U-M Affiliated Instructors/Demonstrators

U-M Affiliated Instructors/Demonstrators are individuals whose primary animal activity is the leading of teaching activities or demonstration of animals or animal procedures.


Unit for Laboratory Animal Medicine. ULAM provides veterinary care to all animals housed on U-M’s campus. ULAM also manages animal ordering and acquisition, animal transport, animal husbandry and housing, personnel training, animal enrichment, and specialized research support services.

ULAM Approved Vendors

These are the larger vendors, which have a long history of robust health monitoring standards and communication of positive test results. The faculty veterinarians have established that animals from these vendors do not need to be quarantined upon arrival and can be sent directly to housing rooms. All purchase requests are handled by the ULAM Ordering Team.


ULAM Conditionally Approved Vendors

These are vendors which the faculty veterinarians have determined to meet the qualifications for providing high health status reasearch animals. However, these vendors require ongoing evaluation to ensure their health monitoring standards remain high, due to an absence of history of health status communication. The Rodent Health Surveillance Team’s (RHST’s) faculty veterinarian and/or import coordinator will review the health reports and program descriptions routinely. As long as they have this status, animals from these vendors do not need to be quarantined upon arrival and can be sent directly to housing rooms. All purchase requests are handled by the ULAM Ordering Team.


ULAM Containment Coordinator

ULAM faculty member with oversight of issues related to animals administered substances known or suspected to be hazardous to humans.

ULAM Non-Approved Vendors

This is a subset of the Approved Vendor list. These are vendors which, for any of several reasons, the faculty veterinarians have not granted either “ULAM Approved Vendor” or “ULAM Conditionally Approved Vendor” status. Animals coming from these vendors must be quarantined upon arrival, and their receipt is coordinated by the RHST’s import coordinator. For large animal shipments, the import coordinator will work closely with the faculty veterinarians. Investigators have the option of purchasing animals from these vendors themselves and going through their departments to pay for them, or having the RHST’s import coordinator work with the ULAM Business Office to do this for them.

  • Obtaining rodents from non-approved vendors: Requests for rats and mice from non-approved vendors should be directed to the ULAM Rodent Health Surveillance Team
  • Obtaining USDA species from non-approved vendors: Requests for hamsters, gerbils, guinea pigs and rabbits from non-approved vendors should be directed to the veterinary faculty for evaluation of the animal source

Ultra-PAK (Bio-PAK Prefilter)

An air filtration/dessicator system attached to each rack, except in CC where there are 1-2 installed per pod. The Prefilter is a wire-rimmed filter that is removed, washed and replaced every two weeks. The Ultra-PAK system removes particulate matter from the air and maintains a constant specific level of humidity in the room.

Unhealthy Pup

A young animal that is hunched and scruffy, quiet, lethargic or otherwise appears sick.

Unknown Cause

Veterinary Technical Staff is unable to differentiate whether the condition is spontaneous or induced by research.


United States Department of Agriculture. The USDA's Animal and Plant Health Inspection Service oversees activities involving the use of vertebrate animals at government-registered research institutions. The USDA receives its authority through federal law (Code of Federal Regulations, Title 7 and 9). Veterinary Medical Officers enforcing the 7 and 9 CFRs inspect research organizations at least annually.

USDA-Regulated Species

A term that refers to animals whose care is governed by the Animal Welfare Act. USDA-regulated Species include all live or dead warm-blooded animals used in research except birds, rats of the genus Rattus, and mice of the genus Mus bred for research. This also excludes "cold-blooded" animals such as fish, reptiles, and amphibians.

Use Number

The number assigned to each individual order (e.g., F12345) and noted on both the preprinted cage card and the delivery schedule below the PI's name and account number.
