CONTROLLED ATMOSPHERE STUNNING
If traditional dump-type
transport modules are used, either the entire module needs to
enter the stunner or birds have
to be unloaded prior to stunning, which can be a welfare
concern. Otherwise, a shift to a
drawer transport module system
is needed.
If you are considering making the change from electrical
to controlled atmosphere stunning, there are several things to
consider:
■ Cost of the system - including installation and maintenance
■ Cost of gas and power
■ Footprint necessary for the
system
■ Storage area for gas silos
with truck access
■ Dump-type transport module
systems versus drawer transport module systems
■ Inclusion of a back-up system
(like an electrical stunner) to
be used when necessary
■ Benefits to employees
■ Potential benefits of meat
quality
■ Customer demand for CAS

a much higher current than the
typical system in the U.S.
Suggestions exist that meat
quality may be improved in the
form of fewer broken wings,
fewer breast fillet hemorrhages,
and less leg damage. However,
conflicting information also
shows that wing damage is higher in CAS systems.
There is a lack of direct
comparison between electrical
stunning within U.S. parameters,
CAS, and low atmosphere stunning systems. Variations in controlled atmosphere stunning system type and gas used can also

affect end-product meat quality.
In 2012, the European
Commission Directorate General
for Heath and Consumers published a report comparing the
cost of different poultry stunning
methods which concluded CAS
had the highest cost and electrical the lowest, with low atmosphere stunning in between. It is
also important to note that the
potential cost of replacing intake
systems and transport modules
were not considered.
While CAS was estimated
to have a higher cost, there may
potentially be increased revenue.

Safe cleaning & disinfection
* Dual effect:
- Removes biofilm
- Disinfection
* Best registered product: CTGB PT02, 03, 04
* Recommended by respected poultry organizations,
hatcheries and health services.

Cost considerations
CAS will cost more than electrical stunning initially. Some
data indicates improved product
quality over electrical stunning.
However, these studies generally compare CAS to European
electrical stunning, which uses
