Abstract

Abstract: This study investigated a preliminary assessment of the vulvar angle measurement in mare using the Angle meter mobile application, as a potential alternative to the conventional vulvometer, the current standard method. Thirty warmblood mares, aged 5 to 9 years, were used in this study. Vulvar angles were measured using a vulvometer placed directly on the vulva and compared to the measurements obtained from photographs using the Angle meter application. The results showed that the mean vulvar angle measured by the vulvometer was 26.30±5.91 degrees, while the Angle meter application produced a mean angle of 25.70±4.71 degrees. A paired t-test showed no statistically significant difference between the two measurement methods. These findings suggest the Angle Meter application is a convenient, quick, and practical alternative for vulvar angle assessment in the field or horse breeding farms.
