Abstract
Results—We found that as many sows farrowed within a 48hour period following injection into the vaginal mucosa of 25% of the recommended dose as farrowed following intramuscular (IM) injection of the full dose. Experiment 2 confirmed the efficacy of the 25% dose when injected vaginally. However, when sows were injected perianally with cloprostenol, the 50% dose proved relatively effective, but fewer farrowed within the 48-hour period when a 25% dose was used.
