Induction of parturition in crossbred sows with cloprostenol, an analogue of prostaglandin F2α
Forty-six crossbred sows were treated with a single intramuscular injection of 175 μg of cloprostenol on day 110, 112 or 113 of gestation and compared with 46 control animals farrowing naturally during the same period. Of the treated animals, 96% farrowed within 48 h. The mean time to the induced fa...
