ABSTRACT:
A holder for receiving and temporarily immobilizing animals such as livestock or the like while undergoing vaccination or other treatment. The holder comprises a pair of relatively lightweight frame members, pivotably interconnected at the forward end of the holder. An opening for the neck of the animal is defined between vertical bars at the forward end; this opening accommodates only the neck of the animal when the holder is closed, but enlarges for withdrawing the animal's head when the holder is open. Both entry and exit of the animal occur through the back end of the holder. The animal holder is relatively lightweight and is intended for temporary attachment to a fixed object while the holder is in use.
