  • Patent number: 5163383
    Abstract: The present invention provides apparatus for inverting sheep into a reclined position for examination and treatment. The apparatus provides a holding bed that can be positioned to a first position to receive a sheep that is being inverted by the technique used by sheep-shearers, and can then be positioned to a second position which places the sheep in a reclined position on its rump and back with its feet pointing upward. The method of inverting the sheep into the bed, when the bed is located at its first position, is non-threatening to the sheep and the sheep ends up laying in the bed without struggling. When the bed is then shifted to its second, examining and treating, position, the sheep feels secure, unthreatened, and therefore reclines comparatively comfortably without struggling.
