Rodent Breeder Colony Management

The Rodent Breeder Colony Management (RBCM) CoRE at the Icahn School of Medicine at Mount Sinai offers a way for investigators to create and manage rodent colonies in an efficient manner.

The RBCM staff will provide the services freeing your staff to concentrate on lab work.

  • You will no longer have to designate someone in your lab to be responsible for maintaining the Colony.
  • You can eliminate concerns about fees for overcrowded cages and unwanted breeding between parents and the offspring.
  • The RBCM program will set up mating pairs, weaning, tail snips, ID animals and record keeping.
  • You will be notified on the status of your rodent colony: births, weaning and deaths through weekly email reports. (Please note colonies established outside of colony management services will take longer to rotate to a colony management record keeping format).

The cost for the service is $1.20, which includes the following services: setting breeders, checking for plugs, weaning, and tail or ear biopsy for genetic analysis. We will efficiently organized colony resulting in smoothly run experiments.

(Note that our lab does not make euthanization decisions, and that we must receive written notice before we terminate breeding services.)

FAQs, Rodent Breeder Colony Management

Following are our answers to the most frequently asked questions of the Rodent Breeder Colony Management CoRE.

A:  No, multiple males will encourage territorial fighting amongst the males, consequently breeding will not occur.

A: No, the mice are not sexually mature. The offspring should be between 6-8 weeks of age then set as breeders.

A: Contact any of the individuals listed under “Meet The Team.” You will be contacted to setup a meeting to discuss your project needs. Once approved to enter the colony management program a project request form must be completed. The lab will then identify the animals to go into the program and submit a CCMS transfer form and / or order the animals from an approved vendor. If the animals are imported from another institution they must be rederived before enter the colony management program. Please note animals originating from conventional housing cannot enter the program unless rederived. Animals from CCMS barrier housing will be tested via Optispot to confirm health status prior to transfer
