Product Description

CYSTORELIN is indicated for the treatment of ovarian follicular cysts in dairy cattle. Ovarian cysts are non-ovulated follicles with incomplete luteinization which result in nymphomania or irregular estrus. Historically, cystic ovaries have responded to an exogenous source of luteinizing hormone (LH) such as human chorionic gonadotropin. CYSTORELIN initiates release of endogenous LH to cause ovulation and luteinization.

CYSTORELIN was the first-selling GnRH productapproved by the FDA for treatment of cystic ovaries in cattle. CYSTORELIN is labeled for use in combination with SYNCHSURE to synchronize estrous cycles to allow for fixed-time artificial insemination (FTAI) in lactating dairy cows and beef cows.

Top Reasons for using CYSTORELIN and SYNCHSURE in a Synchronization Program

1) CYSTORELIN and SYNCHSURE should be the go-to combination for reproductive efficiency in cows and heifers.

  • Efficient reproduction is vital to the success of any operation, so it’s not something that should be left to chance. CYSTORELIN and SYNCHSURE can help you take the guesswork out of herd management to meet your reproduction goals.

2) Help your herd conceive and calve on schedule.

  • When used in combination, CYSTORELIN and SYNCHSURE can provide:
    • Shortened time to first service
    • Increased estrus detection efficiency
    • Improved first-service conception rate

3) Reduce your days open and save money.

  • A missed heat cycle can cost $29, and a missed pregnancy can cost
    $450.2,3 Don’t let poor reproductive performance and extended lactations steal from your bottom line. Proper use of CYSTORELIN and SYNCHSURE can increase your herd pregnancy rate, therefore reducing your days open to save you money.

4) Customized syringes.

  • Customized syringes are available for CYSTORELIN and SYNCHSURE with their respective product logos to allow for ease of administration and to prevent confusion of products.

5) Flexible and easy to use.
