Per Diem Rates

Per Diem Rates (BUMC & CRC)

To recover a portion of the money spent on animal care, per diem rates for the various species are charged by the Animal Science Center (ASC). Depending upon a researcher’s affiliation within or to the University and the sources of funding, different per diem rates may apply than are posted below. Per diem rates are established by the University and published on an annual basis.  Please contact the ASC main office at (617) 638-4086 if you have any questions about your applicable rates or affiliation status.


Per diems will be charged for each day or fraction of a day that a cage or animal is within an ASC managed space.  Per diems will not be pro-rated.  Cage/animal census counting will be based upon ASC policies and standard practices.

Effective March 1,2014, Boston University is implementing new animal rates for all BU faculty located on the Charles River and Medical Campuses. The uniform pricing has been developed in recognition of the increasing numbers of faculty who are collaborating across the University campuses. The table below shows the university subsidized cost charged to PIs, as well as the full cost of the per diems for the individual species.   Please note these rates are exclusive of BSL-3 and BSL-4 research.

Species PI Cost Full Cost
Cat $11.95 $78.20
Chicken $5.00 $40.59
Chinchilla $5.12 $16.68
Ferret $3.64 $31.87
Frog $0.45 $11.24
Gerbil $0.68 $77.50
Monkey $17.05 $46.35
Mouse – Healthy $1.01 $2.57
Mouse – Isolation $1.26 $2.57
Pig $44.96 $175.00
Rabbit $5.33 $74.03
Rat $0.75 $2.96
Zebrafish $0.18 $1.88

Boston University will continue to subsidize the costs of animal housing as part of its investment in the research enterprise. The subsidized rates are intended only for faculty supported by federal, foundation or private grants for which the F&A is at the BU negotiated rate or the maximum rate allowed by the sponsor.

Authorization for Animal Housing and Special Services Costs

  1. Download the Animal Authorization for Animal Housing and Special Services Form
  2. Contact ASC for rates regarding any species not listed above.
  3. Per diem (daily) rate covers standard feed, standard bedding, cage changing and sanitization at the standard interval for the species, routine health monitoring, and veterinary care for naturally-occurring diseases as described in the per diem overview. Other services may be provided on a fee for service basis. One-time set-up, conditioning, or quarantine charges may also apply for animal purchases.
  4. Click on Rodent Cage Capacity Policy to find the maximum number of mice and rats that can be housed in each cage.

Instructions for Authorization for Animal Housing and Special Services Costs For

Investigators, with the exception of BMC Investigators, must submit a BUworks Internal Service Request (ISR) when placing animal orders. BMC Investigators must continue to use ASC animal order form when placing animal orders. All Investigators who house animals at the ASC should immediately submit a signed Authorization for Animal Housing and Special Services Costs Form to the ASC. The form will be used to confirm eligibility for a grant to qualify for the per diem rate. Grants not eligible will be billed at the full per diem rate.  We must receive a completed form prior to or at the same time of your first animal purchase.

Authorization forms may be forwarded to the Med Campus Business Office, 700 Albany Street, W707, 617-638-4055 (f) or Charles River Campus Business Office, 5 Cummington Street, 617-353-4527 (f). When completing this form, please remember that the Principal Investigator and the protocol number MUST match. The User of the animals can be different and the owner of the grant funds used to pay housing costs can be different but the Principal Investigator and the protocol number MUST match.

You may use one form or multiple Authorization Forms to indicate the funding (BMC activity number or BU source number) for your animals. One form is sufficient if all your animals are to be supported by the same source or set of sources. If you want to use different sources for different groups of animals, two or more forms must be submitted. If different sources are used to support subsets of animals within the same animal species, the animals’ cage cards must be marked by the Investigator to indicate which source is to be charged for each cage. ASC will then establish separate census sheets for each funding source to be used. If you wish to explore this option, please either contact a member of the Animal Care management staff for further details or use our general contact form.

This new authorization form offers Investigators more flexibility so that grant funds are not encumbered, source changes are easier to process, and payments can be made by more expeditiously. Please contact the Med Campus Business Office (617) 638-5280 or the Charles River Campus Business Office 617-353-5415 if you have any questions concerning this process.
