Effect of Removal of Follicular Cyst Content on Success of Ovsynch in Dairy Cows: a Clinical Trial in Private Practice

摘要

Follicular cysts in dairy cows cause abnormal ovarian cyclicity and decrease reproductive performance in dairy herds, particularly in management systems that rely on heat detection. Many treatments have been developed and tested to manage follicular ovarian cysts; among these, ovulation synchronization (GnRH-PGF2-GnRH-Timed AI; Ovsynch) is an option that is easy to implement and gives acceptable results. It has been suggested that removal of cyst content by needle puncture could improve treatment outcome. The purpose of this study was to evaluate the effect of removing cyst content on conception rate in dairy cows treated for follicular cysts with Ovsynch. The trial was conducted using data collected over regular herd health visits in a private practice.
