In the scope of the proposed project an alternative to the electrical bath stunning of broilers shall be implemented and the application of the alternative stunning method standardized. The innovative alternative in the proposed project is the "Controlled Atmosphere Stunning" (CAS) System, by which broilers are stunned by the use of carbon dioxide in multiple phases. During the course of the project the stunning system in a broiler slaughterhouse shall be converted from an electrical bath stun to an alternative CAS stunning system. By the use of a CAS stunning system, the broilers are hung into the evisceration line in a state in which they are not perceptive. Through this, the working conditions of the personnel working at the slaughterhouse can be eased, because they do not have to handle animals which are not stunned and might show aversive reactions (e.g. flapping of wings). The unconscious and motionless broilers can be hung into the shackling line considering and improving animal welfare and working conditions of the personnel and the broilers do not suffer stress when they are dumped from the containers, because they are stunned in the containers and afterwards hung into the shackles. In the scope of the project, before and after the installation of the CAS system animal welfare relevant aspects, aspects of the working conditions and the quality of carcasses will be assessed. Hereby, the implementation of this innovative alternative shall be supervised scientifically. The target goals of the project are the improvement of animal welfare, the working conditions and the quality of the carcasses of the slaughtered broilers. For this purpose, all animal welfare relevant aspects (before and after implementation of the CAS system) as well as damages of the carcasses which are due to the stunning system (e.g. hemorrhage, fractures of the furcular, red coloring of the meat) will be assessed and the staff of the slaughter house interviewed.
