Humane Euthanasia Standards

As industry professionals working with federally funded projects, we are required to follow strict guidelines set by Institutional Animal Care and Use Committees (IACUC). These standards ensure that all animal handling and euthanasia practices are conducted responsibly and ethically.

The American Veterinary Medical Association (AVMA) provides science-based guidelines for humane euthanasia, focusing on methods that deliver the quickest, most painless, and least stressful outcome possible.

Approved Method

According to AVMA guidelines, a bullet to the brain is considered a humane method of euthanasia for feral swine once captured.

Our research protocols require that pigs be euthanized inside the trap enclosure using:

• A single, well-placed shot
• A .22 caliber suppressed rifle
• 45-grain subsonic ammunition
• Within one hour of capture

This approach ensures a rapid and humane process while minimizing stress.

Why Timing Matters

Euthanizing feral pigs within one hour of capture serves several important purposes:

• Reduces the amount of time animals spend confined
• Minimizes stress and distress
• Supports compliance with humane treatment standards

Because most captures occur at night, this timeline is critical for maintaining animal welfare.

Reducing Disturbance and Learned Behavior

This method also helps prevent behaviors that could impact future M.I.N.E.^® Trapping process success:

• Limits distressed vocalizations that could alert other sounders
• Reduces the risk of pigs learning and avoiding traps in the future

By controlling these factors, the effectiveness of the trapping system is preserved over time.

Maintaining Trap Effectiveness

Euthanizing animals promptly also keeps the trap environment clean and functional:

• Prevents excessive waste buildup inside the enclosure
• Reduces the likelihood of contamination that could affect future captures

It’s important to note that the presence of blood inside the trap does not deter new sounders from entering and feeding.

Why Night Operations Are Used

Most euthanizing operations take place at night for both practical and humane reasons:

• Feral pigs are naturally nocturnal
• A 1200-lumen light can temporarily immobilize them, reducing movement
• Less movement means less risk of injury to both animals and equipment

Nighttime conditions also reduce the likelihood of aggressive escape attempts compared to daytime captures.
