title: The effect of weight on intravaginal pressure and vulval conformation of mares.
abstract: Pressures were recorded monthly at two sites in the vaginas of nine horse mares with normal vulval conformation. The pressures were lowest when the mares' weights were minimal, and there was evidence of a descending pressure gradient from the vestibule to the cervix. Loss of body weight was also associated with shortening and angulation of the vulva, although it was not displaced above the pelvic brim.
