Chronogest CR Data Sheet
Presentation
White cylindrical polyester polyurethane foam equipped with string.
Each polyester polyurethane sponge contains 20mg flugestone acetate.
Uses
In ewes and ewe-lambs, in combination with PMSG (Pregnant Mare Serum Gonadotrophin).
- Induction and synchronisation of oestrus and ovulation (non-cycling ewes during seasonal anoestrus ewe-lambs).
- Synchronisation of oestrus and ovulation (cycling ewes and ewe-lambs).
Dosage and administration
The dose is one sponge per animal irrespective of body weight, breed, type (dairy or meat) and season.
The sponge is inserted intra-vaginally using an applicator.
Duration of sponge residence is 14 days. At the end of the administration period, the sponge is gently removed by pulling on its string.
To obtain an optimal synchronisation of ovulation, an injection of PMSG (range 300-700 IU) is recommended (i.m.) at the time of sponge removal.
In case fixed time artificial insemination is applied, it is recommended to perform it 55 h after sponge removal.
Contra-indications, warnings, etc.
Do not use in pregnant females.
A muco-purulent discharge may occasionally be observed at sponge removal. It is not associated with clinical signs and does not alter fertility.
Repeated treatment with the product combined with PMSG may trigger the appearance of PMSG antibodies in some ewes. This in turn may affect the time of ovulation and result in reduced fertility when combined with fixed time artificial insemination at 55 hrs. following sponge removal.
The repeated use of sponges within one year has not been studied.
The use of a vaginal applicator designed for ewes or ewe-lambs is recommended to insert the sponges correctly and to avoid vaginal injuries.
The sponges should not be used in conjunction with alcohols, cresols, phenols, sheep dips or similar disinfectants.
Withdrawal periods:
For meat: 2 days after withdrawal of sponges.
For milk: zero days, including the treatment period.
