Abstract: Behavioural responses were compared in Pietrain pigs and in Large White pigs differing by their susceptibility to the malignant hyperthermia syndrome induced by halothane. Non reactive Pietran pigs (P--) displayed a higher level of locomotor activity in a new environment than either reactive Pietrain pigs (P+) or Large White pigs. Pietran pigs performed better in a latent learning proceudre (latency of approach or feeding response, after exploration of the new environment) and in a continuound P-- did not reach significance, but P+ pigs tended to be superior to P-- animals. The three groups did not differ on a measure of passive avoidance. These results suggest that Large White pigs are characterized by a lower ability to initiate active responding when confronted with aversive events. The same would be true when Pietrain positive pigs are compared with Pietrain negative pigs, although to a lesser extent.
