SYSTEM AND METHOD FOR STUNNING HOGS WITH GAS

摘要

A system and method for controlled atmosphere stunning of hogs is provided. The disclosed method includes the steps of: loading hogs in a stunning chamber and sealably enclosing the stunning chamber to isolate the atmosphere therein. Carbon dioxide is then introduced and forcibly recirculated within the stunning chamber in a series of three or four phases to humanely stun the hogs. The carbon dioxide containing atmosphere is subsequently forcibly exhausted from the stunning chamber and the stunned hogs are advanced to a further processing station.
