Lecirelin Acetate (CAS 61012-19-9)
A Reliable GnRH Analog for Improved Cattle Reproductive Performance
Lecirelin Acetate is a synthetic analogue of gonadotropin-releasing hormone (GnRH) widely used in veterinary medicine to enhance reproductive efficiency in cattle. By stimulating ovulation and supporting hormonal balance, lecirelin acetate plays an important role in improving fertility outcomes in both dairy and beef production systems.
▸ CAS Number: 61012-19-9
▸ Quality Standard: In-House Standard
▸ Category: Veterinary Hormonal API
Its proven effectiveness and safety profile make lecirelin acetate a trusted solution in modern livestock reproductive management.
Product Overview
Lecirelin Acetate mimics the natural GnRH released by the hypothalamus, triggering the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. These hormones are essential for ovulation and normal reproductive function in cattle.
Key Physicochemical Properties
▸ Molar Mass: 1209.42 g/mol
▸ Density: 1.44
▸ pKa: 9.82 ± 0.15 (predicted)
▸ Appearance: Powder
▸ Color: White to almost white
▸ Storage Conditions: Store in an airtight container
Mechanism of Action
After administration, lecirelin acetate binds to GnRH receptors in the pituitary gland, leading to a controlled release of LH and FSH. This hormonal response:
▸ Induces ovulation
▸ Improves follicular development
▸ Enhances synchronization within breeding programs
▸ Supports consistent reproductive performance
Its targeted action allows precise control over ovulation timing, which is critical in structured breeding and artificial insemination protocols.
Veterinary Applications
Cattle Reproduction Enhancement
Lecirelin acetate is extensively used in dairy and beef cattle to improve reproductive outcomes:
▸ Stimulates ovulation in cycling and non-cycling cows
▸ Increases conception and calving rates
▸ Supports fixed-time artificial insemination (FTAI) programs
▸ Enhances overall herd reproductive efficiency
Safety and Tolerability
▸ Temporary swelling or tenderness at the injection site
▸ Short-term increase in heart rate
▸ Brief reduction in appetite
These effects usually resolve without medical intervention.
Role in Integrated Reproductive Programs
▸ Prostaglandins
▸ Progesterone
▸ Estrogens
The choice of hormone and treatment protocol depends on factors including breed, age, reproductive history, and specific breeding objectives. Lecirelin acetate offers flexibility and compatibility within comprehensive reproductive management strategies.
