Study Finds Dairy Cows Stay Consistent Methane Emitters
A new study has found that individual dairy cows remain consistently high or low methane emitters even when their diets change, suggesting that biological differences may play a greater role in methane production than previously understood. Researchers observed that feeding lactating dairy cows a higher-starch diet reduced enteric methane emissions by approximately 14%, but it…
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…
