Budgets will be devolved from 1 April 2011and have been shared based on historic spending and animal numbers.
Animal Health and Welfare funding is spent primarily on preventing, controlling and eradicating exotic and endemic diseases, notably bovine TB, and ensuring high standards of animal welfare.
Research and surveillance will continue to be centrally funded to maintain scientific capacity and capability in Great Britain. Each administration will identify their needs and jointly decide what research and surveillance to commission, and will work closely with Northern Ireland.
In the event of a disease outbreak, all countries will continue to work very closely together to ensure the most effective measures are taken across Britain.
