immediate sacrifice; emergency slaughter

Immediate sacrifice of laboratory animals is carried out at an appropriate time from the viewpoint of animal welfare.
Emergency slaughter of the severely injured livestock was performed.
安楽死 is a broader term for euthanasia, often used for pets or humans, while 切迫屠殺 specifically refers to urgent killing of animals in research or farming to prevent suffering.
屠殺 means slaughter in general, without the nuance of urgency or humane necessity that 切迫屠殺 carries.
Compound of 切迫 (urgency, imminence) and 屠殺 (slaughter). The term is a modern technical coinage, likely from veterinary or laboratory animal science.
