Fertagyl (gonadorelin) Injection for Cattle

Reliable Estrous Synchronization for Dairy and Beef Cattle

Product Description

Fertagyl is a sterile gonadorelin injection formulated to treat ovarian follicular cysts in dairy cattle and support estrous synchronization programs in both dairy and beef cows. By promoting the release of luteinizing hormone, it promotes ovulation and improves fixed-time artificial insemination outcomes. It is veterinarian-restricted and requires no milk discard or withdrawal period when used as directed.

Benefits

• Induces Ovulation: Stimulates endogenous luteinizing hormone release to promote ovulation and luteinization in cattle.
• Treats Cystic Ovaries: Effectively manages ovarian follicular cysts associated with irregular estrus in dairy cattle.
• Improves Pregnancy Rates: Demonstrated significantly higher pregnancy rates in fixed-time artificial insemination field studies.
• Supports FTAI Programs: Designed for use with cloprostenol products to synchronize estrous cycles in dairy and beef cows.
• No Withdrawal Required: No milk discard time or meat withdrawal period when used according to label directions.
• Proven Safety Margin: Established safety through toxicology studies and field evaluations with no significant health abnormalities observed.

Frequently Asked Questions

Q1: What is Fertagyl used for in cattle?

Ans: Fertagyl is indicated for the treatment of ovarian follicular cysts in dairy cattle and for use with cloprostenol products to synchronize estrous cycles for fixed time artificial insemination in dairy and beef cows. It stimulates endogenous luteinizing hormone release to promote ovulation and luteinization.

Q2: How does Fertagyl work in cows?

Ans: Fertagyl is formulated with gonadorelin, a synthetic version of the natural GnRH hormone found in cattle. After administration, it acts on the anterior pituitary gland to release key reproductive hormone and follicle stimulating hormone. This process leads to ovulation and plays an important role in planned reproductive management programs.

Q3: What is the recommended dosage of Fertagyl?

Ans: The recommended dose is 86 mcg gonadorelin, equivalent to 2 mL per cow. It may be administered intramuscularly or intravenously for cystic ovaries and intramuscularly as part of estrous synchronization protocols in dairy and beef cattle.

Q4: Is there a milk withdrawal or meat withdrawal period for Fertagyl?

Ans: When used according to label directions, Fertagyl does not require a milk discard time or a meat withdrawal period. This makes it suitable for use in lactating dairy cows within approved reproductive management programs.

Q5: Is Fertagyl safe for cattle?

Ans: Safety has been demonstrated through toxicology studies and field trials. The incidence of health abnormalities was not significantly greater than that of placebo-treated cattle, and no significant injection site reactions were observed during effectiveness studies in dairy and beef cows.
