Last Review Date: January 3, 2018

I. Purpose

This Standard Operating Procedure (SOP) outlines the animal care requirements associated with the daily husbandry of guinea pigs to ensure consistent and uniform care. This procedure applies to all personnel involved in the care of guinea pigs housed in static micro-isolator caging in the Laboratory Animal Resources (LAR) facility on the campus of the University of Montana.

II. Policy

It is an LAR policy to meet or exceed all federal, state, and local regulations and guidelines and to comply with all institutional policies and procedures as they apply to the use of animals in research. LAR personnel must pass on-line animal training modules and attend applicable training in animal care and use, occupational health and safety, and equipment operation prior to performing activities outlined in this SOP. Animal housing rooms should be entered using appropriate personal protective gear for the species and disease or hazard containment level.
