Abstract

Identification marking mice commonly involves ear-punching with or without anaesthetic, or tail-marking with ink. To identify which is most humane, we marked male BALB/c mice using ear-punching (EP), ear-punching with anaesthetic EMLATM cream (EP+A), or permanent marker pen (MP). We compared marked mice, their unmarked cagemates, and control mice (n=12-13/group) for 5 weeks, reapplying MP weekly. Treatment-blind observations following marking showed that EP and EP+A mice were allogroomed (P
