Targeted reproductive support for cattle fertility Product Description CYSTORELIN® is an FDA-approved injectable reproductive solution for beef and dairy cattle designed to support the treatment of ovarian follicular cysts and help synchronize estrous cycles for fixed time artificial insemination (FTAI). It contains gonadorelin to promote natural hormone release that supports ovulation and reproductive timing. This makes it useful as part of herd fertility management under veterinary guidance. Benefits Ovarian cyst treatment: Helps resolve non-ovulated follicles to encourage normal reproductive cycles in dairy cattle. Estrous synchronization: Works with cloprostenol sodium to align heat cycles for reliable breeding timing. Injection flexibility: Can be given intramuscularly or intravenously based on veterinarian instructions. Veterinary trusted: FDA approval and long-standing use in reproductive protocols make it a dependable choice. No milk or meat withdrawal: When used as directed, cows do not require milk discard or meat withholding periods.
