Ipsilateral uterine artery cross-sectional area (CSA; A) and blood flow (BF; B) and contralateral uterine artery CSA (C) and BF (D) of beef cows fed the control (control group [CON]) or the control plus supplement (treatment group [SUP]) from d 201 to 270 of gestation. a–eLeast squares means ± SEM with different superscripts differ at P ≤ 0.05. Trt = treatment.

Total uterine blood flow (A) and maternal heart rate (B) of beef cows fed the control (control group [CON]) or the control plus supplement (treatment group [SUP]) from d 201 to 270 of gestation. a–cLeast squares means ± SEM with different superscripts differ at P ≤ 0.05. Trt = treatment; bpm = beats per minute.

Ipsilateral and contralateral uterine artery pulsatility index of beef cows fed the control or the control plus supplement from d 201 to 270 of gestation. a–c, x–zLeast squares means ± SEM within artery with different superscripts differ at P ≤ 0.05. Trt = treatment.
