A Judas Goat is a term used to describe 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 onto trucks. The term Judas Goat is derived
from a biblical reference to Judas Iscariot [who is known for betraying Jesus Christ to the Pharisees].
“The phrase has also been used to describe a goat that is used to find feral goats that are targeted for eradication. The Judas Goat is outfitted with a transmitter, painted red and then released. The goat then finds the remaining herds of wild goats, allowing hunters to exterminate them.
—From Wikipedia, the Internet encyclopedia.
“. . .Lambs were being led by a Judas goat into the chute. Two workers stood at the end, jolting the animals with enough electricity to render them brain dead. In an instant, prongs at the sheep’s brains and in the fleece near their hearts delivered a zap that collapsed them, after which they were handed through . . . to the kill floor.The Judas goats . . . then returned to the pens, where they collected another batch of sheep.”
