title: Dose of progesterone and allantoic fluid volume in conceptuses in ovariectomised goats.
abstract: The volume and composition of fetal fluids in conceptuses from untreated goats and from ovariectomised goats in which pregnancy was maintained with a high (0-76 mg per kg body weight) or low (0-35 mg per kg body weight) dose of progesterone, were determined. The mean allantoic fluid volume per conceptus was similar in the untreated goats (77-0+/-13-49 ml) and the ovariectomised goats which received the higher dose of progesterone (81-4+/-18-24 ml) but was significantly greater in the ovariectomised goats which received the lower dose of progesterone (251-5+/-66-49 ml). The increase in allantoic fluid was associated with a rise in K+ concentration.
