HorseHage is celebrating its 40th anniversary this year. The company produces dust-free forage for horses and was established when the late Mark Westaway (Senior) became concerned about his event horse persistently coughing. After being told by a vet that the coughing was dust-related, he set out to produce dust-free forage to prevent the problem.

The HorseHage brand has been developed by the company Mark Westaway and Son, and is now headed by Mark Senior's son (also called Mark) and his brother-in-law, Chris Tar.

The company was awarded the Royal Warrant in 1983 after Her Majesty the Queen's horse, Burmese, was fed HorseHage when suffering from a respiratory problem. HorseHage is also the Official Forage supplier to Equestrian GB and has been supplied to the British Equestrian Teams at every Olympic Games, from Los Angeles in 1984 to the present day.
