What are key welfare and logistical challenges of housing non-human primates in research settings?

• A. Complex social needs, higher welfare standards, longer lifespans, enrichment demands, veterinary and housing costs, and ethical considerations.
• B. Small cages and limited social interaction.
• C. Shorter lifespans and minimal care.
• D. No enrichment required.

Answer: (A)

Understanding welfare and logistical challenges of housing non-human primates in research settings hinges on their complex social lives, high cognitive abilities, and long lifespans. They need stable social environments or carefully managed groupings to prevent chronic stress and injuries, which drives the need for spacious, socially compatible housing and ongoing enrichment to meet grooming, foraging, and problem-solving needs. Their longevity means facilities must support long-term care, continuous veterinary oversight, and sustained husbandry, all of which entail substantial costs for specialized housing, climate and biosafety controls, diet, and trained staff. Enrichment is essential to reduce abnormal behaviors and maintain well-being, and the ethical considerations and regulatory oversight associated with primate use require careful justification, reduction of numbers, and rigorous welfare monitoring. Other options miss these broad, real-world demands by suggesting overly simple housing, minimal care, or no enrichment, which do not reflect how primates’ needs shape both welfare and logistics.
