Biorelin Injection is an injectable Gonadotrophin Releasing Hormone (GnRH) analogue for the induction of ovulation in the mare.
This product is indicated for inducing ovulation within 48 hours in oestrous mares with an ovarian follicle greater than 30mm in diameter
Biorelin Injection (deslorelin) is a synthetic Gonadatrophin Releasing Hormone (GnRH) for induction and timing of ovulation inoestrual mares.
The long duration of oestrus in mares, and the varying time from the onset of oestrus to ovulation, typically results in the need for multiple breedings or inseminations in order to achieve conception. Biorelin Injection induces ovulation within 48 hours after treatment in oestrous mares with a developing follicle greater than 30mm in diameter by increasing the levels of endogenous luteinizing hormone (LH).
Biorelin Injection is a sustained release, non-aqueous formulation and is indicated for the induction of ovulation in oestrous mares with an ovarian follicle greater than 30 mm in diameter.
It is intended to optimise breeding management by shortening the oestrous period, thereby allowing for stallions and assisted breeding programs to be more efficiently managed.
Following the use of Biorelin, the length of the inter-ovulatory interval between cycles is not altered.
The pregnancy rate of mares treated with Biorelin is similar to that of control mares.
Adverse Reactions In a clinical trial conducted in Australia injection site reactions were observed in 15.6% of treated mares. The reactions were mild to moderate swellings at the injection site which may be painful on palpation. These reactions typically resolve within 36 hours.
