For how long should nonhuman primates be restrained if required by research?

The appropriate duration for which nonhuman primates should be restrained if required by research aligns with a fundamental principle of the Animal Welfare Act, which emphasizes minimizing stress and discomfort to animals. Restraint should be limited to short periods and only when absolutely necessary to ensure the well-being of the animal.

This principle is rooted in the ethical obligation to treat animals humanely, recognizing that prolonged restraint can lead to severe physical and psychological distress. The regulations encourage researchers to explore alternatives and implement the least intrusive methods possible. By advocating for restraint only for minimal timeframes, the regulations seek to promote the welfare of nonhuman primates while allowing for necessary research to be conducted.

The other options imply longer durations or a lack of consideration for the animals' well-being, which do not align with the established standards for animal care and the humane treatment expected under the Animal Welfare Act.
