Heat Stress Found to Cut Milk Quality and Yield
New research from Cornell University has revealed that heat stress affects dairy farmers more severely than previously understood by reducing not only milk production but also the fat and protein content of milk. Analyzing data from approximately 6.5 million cows and around 120 million milk production records across the United States between 2007 and 2016,…
Heat Stress Threatens Dairy Milk Quality and Farmer Returns
New research from Cornell University has revealed that heat stress affects not only the quantity of milk produced by dairy cows but also its nutritional quality, potentially doubling the economic impact on dairy farmers. An analysis of data from approximately 6.5 million dairy cows across 43 U.S. states between 2007 and 2016 found that rising…
Climate Change Threatens Milk Quality and Output
Climate change is emerging as a growing threat not only to the quantity of milk produced worldwide but also to overall dairy productivity, despite significant investments in cooling technologies and farm adaptation measures. New research analyzing data from more than 130,000 dairy cows across Israel over a 12-year period found that a single day of…
Greenpeace Challenges NZ Dairy Efficiency Claims
Environmental group Greenpeace Aotearoa has questioned the long-standing claim that New Zealand dairy farming is the “most efficient in the world,” arguing that the assertion is not fully supported by available scientific evidence. In a recent commentary published during New Zealand’s annual agricultural event, Fieldays, Greenpeace campaigner Amanda Larsson said policymakers and industry representatives continue…
Punjab Heatwave Raises Cattle Health Concerns
Rising temperatures across Punjab are increasing health risks for dairy cattle, with veterinary experts warning farmers about a sharp rise in constipation and digestive disorders during the peak summer season. Specialists from Punjab Agricultural University’s Krishi Vigyan Kendra (KVK) said cases of impaction and constipation become significantly more common during extreme heat conditions, particularly when…
Heatwaves Threaten India’s Dairy Supply Chain
India’s dairy supply chain is facing mounting pressure as temperatures across several regions cross 45°C, raising serious concerns around milk safety, spoilage and cold-chain efficiency. Experts warn that extreme heatwaves are no longer just a climate issue — they are rapidly becoming a major food safety and public health challenge for the dairy industry. (https://www.boldsky.com/)…
Methane leaks threaten dairy digester gains
A new study highlights that while methane digesters on dairy farms are largely effective, rare but massive leaks can erase much of their climate benefit, raising concerns about long-term sustainability. The research, led by scientists at the University of California, Riverside, analyzed 98 dairies across California over eight years using satellite and airborne data, tracking…
