Definition of key terms used in breeding and colony management.
A high level introduction to best practice in mouse colony management, including confirming, archiving and maintaining mouse strains.
Archiving can provide a back-up to production colonies, minimise genetic drift, reduce the need for tick-over colonies and preserve valuable models.
Intermittent breeding should be used instead of constant mating to avoid unnecessary wastage of animals, whilst retaining the ability to breed an
Specifically around re-starting breeding and animal experiments after a pause (e.g. work with mice after the COVID-19 lockdown).
