Clinical and endocrinological aspects of induced parturition in multiparous sows

Abstract:
Intramuscular administration of PGF2alpha or its analogue ICI 80996 at 110--112 days of gestation results in grouped parturition. The decrease of progesterone levels is interrupted by a temporary increase. During expulsion rather high values are obtained compared to the control group. Unconjugated oestrogens increase, reaching maximum values just before expulsion.
