Their gills are then cut with a knife so that the fish bleed out before they are further processed. This is no longer considered a humane method of slaughter.

Gaseous (carbon dioxide) This method can be used for sheep, calves and swine. The animal is asphyxiated by the use of CO 2 gas before being killed. In several countries, CO 2 stunning is mainly used on pigs. A number of pigs enter a chamber which is then sealed and filled with 80% to 90% CO 2 in air. The pigs lose consciousness within 13 to 30 ...

Over 20 years atmospheric methane has 81 times the global warming potential of the same amount of atmospheric carbon dioxide. [ 100 ] As conditions vary a lot [ 101 ] the IPCC would like these taken into account when estimating methane emissions , in other words countries where cattle are significant should use Tier 3 methods in their national ...
The belief that it was unnecessarily cruel to slaughter an animal against its will eventually led to the compulsory adoption of stunning methods in many countries. One of the first campaigners on the matter was the eminent physician, Benjamin Ward Richardson , who spent many years of his later working life developing more 'humane' methods of ...
The methods used to slaughter mink include neck breaking, electricity, carbon monoxide, carbon dioxide, nitrogen, argon, and lethal injection. [52] The most common method of slaughter is by subjecting the animal to a chamber that contains carbon monoxide. Pelting takes place either on site or upon shipping the mink to an offsite operation.

The practice of ventilation shutdown has been called cruel by many animal welfare and animal right groups such as the Humane Society of the United States. [10] The process takes hours of high heat with one study putting the number between 1.5-3.75 hours for the egg industry. [11]
