Peripheral Plasma Progesterone and Corticoid Levels at Parturition in the Sow1

D. B. Killian, H. A. Garverick and B. N. Day2

Missouri Agricultural Experiment Station,3, Columbia 65201

Abstract

Plasma levels of progesterone and corticoids were determined in eight sows prior to, during and following parturition. A statistically significantdiurnal variation was observed with morningsamples having a higher level of corticoids. Progesterone levels decreased through the last day of gestation to a low level at day 1 postpartum. Mean corticoid levels increased during the last 24-hr. prepartum and returned to prepartum levels within 36 hr. of farrowing. The elevation in corticoid levels is interpreted to be a result rather than a cause of parturition.
