Abstract

A previous study demonstrated that the doppler ultrasonography could be used to identify cows not pregnant 20 days after last insemination (DALI). Unfortunately, such study was not repeated and it remains unclear if this diagnostic tool could also be used 21 DALI. Therefore, the objective of this study was to quantify the accuracy of using Doppler ultrasonography to diagnose nonpregnancy (NPG) in lactating dairy cows 21 DALI.
