-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
The product can be used during lactation.
The use is not recommended during gestation.
The sponges should not be used in conjunction with alcohols, cresols, phenols, sheep dips or similar disinfectants.
The 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 h 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 correctly insert sponges and to avoid vaginal injuries.
For meat: 2 days after withdrawal of sponges.
For milk: zero hours, including the treatment time.
