Background:

Ethical, scientific, and legal imperatives mandate minimizing animal suffering in research.
Accurate assessment of animal pain and distress is essential for humane experimental practices.

Purpose of the Study:

To present a novel approach for recognizing and assessing animal pain and distress.
To introduce a score sheet system to aid in evaluating animal welfare during experimentation.
To facilitate the determination and validation of humane endpoints in animal studies.

Main Methods:

Utilizing clinical signs for the recognition and assessment of animal pain and distress.
Implementing a score sheet system to systematically record observations.
Applying the system to safety testing of biological products in animals.

Main Results:

The score sheet system aids in identifying new scientific responses to experimental procedures.
The system provides a validated method for determining humane endpoints.
Examples demonstrate the practical application of the score sheet in animal safety testing.

Conclusions:

The described score sheet system effectively supports the ethical conduct of animal experimentation.
This approach enhances the ability to monitor and manage animal welfare, ensuring minimal suffering.
The system is valuable for validating humane endpoints in regulatory safety testing.
