Danish pig farmers know all about this. They’ve discovered that artificial insemination is more effective if preceded by manual stimulation of the clitoris, cervix and flanks. So they’ve taken a practical approach and developed a special five-step sow stimulation routine, with graphic images for guidance. Seduction starts with the farmer stimulating the sow with a fist, moves on to massaging her hips and finishes with the farmer sitting on her back to mimic the weight of the mating male on her.
