Parnell advances cattle health and reproductive performance through proven pharmaceutical solutions and practical herd management support. Our reproductive portfolio, including estroPLAN® and GONAbreed®, helps producers and veterinarians optimize synchronization protocols, improve fertility outcomes, and enhance overall herd productivity.

Through mySYNCH™ Services and Platform, we integrate our reproductive products with data-driven insights, protocol guidance, and hands-on support—enabling teams to make informed decisions and execute breeding programs with confidence and consistency.

Beyond reproduction, RESPIRmycin® delivers dependable treatment for BRD, pinkeye, and hoof rot, supporting overall herd health and operational performance.
