Quantifying a Technique Using Carbon Monoxide for the Depopulation of Swine
The project demonstrated the euthanasia of mature sows and feeder pigs using carbon monoxide (CO) produced by a 1970 gas grain truck. The gas engine system, with no modifications, had been previously used to euthanize weaned pigs. This project further improved the method by cooling and filtering particulates out of the exhaust gas prior to contact with the pigs.
Determining the efficacy and safety of differing caliber/ammunition combinations for the humane euthanization and subsequent mass depopulation of market weight pigs.
Field evaluation of humane pig euthanasia using a dump trailer as a CO2 chamber
Depopulation methods in swine: what has been done and what are the knowledge gaps
Animal caretakers perspectives on performing euthanasia on commercial sow farms
Use of modified rendering trailers to achieve rapid depopulation of modern sow units
The objective of this project was to establish an effective and safe method to facilitate both the depopulation of sow units and the disposal of carcasses in the face of a foreign animal disease outbreak.
