Abstract

Endometritis in postpartum dairy cows has been shown to decrease reproductive performance. Endometritis has been classified as clinical (CE; visible purulent discharge on vaginal examination or by measurement of cervical diameter) or subclinical (SCE; inflammation measured with endometrial cytology). Various techniques have been proposed for their diagnosis, including the Metricheck™ (MTCK) device (Simcrotech, New Zealand) and measuring cervical diameter (CERV) by rectal palpation for diagnosing CE, and the cytobrush technique (CYBR) for SCE. It has been assumed that cows with CE are a more severe or evident subset of cows with SCE but little is known about the relationship of CE to SCE. The objectives of this study were to compare the findings of vaginal discharge and cervical diameter with endometrial cytology and to assess the relationship between these results and subsequent reproductive
performance.
