title: The effect of pregnancy and foaling on intravaginal pressure in pony mares.
abstract: Pressures were recorded monthly at two sites in the vagina of each of five pregnant and five nonpregnant pony mares; pressures in five mares were also recorded weekly after foaling. The developing pregnancy did not influence pressure, and after foaling the integrity of the seal formed by the caudal reproductive tract was rapidly restored.
