Beneath the rolling hills of the UK, a silent transformation is taking place. Hidden from view, megafarms are rising, housing countless cattle in confined spaces. Over 915,000 cattle are now confined within mysterious megafarms, some holding up to 12,000 animals in unknown conditions. The numbers are growing, and so are the questions surrounding animal welfare and the future of agriculture.
Rise of UK Megafarms
In recent years, there has been a noticeable increase in large-scale cattle farms in the UK. These farms, often referred to as “megafarms,” have sparked concern among animal welfare campaigners. According to data obtained by the BBC, the number of these farms has grown from 756 to 802 in five years.
Understanding Megafarms

“Megafarm” is not a formally defined term in the UK, but it is commonly used to describe large-scale operations that confine livestock and use intensive farming practices. These farms are typically classified using the US definition of a concentrated animal feeding operation (CAFO), housing 700 dairy or 1,000 beef cattle. Currently, 802 farm operations in England, Wales, and Scotland meet these criteria.
Growth of Large-Scale Farms
The data shows that these large-scale farms now hold more than 915,000 cattle. In Northern Ireland alone, there are 141 farms with more than 700 cattle, collectively holding over 141,000 animals. Despite the growing number of large farms, the exact number of farms using continuous housing systems remains unclear.
Concerns Over Animal Welfare

Campaign group Compassion in World Farming (CiWF) has expressed deep concern over the rise in megafarms. They argue that many of these farms keep cattle indoors year-round, which can negatively impact animal welfare. Critics of intensive farming practices point to potential health risks, including the spread of disease in crowded conditions.
Farmer’s Perspective
Fraser Jones, a third-generation farmer from Wales, shared his views on indoor farming systems. He believes that indoor systems offer benefits such as protecting cattle from extreme weather and allowing better monitoring of their health. According to Jones, the key to animal welfare lies in proper livestock management and staff training.
Debate Over Grazing

A UK government survey found that only 8% of larger farms with at least 150 cattle keep their herds indoors all year. In contrast, smaller farms with fewer than 150 cattle are more likely to allow year-round grazing. This has led to debates about the impact of grazing on animal welfare and farm productivity.
Serious Concerns from Campaigners
Anthony Field, head of CiWF in the UK, expressed serious concerns about the rise of megafarms. He believes that the increase in these farms is a sign of a broken and unsustainable food system. Critics also worry about the overuse of antibiotics in intensive farming, which could lead to antimicrobial resistance.
RSPCA’s Stance

The RSPCA has also voiced its opposition to the trend of permanently housing cattle. They are concerned about the potential negative effects on animal welfare in these intensive farming systems. The organization advocates for better practices that ensure the well-being of cattle.
NFU’s Response
The National Farmers’ Union (NFU) responded to these concerns by stating that farm size is not the main factor in animal welfare. Instead, they emphasize the importance of proper livestock management and biosecurity protocols. The NFU also pointed out that continuously housed cattle megafarms are still relatively uncommon in the UK.
Average Herd Sizes

According to the Agriculture and Horticulture Development Board, the average herd size on a UK dairy farm is currently 152 cows. Most large-scale farms still practice outdoor grazing for their cattle. However, economic pressures have led to an increase in herd sizes over the past 50 years.
Economic Pressures
Professor Liam Sinclair of Harper Adams University noted that economic pressures are driving the growth of larger herds. As farms increase in size, it becomes more challenging to manage grazing. This often results in cattle being kept indoors continuously, sometimes from birth.
Government’s Position

The UK government has stated that it cannot comment on the business decisions of farms that choose to develop large-scale operations. However, all devolved governments in the UK are committed to maintaining high standards of farm animal welfare. The ongoing debate around megafarms highlights the need for balanced and sustainable farming practices.
