  • UK Dairy Farms See Surge in ‘Battery Cow’ Intensive Farming Amid Cost Pressures
    May 26, 2026, 8:36 AM EDT. The UK has witnessed a more than doubling of intensive 'battery cow' dairy farms, which confine cows indoors year-round, rising to at least 180 units from 70 in 2015. The number of 'mega dairies' with over 700 cows also doubled to 40, driven by farmers facing soaring costs and selling milk below production cost, around 40p per litre. Despite environmental and welfare concerns linked to pollution, these large farms lack regulatory environmental permits. Major dairy processors like Arla, Müller, and Saputo profit amid struggling farmers. The trend reflects pressures on the dairy sector with calls for better oversight on factory-style production, concentrated mainly in regions like Devon, Cornwall, and Cheshire.
