Boehringer Ingelheim Provides Cattle Producers with More Reproductive Flexibility

Larger bottle sizes of Cystorelin® (gonadorelin) are now available


DULUTH, Ga. (Feb. 6, 2020) — Better reproductive performance leads to better profit performance. Research has shown that estrous synchronization can improve breeding efficiency, increase pregnancy rates and shorten the calving interval.1

To provide producers with more flexible administration options, Boehringer Ingelheim has introduced a new 100-mL bottle of Cystorelin® (gonadorelin). This larger packaging allows producers to treat up to 50 cows per bottle, compared to just 15 doses with the 30-mL bottle.

“CYSTORELIN and Synchsure® (cloprostenol sodium) offer dependability and flexibility that can improve overall herd reproductive performance,” said Barbara Petersen, DVM, marketing manager, Boehringer Ingelheim. “We’re excited to provide producers with a larger bottle size of CYSTORELIN, to complement the 100-milliliter SYNCHSURE bottle already offered, for added convenience.”

By using Boehringer Ingelheim’s trusted products, SYNCHSURE and CYSTORELIN, cattle producers can take the guesswork out of their breeding program. When used together, these products provide a shortened time to first service, increased estrus detection efficiency, and improved first-service conception rates.
