This study was based on a simple test which consists in moving the hand near to the snout of a sow and observing its reaction. Sows that did not try to avoid contact were considered as confident. An average level of fear of humans was determined for each herd. The higher the level of fear is, the lower is the number of weaned piglets per sow per year and the longer is the fecondant mating weaning interval. The automation of feeding has obviously led stockpersons to be less present within the herd and has led sows to associate humans only to rather negative events (vaccination, handling). This study shows that the human-animal relationship is not to be overlooked and significantly influences reproductive performance.
