Release time:
2026-08-31
Product Overview
Buserelin Injection is a high-purity, high-activity synthetic gonadotropin-releasing hormone (GnRH) analogue specifically designed for reproductive management in dairy cattle and other livestock. The biological activity of buserelin is approximately 18 to 322 times that of natural GnRH.
Indications (For Cattle)

The primary indications of Buserelin Injection in dairy cows include:
1.Estrus Synchronization in Dairy Cows: Used in combination with prostaglandin analogues for synchronized estrus and timed artificial insemination.
2.Improvement of Pregnancy Rate: Administered at the time of AI or during the luteal phase following AI to significantly enhance pregnancy rates.
3.Treatment of Ovarian Cysts: Including follicular and luteal cysts, with or without symptoms of nymphomania.
4.Treatment of Anovulatory Anoestrus: Used in conjunction with a progesterone device and a PGF₂α analogue.
5.Treatment of Delayed Ovulation: Promotes timely ovulation of mature follicles.
6.Reducing Calving-to-Conception Interval: As part of a 10-day fixed-time insemination regime.

Why Choose Buserelin Injection?

✅ Higher Activity, Lower Dosage
Buserelin Injection utilizes high-purity raw materials and advanced formulation technology, delivering biological activity dozens to hundreds of times that of natural GnRH. Just 20 μg per cow achieves optimal ovulation induction.
✅ Zero Withdrawal, Zero Milk Discard
Buserelin is rapidly metabolized in cattle, with zero withdrawal for meat and zero withdrawal for milk. No milk discard is required post-administration—representing significant economic savings, especially for high-yielding dairy herds.
✅ Scientifically Validated, Clinically Reliable
Multiple clinical trials have confirmed the efficacy of buserelin in dairy cattle estrus synchronization and timed AI programs, with the 20 μg dose group showing significantly higher conception rates than lower-dose groups. Under heat stress conditions, buserelin significantly improves conception rates by enhancing endocrine status and uterine conditions.
✅ Flexible Application, Proven Protocols
Buserelin Injection can be flexibly applied across a wide range of reproductive management protocols—including Ovsynch, Presynch-Ovsynch, Double-Ovsynch, and other mainstream estrus synchronization–timed AI programs.
✅ Quality Assured, Trustworthy
