applicator towards the handle.
- With the device correctly placed with the wings opened in
the front portion of the vagina, only the removal tail should be
hanging from the vulva.
- Repeat Step 1 before re-using the applicator
- Withdraw each device by pulling on the removal tail.
- Always remove devices before slaughter.
- Storage: Store in a dry place below 30°C (room temperature).
- Witholding period: * Meat: Nil *Milk: Nil
