The details differ by species and by nation, and they change — always check the current official guidance before you buy, sell or move animals. The general principles are:
- Register your holding and follow the identification and tagging rules for your species.
- Keep up-to-date records of animals on and off the holding, and of medicines used.
- Movements are usually reportable within set time limits and some need a licence or standstill.
- Keep the paperwork — inspections are far easier when it is in order.
