Whisker trimming in mice

摘要: Whisker trimming is extremely common in strain A2G mice, with an incidence which progresses age. Over 75% of cages containing 2-3 mice have 1 or more active trimmers by the time are about 60 days old. When male were housed other strains there was a tendency for to occur most where socially dominant (as judged tube test). The number animals per cage did not seem influence this behaviour. In groups usually I untrimmed whiskers, presumably because he dominant. However, females always several trimmers. There some evidence that when became pregnant they able resist whisker their mates.
