A Juas goat is a trained goat used at a slaughterhouse and in general animal herding. The Judas goat is trained to associate with sheep or cattle, leading them to a specific destination. In stockyards, a Judas goat will lead sheep to slaughter, while its own life is spared. Judas goats are also used to lead other animals to specific pens and on to trucks. The term is a reference to the biblical traitor Judas Iscariot.
