Studies on non-aversive gas stunning methods for slaughter pigs
Project
Project code: FLI-ITT-08-CE-0017
Contract period: 01.07.2011
- 30.09.2013
Purpose of research: Applied research
In recent years, several studies showed evidence of an inadequate anesthesia and of aversive reactions of slaughter pigs during gas stunning with carbon dioxide. Currently, the time to loss of consciousness as well as various ways of reducing the aversive reactions are discussed: for example by use of different concentrations of carbon dioxide or by use of alternative gases. Therefore, the lung and the brain function of slaughter pigs during exposure to carbon dioxide, argon and helium are examined in order to evaluate animal welfare aspects.
The whole-body plethysmograph to be used in the project to study lung function during gas stunning, -previously mainly used with rats, mice and dogs- proved overwhelmed due to dust exposure from the pig. The function of the pneumotachograph of the whole-body plethysmograph was no longer present even with low dust levels after the implementation of dust-reducing measures. Since the successfull further development of the dust-sensitive system components, which was not foreseeable by the manufacturer of the technology, could not be carried out as part of this third-party project, the project was ended in coordination with the funding agency.
