Enhancing Gerbil Welfare Through Positive Reinforcement Training in Research Environments

Area of Science:

• Laboratory animal science
• Animal behavior
• Biomedical research

Background:

• Minimizing stress and promoting species-appropriate handling are crucial for laboratory animal welfare.
• Clicker training, a positive reinforcement technique, has been shown to reduce stress and improve learning in mice and rats.

Purpose of the Study:

• To adapt and evaluate clicker training for Mongolian gerbils (Meriones unguiculatus).
• To assess the impact of clicker training on gerbil behavior, anxiety, and human interaction.

Main Methods:

• A cohort of 43 gerbils underwent a 10-day standardized clicker training protocol.
• Behavioral assessments included the Open Field Test and a human interaction test post-training.

Main Results:

• Clicker training was fast, efficient, and well-tolerated in gerbils.
• Trained gerbils, especially females, exhibited increased voluntary interaction and reduced anxiety-like behaviors.
• The training protocol successfully encouraged voluntary approach and interaction with experimenters.

Conclusions:

• Species-adapted clicker training is a viable method for improving gerbil welfare.
• This training fosters trust between experimenters and animals, reducing stress.
• Improved animal welfare can lead to more reliable experimental outcomes.
