Automatic and manual Doppler velocimetry measurements of the uterine artery in pregnant ewes.

•Doppler velocimetry measurements obtained automatically and manually may differ.•Hemodynamic indices and parameters of blood flow velocity of the uterine artery are scarce in sheep.•Knowledge of uterine perfusion may prevent reproductive failures and increase economic gain.•Doppler application in reproduction should be routinely used in sheep gynecology.
