Rules that need to be followed for sheep identification.

Lambs born on your holding must be identified before they move off the holding of birth or before they reach:

  • 6 months of age for sheep kept under intensive husbandry systems (i.e. housed rather than on grass)
  • 9 months of age for sheep kept under extensive husbandry systems.


If you require further assistance on the tagging rules, please telephone the Livestock ID helpline 03000 255022 or contact a member of the Farm Liaison Service.
