Of 149 pregnant sows, divided into 5 groups and injected with 0.25, 0.5 or 1 mg of fenprostalene on days 112, 113 or 114 of gestation, 91-100% began to farrow within 30 hours of treatment, the majority during working hours on the day after injection. Induction of farrowing had no significant effect on the viability of the piglets, the litter weight or the subsequent sow or litter performance. Treatment of sows with fenprostalene and oxytocin on day 114 of pregnancy resulted in a reduction in the duration of farrowing compared with fenprostalene alone.
