Summary

Modifications to nonhuman primate (NHP) caging, including perches and tunnels, were developed to support group housing. These enhancements meet regulatory standards and promote animal welfare for macaques in research settings.

Area of Science:

  • Veterinary Science
  • Animal Behavior
  • Laboratory Animal Science

Background:

  • Regulatory requirements, such as the Animal Welfare Act, increasingly mandate group housing for nonhuman primates (NHP).
  • Growing scientific evidence supports the benefits of group housing for the welfare of most NHP species.
  • Existing caging infrastructure may not readily accommodate group housing arrangements.

Purpose of the Study:

  • To describe modifications to existing nonhuman primate caging to facilitate group housing.
  • To introduce easily sanitizable, semi-permanent enrichment devices compatible with standard cage functions.
  • To provide practical solutions for implementing group housing in research settings.

Main Methods:

  • Fabrication of perches and cage-connecting tunnels for existing macaque caging.

  • Ensuring modifications are semi-permanent and allow for easy sanitization.
  • Verifying that all standard cage functions remain operational with the added modifications.

    • Main Results:

    • Developed and implemented perches and tunnels for macaque caging.
    • Modifications were found to be semi-permanent, easily sanitizable, and did not impede cage functions.
    • Enabled the housing of nonhuman primates in a group setting within modified cages.

    Conclusions:

    • The described caging modifications effectively support group housing for macaques.
    • These enhancements address regulatory and welfare considerations for laboratory nonhuman primates.
    • The fabricated perches and tunnels offer a practical approach to improving NHP welfare through environmental enrichment and social housing.
