Abstract

Thermocouples were placed into the uterine serosa and saphenous artery of four dairy heifers. Injection of Estradiol-17ß (3 mg) caused a 0.25 C decrease (P<.01) in the difference between uterine and aortic temperatures ({bigtriangleup}Tuterus-aorta) by 2.5 hr. post injection. In contrast there was no significant change in the {bigtriangleup}Tuterus-aorta after injection of saline. The Estradiol-17ß induced decrease in {bigtriangleup}Tuterus-aorta could have resulted from an increase in the rate of uterine blood flow.
