Envigo is dedicated to the humane care and use of research animals. All surgical modifications are reviewed and approved in advance by Envigo’s Institutional Animal Care and Use Committee (IACUC). Envigo’s veterinarians provide oversight and technical and professional support to surgical personnel.

All surgical procedures are performed by trained and tested surgeons using aseptic technique in surgical facilities dedicated to maximum-security production barriers or isolators. Surgically-modified models are monitored postoperatively to ensure complete recovery from surgery. All animals undergoing major survival surgery (as defined by the Guide for the Care and Use of Laboratory Animals, 2011) receive post-operative analgesia to further ensure their humane and ethical care. Exceptions to analgesic requirements will require pre-approval by Envigo’s IACUC.

Envigo recognizes the need to supplement enrichment to those animals needing to be singly housed after surgery (e.g., catheterized rats). Therefore, we provide these animals with a section of inert nylabone for gnawing or provide supplemental novel material for bedding. These enrichment items are provided to animals immediately post operatively and remain with them until delivery to the client.
