Comparison of vaginal examination methods to evaluate urovagina and purulent vaginal discharge in periestrous dairy cows.

ABSTRACT: Urovagina and purulent vaginal discharge (PVD) are usually diagnosed using a speculum, Metricheck device, or gloved hand. In periestrous dairy cows, a comparative study of these vaginal examinations for diagnosing urovagina or PVD has not yet been conducted. This study aimed to identify an effective vaginal examination method for periestrous dairy cows to ensure successful artificial insemination. Data were collected from 227 Holstein-Friesian cows during 300 occurrences of spontaneous estrus. Urovagina was evaluated using the speculum and gloved-hand methods and classified as mild, moderate, or severe. Vaginal discharge was evaluated using speculum, Metricheck, and gloved-hand methods and classified as vaginal discharge score (VDS) 0-5, with 2-5 defined as PVD-positive. Sensitivity and sp
