Save the Orchard Old Spot: How the British pork industry is erasing heritage pig breeds

The Gloucester Old Spot, once a familiar sight on English farms, is fading from the landscape. Since 2020, its breeding population has dropped by a third, a worrying sign of trouble for all eleven of Britain’s native pig breeds.

In the orchards of Berkeley Vale, along the southern edge of the River Severn in Gloucestershire, pigs once grew plump on fallen apples and leftover whey from cheese-making. With their distinctive spots, floppy ears, and gentle disposition, Gloucestershire Old Spots became known as the “Orchard Pig” or the “Cottager’s Pig”, faithful companions of the countryside for generations. Now, they’re facing a real fight to survive.

According to the Rare Breeds Survival Trust (RBST), there were just 424 registered breeding female Gloucestershire Old Spots left in 2024, a sharp drop from 636 in 2020. The breed is still listed as “At Risk” on the RBST’s Watchlist, and the number of female pigs producing registered piglets has fallen by nearly a quarter in just one year. Conservationists warn the situation is growing critical, and we may be running out of time to turn things around.

The Gloucester Old Spot isn’t the only one in trouble. Every single one of the UK’s eleven native pig breeds is now rare and at risk of disappearing. Seven breeds, including the Berkshire, British Landrace, British Lop, Large Black, Large White, Middle White, and Tamworth, are in the RBST’s most urgent “Priority” category. The other four, including the GOS, are still “At Risk.” Not a single native pig breed in the UK can be considered truly safe.

A History Shaped by Selective Breeding

To see how Britain reached this point, it helps to look back at what happened, often by design, to its pigs in the decades after World War II.

For centuries, British pigs came in all shapes and sizes. Local conditions, traditions, and preferences led to dozens of unique breeds popping up across the country, from the ginger Tamworths in the Midlands to the black-and-white Saddlebacks of Wessex and Essex, and the spotted pigs of Berkeley Vale. Each was a living record of the farmers who knew their land inside out.

After the war the rich variety began to disappear fast. Britain wanted to modernise its food system, and a government report called the Howitt Report pushed for just one type of commercial pig. Breeding programs and testing stations were set up to focus on pigs that did well in intensive, indoor farms. Those chosen breeds thrived, but most others started to fade away. Within 15 years, about a third of British pig breeds had vanished. Some, like the Cumberland or the Lincolnshire Curly Coat, are now gone forever. Even the Essex and Wessex Saddlebacks were merged into one, the British Saddleback, which is also struggling today.

This push for efficiency left commercial pig farming with a very narrow gene pool. Today, most pork comes from just a handful of carefully bred lines that grow fast, eat less, and pack on lean muscle. Traditional breeds, slower-growing, usually a bit fatter, and much better suited to life outdoors, ended up sidelined.

The Gloucester Old Spot, which was hugely popular after the First World War, just couldn’t keep up with what the modern industry wanted. By 1977, it was nearly extinct in Britain. A breed that once boasted more than 5,000 females and 1,400 boars in its herd book in a single year, setting a record for any pig breed, was reduced to just a handful of survivors.

How the Modern Market Shuts Out Heritage Breeds

The basic problem hasn’t changed. Supermarkets, which control most of the pork market in the UK, pay farmers based on strict guidelines, how much muscle a pig has in certain areas, how much fat, that sort of thing. Heritage breeds like the Old Spot, with their extra fat and different build, just don’t fit the mold, they grow at their own pace, and their meat doesn’t always fit neatly into factory packaging. In industry terms, they’re literally the wrong shape.

The result? Heritage pigs and their farmers are left on the margins. Around 90% of pork in the UK comes from intensive farms using commercial hybrids. There’s a small but growing demand for free-range and rare breed pork but it’s still niche. Farmers raising heritage pigs face constant pressure from rising costs, supermarket indifference, and cheap imports produced under lower welfare standards. Many UK pig farmers have to either ramp up production or quit altogether. When they leave, their rare breed herds disappear too. Native pigs might add about £700 million to rural economies each year, but that number hides just how fragile these small farms really are.

Take the British Lop as an example of just how fragile things have become. The RBST’s latest figures show only a dozen herds registered in 2024. The British Landrace, which was once a big player in commercial farming, almost 500 breeding females registered as recently as 2006, had dropped to just 23 by 2022.

The Gloucester Old Spot: Why Genetic Diversity Matters

The story of the Gloucester Old Spot is a real eye-opener. On paper, it’s actually the most common of the UK’s rare pig breeds. Thanks to a bit of royal attention and a special EU/UK heritage food award, it’s got the highest profile of them all, its meat is sought-after, and its easy-going nature makes it a favourite for smallholders.

And yet, numbers are still dropping. The 424 registered breeding females in 2024 only count those officially logged in the books. The real genetic pool, the thing that keeps a breed healthy for the long run, is much smaller. In some bloodlines, there are fewer than twenty breeding sows left. When the population gets this low, inbreeding risks shoot up, genetic diversity shrinks, and the animals get less resilient to disease. Breeds don’t just disappear overnight, they slowly lose their strength until bouncing back becomes almost impossible.

The British Pig Association, which keeps track of pedigree Old Spots, points out another problem: where the pigs actually live. Even if there are enough animals in total, if most of them are clustered in just a few places, a single disease outbreak could wipe out entire bloodlines.

The Old Spot’s history shows how quickly things can go wrong. Back in 1913, farmers in Berkeley Vale set up a breed society to save their local pigs from a government plan that threatened them. They managed to pull it off then. But whether the Old Spot, and its eleven native cousins, can survive today’s food system is much less certain.

The Policy Gap That Needs Closing

The RBST has made it clear they want the government to step in. The UK’s Environmental Land Management (ELM) scheme is meant to reward farmers for helping the environment and encourages using native breeds for grazing. But there’s a catch: pigs and poultry don’t graze like cows or sheep, so they’re left out of the funding. That means native pig breeds miss out on support they desperately need.

RBST chief executive Christopher Price has been outspoken about this, saying the ELM scheme “does nothing to help safeguard the future of our native pig and poultry breeds.” He’s urged the government to think about these animals in any review of the pork supply chain. The RBST also reminds us that our own choices matter, buying native breed pork from a butcher or restaurant helps keep these breeds, and the farmers who look after them, going.

For now, the Gloucester Old Spot hangs on, in rare breed farms, on the smallholdings of dedicated breeders, in the odd heritage butcher’s shop, and on royal estates in Gloucestershire. But looking at the data, it’s hard not to feel worried. Here’s a breed that took centuries to develop, survived two world wars and a brush with extinction in the 1970s, and carries a unique genetic legacy tied to the Severn Vale. Now it’s slipping away by more than a third in just four years.

The industry that once needed all this diversity just isn’t built to protect it anymore. Without real, long-term action from government, businesses, and shoppers alike, the Old Spot could disappear for good.
