Counting Mice and Rats in Breeding Colonies

REVISED: November 2020

All mice and rats born in-house must be counted and will be deducted from IACUC protocols.  Depending on the expectations between the PI and DLAR, either the investigator, the laboratory staff or DLAR staff must record the number of pups born on the DLAR "Bred/Wean" form so that an accurate count can be provided to the DLAR Business Office. 

The IACUC requires the inclusion of any mice or rats that are culled prior to weaning in IACUC protocols.
