Summary. A single i.m. injection of 5 mg PGF-2α evoked a significant elevation of plasma oxytocin values in sows 6 days post partum and during dioestrus. Plasma vasopressin levels in dioestrous sows were not significantly affected by PGF-2α. It is concluded that circulating steroid levels do not interfere with the response of oxytocin levels to PGF-2α.
