About Berkshire
Berkshire pigs are a rare breed of pig originating from Berkshire in England. Herds of the breed are still maintained in England by the Rare Breeds Survival Trust at Aldenham Country Park, Hertfordshire, and by the South of England Rare Breeds Centre in Kent. The Berkshire is listed as 'vulnerable', as in 2008 fewer than 300 breeding sows were known to exist. Some pigs of the breed are also kept in New Zealand, but it is estimated that there are now fewer than a hundred purebred sows there.
