CIDR® Devices (Cattle)
Eazi-Breed CIDR Cattle Devices contain the natural hormone progesterone. Intra-vaginally placed CIDR’s release progesterone at a controlled rate into the blood stream.
Recommendations for use
- Synchronisation of Oestrus
- Insert for 7-12 days with injection of prostaglandin F2α at removal.
- Animals normally come into oestrus 48-96 hours after removal.
- A “heat mount detector” or tail paint for detecting oestrus is recommended.
- In lactating dairy cows, when lack of ovarian activity is diagnosed, CIDR is used in conjunction with GnRH and Lutalyse®
- In beef cows, when lack of ovarian activity is diagnosed, insert for 5-7 days and inject 1 mg 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.
- 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.
- 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 1.5ng/mL for at least 12 days.
- This level will drop below 1.5ng/mL in less than 1 hour after removal.
The Zoetis Advantage
Breeding programs using the CIDR Cattle Device can:
- Tighten oestrus synchronisation so animals come into oestrus in a narrow time period
- Provide an opportunity to induce a fertile oestrus in non-cycling cows
- 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 cow’s lifetime
- 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.
Wear protective gloves when handling the devices.
- Dip the device applicator in a non-irritating antiseptic solution.
- Place one device into the applicator so the wings are folded and only the tips of these wings protrude from the front of the applicator.
- 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 at least 24 hours before slaughter.
