Enrichment strategies can significantly improve the welfare of captive primates. Appropriate environmental enrichment reduces abnormal behaviors and aggression, enhancing their value as research and educational models.

Area of Science:

  • Primate Welfare
  • Animal Behavior
  • Applied Ethology

Background:

  • Captive primates in laboratories and zoos can develop behavioral abnormalities, including self-harm, due to impoverished conditions.
  • These abnormalities diminish the animals' psychological well-being and compromise their utility as research and educational models.

Purpose of the Study:

  • To review literature on improving living conditions for captive primates.
  • To assess the effectiveness of various enrichment strategies in correcting behavioral abnormalities and reducing aggression.

Main Methods:

  • Systematic review of published research on primate housing, feeding, physical, sensory, and social enrichment.
  • Analysis of the impact of enrichment on aggressive behavior and behavioral variation.

Main Results:

  • Inappropriate or poorly distributed enrichment can increase aggressive competition among primates.
  • Species, sex, age, and background-appropriate enrichment significantly reduces aggression and abnormal behaviors.

Conclusions:

  • Tailored enrichment is crucial for improving captive primate welfare.
  • Effective enrichment can eliminate abnormal behaviors and enhance the overall well-being of primates in captivity.
