Welcome to the HBLB Codes of Practice for the 2019 equine breeding season. The Codes set out voluntary recommendations to help breeders, in conjunction with their veterinary surgeons, prevent and control specific diseases in all breeds of horse and pony. Information can be found on the diseases listed here in the grey menu box to the left.

Each disease section details a number of topics, from notification procedures and clinical signs, to export certification. Use the left hand menu to navigate between each disease and relevant subsection. You can also search for information by keyword in the search facility.

Further information, including contact details for Field Service Offices, guidance and glossary of terms can be found in the  Appendix section. If you have a question, please feel free to contact the HBLB Equine Grants Department.
