BETTER 

TOGETHER

Synchsure and Cystorelin together improve reproductive efficiency in cows and heifers.

Together, Cystorelin® (gonadorelin) by Merial and Synchsure (cloprostenol sodium) by Merial should be your go-to combination for reproductive efficiency in cows and heifers.

It’s good to be sure. Take the guesswork out of your cattle breeding program.

Long calving intervals lead to lower lifetime milk production. The primary causes are poor heat detection, waiting too long after calving to begin breeding and low conception rates.1

Help your herd conceive and calve on schedule. When used in combination, CYSTORELIN and SYNCHSURE provide:

  • A missed heat cycle can cost as much as $292
  • A missed pregnancy costs a producer up to $4503
  • Poor reproductive performance and extended lactations steal from your bottom line
  • Shortened time to first service
  • Increased estrus detection efficiency
  • Improved first-service conception rate
Syringe used to administer medication to improve conception rates in cattle.
