What A One Feed Supplements does

A-One Feed Supplements Limited is a UK-based specialty animal nutrition company founded in 1975 and headquartered in Thirsk, North Yorkshire. The company develops and sells premium feed supplements and premixes for three primary livestock segments: piglets (its largest category), game birds, and ruminants. Following its 2024 acquisition by the Devenish Group, A-One operates as a wholly-owned subsidiary with access to the parent's Performance House research infrastructure and broader international distribution reach. Its geographic footprint covers the UK, Ireland, and — as of 2024 — Denmark as an entry point to the broader EU market.
