Environmentally induced stereotypies in gestating sows were inhibited by haloperidol. This inhibitory effect was stronger in sows that directed stereotyped activities toward objects in the environment than in sows performing self-directed stereotypies. The results indicate that dopamine is involved in the performance of stereotypies in pigs, and that haloperidol seem to impair motivational arousal primarily by reducing the rewarding impact of stereotyped self-stimulation.
氟哌啶醇可抑制妊娠母猪由环境诱发的刻板行为。对于那些将刻板行为指向环境中物体的母猪，这种抑制作用比那些表现出自发性刻板行为的母猪更强。结果表明，多巴胺参与了猪的刻板行为，而且氟哌啶醇似乎主要通过降低刻板自我刺激的奖赏作用来损害动机唤醒。
