Keeping your herd healthy pays off in reproduction, and in a big way. In fact, each missed pregnancy can cost a producer up to $450.1 That’s a big drain on your bottom line. Count on CYSTORELIN® (gonadorelin diacetate tetrahydrate) to help your herd conceive and calve on schedule.

  • It’s the first and number one selling2 GnRH product approved by the FDA for treatment of cystic ovaries in cattle.
  • CYSTORELIN treats ovarian follicular cysts, which affect an estimated one million cows annually2 and can leave cows infertile as long as the condition persists.
  • In two studies, CYSTORELIN induced ovulation in an average of 95% of cows.3
  • By treating for ovarian follicular cysts, CYSTORELIN activates the process leading to estrus.
  • Available in a 10-bottle carton with 15 doses per bottle. That gives you more doses in one bottle than any other GnRH. We also offer the flexibility of a 5-dose bottle.
  • Easy to use with no milk withholding and no meat withdrawal.

IMPORTANT SAFETY INFORMATION: DO NOT USE IN HUMANS. KEEP THIS AND ALL DRUGS OUT OF THE REACH OF CHILDREN.
