 Our Mission

The Laboratory Animal Resources Center is committed to providing UTSA faculty, staff and students with high quality, cost-effective research animal resources. LARC provides veterinary and personnel training and expertise in laboratory animal technology and medicine.

LARC is dedicated to support the University’s research and teaching goals, to promote and assure humane care and use of animals through compliance with the Animal Welfare Act, Office of Laboratory Animal Welfare, Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) International and University policies for the humane care and use of animals.

The LARC advises and educates researchers, staff and students on animal experimentation issues and promotes best practices for the responsible use of animals. These actions result in Quality Science Merging with Animal Welfare.

Our Philosophy

Our primary concern is the welfare of the animals used in the facility. We maintain vigilance in ensuring that the animals experience proper care and handling with minimal discomfort or pain, as well as live in an enriching environment. We adopt and abide by the American College of Laboratory Animal Medicine’s Position Statement regarding animal experimentation.
