The Agriculture and Horticulture Development Board (AHDB) is a levy board funded by farmers and growers and some other parts of the supply chain. It aims to enhance farm business efficiency and competitiveness in the areas of: pig, beef and lamb production in England; milk, potatoes and horticulture in Great Britain; and cereals and oilseeds in the UK. It undertakes research and development and farm-level knowledge transfer activity, provides essential market information to improve supply chain transparency and undertakes marketing promotion activities to help stimulate demand and to develop export markets. These are activities which most individual farm businesses could not afford to do themselves.
