I suggest you have a look at the video I posted above. I'm sure plenty slaughterhouses does a good job at mixing CO2 with something else. We only need to regulate the maximal CO2 concentration, the prices won't move neither the bacon availability but there will be much much less suffering https://edepot.wur.nl/546026 https://edepot.wur.nl/546026 > The principle of gas stunning or Controlled Atmosphere Stunning (CAS) is that animals are exposed to a high concentration of CO2, CO2 mixed with inert gases, or inert gases only > Carbon dioxide especially at high concentrations (above 40%) is pungent and painful to inhale and leads to a highly aversive response involving very loud and high-pitched vocalisations and vigorous attempts to escape from the gondola and the exposure to the gas, including scratching other pigs vigorously with the claws of the front legs and trampling of pigs that have become recumbent. Furthermore, during the induction phase animals will show increased breathing and gasping associated with signs of breathlessness (“air hunger”). Induction of unconsciousness with CO2 stunning does not immediately induce unconsciousness and the process is associated with fear, pain and respiratory distress (Verhoeven et al., 2016; Beausoleil and Mellor, 2015), lasting from the start of exposure to CO2 until loss of consciousness
