ACS Per Diem Rates

Animal Care Services is obligated to recover the unsubsidized costs associated with the procurement, care and support of animals used in research or teaching at Texas Tech University. Investigators are billed on a monthly basis for those expenses. Bills are distributed to investigators following the month these charges were incurred. These per diem rates were determined using detailed cost accounting and a survey of the per diem rates charged by many other universities.

All charges are per animal unless specifically listed as a per cage charge. The number of animals housed per cage must conform to the standards established in the Guide for the Care and Use of Laboratory Animals or the Guide for the Care and Use of Agricultural Animals in Teaching and Research. Animals housed together must be compatible.

*New rates in affect as of 9/1/2023. For purposes of estimating annual costs for research and grant proposals, expect a minimum 3% yearly increase.

Increased Biosafety Level (BSLII) Rate Justification

The Animal Facilities are operated by the Animal Care Services (ACS) department, which operates within the Vice President for Research's (VPR) Administrative Unit. The Animal Facilities are operated as a conventional laboratory animal facility, or as an animal BSL II. Each of these increasing increments of Biosafety, however, requires additional safeguards and costs.

Laboratory animals includes rodents, and any small to medium-sized animal that the facility can safely accommodate.

Any animal research conducted in the Animal Facility must first be approved by the Institutional Animal Care and Use Committee (IACUC), the Institutional Biosafety Committee (IBC), and by the Director of Animal Care Services. Additional approvals may be required as appropriate for the type of space use anticipated.

Priority for animal research in the Animal Facilities are in the following order:

  • BSL-2 animal use
  • Conventional laboratory animals
  • Animal Quarantine

Investigators may use the procedure spaces as non-dedicated spaces at no charge, however, Investigators must decontaminate each work space after each use. If investigators require specialized equipment or a dedicated procedure/laboratory non-animal space, then a negotiated charge for that space will apply.
