Comparing piglet euthanasia methods, intracardial injections of T61 and pentobarbital proved most effective. These methods ensure rapid unconsciousness and death with minimal animal discomfort, addressing critical ethical concerns in animal welfare.

Area of Science:

  • Veterinary Medicine
  • Animal Welfare Science
  • Animal Ethics

Background:

  • Humane animal killing methods face public and veterinary scrutiny.
  • Evaluating euthanasia requires assessing efficacy, emotional, and ethical factors.
  • Rapidity of unconsciousness is a key indicator for humane euthanasia.

Purpose of the Study:

  • To compare four piglet euthanasia methods.
  • To assess indicators of discomfort (pain, anxiety, stress).
  • To determine the rapidity of onset of death.

Main Methods:

  • Four methods were tested on piglets requiring destruction due to swine fever prevention.
  • Methods included CO2 98%, CO2/O2 65/35%, T61, and intracardial pentobarbital (Euthesate).
  • Euthanasia efficacy was measured by absence of breathing, heartbeats, reflexes, and electro-encephalogram (EEG) isoelectricity.

Main Results:

  • Intracardial injections of T61 and pentobarbital resulted in rapid unconsciousness.
  • These methods demonstrated minimal indicators of discomfort in piglets.
  • CO2 methods were also evaluated for their efficacy and animal response.

Conclusions:

  • Intracardial T61 and pentobarbital are effective and humane methods for piglet euthanasia.
  • These methods ensure rapid loss of consciousness and death.
  • The study provides critical data for ethical considerations in animal euthanasia practices.
