Introduction

The University of Arizona hosts several Artificial Insemination (A.I.) clinics for cattle producers each year. One of the most common points of confusion for producers navigating the A.I. process is understanding estrus synchronization and determining which products are equivalent to each other across manufacturers. This fact sheet is provided as a guide to help identify equivalent
estrus synchronization products across major brands, it is not intended to promote any specific brand or product. The University of Arizona does not endorse any specific product and 
recommends users do their own research and work with their veterinarian to determine which products are appropriate for them and their operation.
