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.
