Euthanasia is a practice in pig production that has welfare and economic impact. It is essential to understand when euthanasia should be carried out and that it is done properly to limit suffering of the pig. Early weaning of compromised piglets has both welfare and economic benefits. When a pigs birth weight is less than 0.9kgs it will rarely turn into profit for the producer so euthanasia will limit feed and maintenance costs and improves overall herd welfare. For pigs under twelve pounds there are three acceptable euthanasia methods, blunt force trauma, overdose on anesthesia and CO2 poisoning. Blunt force trauma is the most common method and fairly simple to carry out, but aesthetically it is not the most ideal method. An alternative to BFT is a non-penetrating captive bolt which has been deamed acceptable for suckling pigs. Co2 poisoning involves exposing a pig to greater than 90% CO2 for five minutes. Although this method is effective at causing death, it can appear inhumane as pigs squeal while being gassed, try to escape, and have high cortisone levels which suggests the pig has suffered increased stress. When choosing a euthanasia procedure producers should have clear guidelines about which piglets should be euthanized as well as how the procedure is carried out. To assess sensibility the pigs should be tested immediatly after the euthanasia. If the pig still has a brain or spinal reflex it is still considered sensible and the euthanasia attempt must be repeated. If physical contact is not possible behavior tests can be done by obseving absence of breathing, lack of muscle tone and abasence of vocalization.
