8.8 Culling of pigs
Pigs infected with ASF must be culled/slaughtered immediately using humane methods which should result in immediate death or immediate loss of consciousness lasting until death. For biosecurity considerations, infected animals should be killed first, followed by in-contact animals, and then the remaining animals. Different methods of humane killing have been adopted based on different age groups of animals. The neonatal pigs can be killed with free bullet, non-penetrative captive bolt, electrical applications, CO2/ air mixture, nitrogen or inert gas mixed with CO2 and injection with barbiturates. Whereas, the adult pigs can be killed using free bullets, electrical applications and injection with barbiturates (OIE, 2019b). The operational procedures of killing should be adopted keeping in view the biosecurity and environmental aspects.
