Controlled atmosphere stunning systems have
become popular for large turkey in the U.S. but
have not been widely adopted for broilers in
North America. Image courtesy of Marel Poultry.

Costs, benefits of controlled
atmosphere stunning
Controlled atmosphere stunning is more expensive than electrical
stunning, but it carries animal welfare and potential marketing
benefits.
DIANNA BOURASSA

The majority of broilers in the U.S. are
stunned by the use of electrical current, however,
this may be changing.
Driven by a perceived animal welfare improvement, there is a movement toward controlled atmosphere stunning (CAS). There are
certainly some animal welfare benefits to CAS,

but there are drawbacks as well.
With controlled atmosphere stunning systems,
broilers are irreversibly stunned prior to shackling. This eliminates animal welfare concerns
during this step in the process. Irreversible stunning prior to shackling also benefits the hanging
crew by providing a cleaner work environment
