A swine restraint device includes a V-shaped trough having angular blocks defining a centrally disposed, longitudinally extending channel. The angular blocks provide wedge means for supporting a swine within the trough, and at least a portion of the channel defines a bottom opening through which the feet of the swine extend when the trough is elevated relative to a stationary supporting surface. At least one yoke-shaped self-adjusting back restraint cooperates with the trough to restrain a swine in a predetermined position within the trough when the trough is elevated relative to the supporting surface. A pair of opposed shoulder stops mounted in a forward position within the trough further restrain forward motion and immobilize swine within the trough. The animal restraint device is designed efficiently to humanely and temporarily immobilize animals, particularly swine, for many purposes including weighing, veterinary exams and procedures, medication, implantation, and euthanasia. In a further aspect of the invention, the yoke-shaped back restraint cooperates with a longitudinally extending slat pivotably mounted proximate to the upper portion of the yoke to more firmly, securely and comfortably engage the animal in a restrained position within the device. In other embodiments of the invention, the free ends of the yoke-shaped back restraint are each received in telescoping relationship in tubular elements. In still another embodiment, the free ends of the yoke-shaped back restraint are resiliently mounted to a supporting surface.
