Several advantages can be found when implementing timely and well-planned euthanasia’s. Unnecessary suffering and costs are both reduced and welfare is improved due to a higher chance of survival of the other piglets. The most common euthanasia method in Canada is blunt force trauma, but Zephyr is a possible alternative. When using Zephyr, the piglet should be placed in the animal restraint sling, before firing the Zephyr air gun twice on the piglets head. This method can be used in piglets up to 9 kg (20 lbs) and is much more aesthetically acceptable than blunt force trauma.
