The authors describe the synchronization of farrowing by the induction of parturition with a prostaglandin F2alpha analogue (Cloprostenol). The time sequence of the beginning of parturitions was recorded in 147 sows after administration of 175 microgram Cloprostenol. 93.7% of the parturitions take place between the 14th and 39th hour after administration, the peak time being between the 24th and 27th hour (31.2%). The schedule of the farrowing days is described as a prerequisite for a qualitative change in the organization of work in large pig herds.
