Gonadorelin for Injection

Precision Oestrus Synchronization & Ovarian Therapy

Gonadorelin for Injection is a specialized hormonal agent designed for the sophisticated management of reproductive cycles in dairy cattle. By stimulating the natural release of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), it serves as the cornerstone for Ovsynch protocols, enabling precise artificial insemination timing and the treatment of ovarian inactivity.

At Origin Biotech, we facilitate global animal health and pharmaceutical innovation through the provision of high-purity bioactive chemicals. This article details the pharmacological profile and optimized administration protocols for Gonadorelin.

Pharmacological Mechanism

Gonadorelin mimics the physiological action of the hypothalamus to regulate the reproductive axis:

  • ▸ Adenohypophysis Stimulation: Triggers the anterior pituitary to release LH and FSH.
  • ▸ Follicular Maturation: Promotes the final maturation of the oocyte and subsequent ovulation in females.
  • ▸ Metabolic Efficiency: Rapidly absorbed and metabolized into inactive fragments, ensuring zero-day withdrawal periods for both meat and milk.

Clinical Indications

  • ▸ Ovarian Inactivity: Treatment of anestrus in dairy cows to restore normal cyclicity.
  • ▸ Estrus Synchronization: Integral component of synchronized breeding programs to improve herd pregnancy rates.

The Ovsynch Protocol

For induction of estrus beginning approximately 50 days postpartum, the following protocol is recommended:

Day 0: Gonadorelin Injection (100–200 μg/head)
Day 7: Cloprostenol Sodium Injection (0.5 mg)
Day 9: Second Gonadorelin Injection (100–200 μg/head)
Hour 18–20: Perform Fixed-Time Artificial Insemination (AI)

Safety & Precautions

  • Zero Withdrawal: No withdrawal period is required for meat or milk in cattle.
  • Usage Restriction: Prohibited for use as a growth promoter.
  • Drug Interaction: Avoid concurrent use with other hormonal agents unless specified by the protocol.
  • Storage: Keep in sealed, cool, and dark conditions (<20°C).
