Efficiency matters when it comes to dairy and beef cattle reproduction. Merck Animal Health’s reproductive lineup includes a host of products that can help increase performance and control.

This cloprostenol brings the heat – and then some.

ESTRUMATE injection for cattle is the top cloprostenol on the market, proven to improve reproductive performance in both dairy and beef cattle.1 This essential reproductive tool allows for better heat detection and increased control of breeding and calving intervals.

ESTRUMATE can also be used with FERTAGYL® (gonadorelin) GnRH to synchronize estrous cycles to allow for fixed-time AI.

The GnRH that makes fertility simple.

FERTAGYL for cattle improves reproductive efficiency by synchronizing estrous cycles as well as treating cystic ovaries. Research has shown that FERTAGYL produces both high ovulation and pregnancy rates.2,3 To maximize reproductive efficiency, choose a program that includes FERTAGYL and ESTRUMATE used together.

ESTRUMATE IMPORTANT SAFETY INFORMATION: Women of childbearing age, asthmatics, and persons with respiratory problems should exercise extreme caution when handling ESTRUMATE. ESTRUMATE is readily absorbed through the skin and may cause abortion and/or bronchospasms; direct contact with the skin should be avoided and accidental spillage on the skin should be washed off immediately with soap and water. Do not administer ESTRUMATE to a pregnant cow if abortion is not desired. Severe localized post-injection clostridial infections have been reported; in rare instances infection has led to death. At 50 and 100 times the recommended dose, mild side effects may be detected. For complete information on ESTRUMATE, see package insert.
