Prolonged Heatwave Reduces UK Milk Production by 20%

The dairy sector in southern England is facing severe challenges due to an extended heatwave and drought conditions. High temperatures and lack of rainfall have stressed livestock, leading to a decline in milk production. Some farms have reported a reduction in milk yields by as much as 20%, according to Professor Nicola Cannon of the Royal Agricultural University.

The drought has severely depleted soil moisture, hampering grass regrowth after harvesting for hay and silage, thereby limiting natural grazing for cattle. As a result, many farmers have resorted to using their winter forage reserves to maintain livestock nutrition during the summer. This early use of stored feed presents a financial risk, as farmers will need to purchase costly supplemental feed later in the year.

To mitigate the effects of extreme heat, dairy operations are investing in infrastructure improvements such as industrial fans, enhanced ventilation, and livestock cooling systems. While these measures help stabilize milk output and safeguard animal welfare, they add to the financial burden faced by producers already dealing with high energy prices, volatile feed costs, and labor shortages.

With forecasts predicting continued dry weather in southern Britain, experts warn that climate-induced weather extremes are becoming a significant threat to the UK agriculture sector. This situation highlights the urgent need for investment in supply chain resilience and climate adaptation strategies to ensure long-term food security.
