The goal of this study was to determine the effects of the length of the preovulatory phase on genital blood flow and mRNA expression of endometrial hormone receptors in cattle (Bos Taurus). Ovulation was synchronized in 50 Holstein-Friesian cows using a modified Ovsynch (ovulation synchronization) protocol, in which the second gonadotropin-releasing hormone (GnRH) administration was given 40h (G40, n=17) or 60h (G60, n=16) after the prostaglandin F(2alpha) (PGF(2alpha)) administration.
