Preparturient changes in allantoic fluid and fetal plasma from chronically catheterised ewes
Research in Veterinary Science
|May 1, 1975
Before birth a marked rise in the potassium/sodium concentration ratio of allantoic fluid coincided with a similar rise in the corticosteroid levels of fetal plasma. The prepartum corticosteroid increase started at 134-136 days gestational age whether delivery occurred at 141 or 151 days.
