History and Evolution
Until the eighteenth century, the Berkshire was characterized as a large, tawny-colored pig with lop ears and occasional dark patches. However, during the late eighteenth and early nineteenth centuries, the breed underwent significant modification through cross-breeding with small black pigs imported from Asia, resulting in the appearance known today.
In its native United Kingdom, the breed has faced population challenges. The Rare Breeds Survival Trust (RBST) listed the Berkshire as vulnerable in 2008, noting fewer than 300 breeding sows at that time. Despite this, the breed has seen a resurgence in popularity, partly driven by its association with high-end pork marketing in Japan.
Today, conservation efforts continue in England through the South of England Rare Breeds Centre in Kent and the RBST at Aldenham Country Park in Hertfordshire.
Global Distribution and Impact
The Berkshire has been exported worldwide, with 23 countries reporting the breed to the Food and Agriculture Organization (FAO) DAD-IS database across the Americas, Asia, Europe, and Oceania.
The United States
Exports to the U.S. began in the early nineteenth century. In 1875, the American Berkshire Association was established as the first-ever breed society for pigs. Notably, the first registered pig was a boar named Ace of Spades, who was reportedly bred by Queen Victoria.
Japan and the Kurobuta Legacy
Introduced to Japan in the 1860s, the breed flourished, with populations exceeding 330,000 by 2007. A specific derivative, the Kagoshima Berkshire—descended from two British Berkshires imported in the 1930s—is now considered a separate breed. Its meat is marketed as Kurobuta pork, often commanding a premium price due to its perceived quality, sometimes described as the "wagyu of pork."
Physical Characteristics
The Berkshire is a medium-sized pig characterized by its prick ears (upright ears) and a predominantly black coat. It is easily identified by six specific white markings: four white "socks" on the lower legs, a white splash on the snout, and a white tip on the tail.

Meat Quality and Use
The primary purpose of the Berkshire is pork production. Interestingly, the meat typically has a relatively low pH. While high pH is generally correlated with consumer satisfaction in commodity pork, the Berkshire has performed exceptionally well in taste tests, particularly in the United States, where it is highly rated for its flavor profile.
