Researchers at the University of California, Davis have discovered that adding grape pomace from winemaking waste to dairy cow feed reduces methane emissions by 10% to 11%. This sustainable approach not only helps in cutting greenhouse gases but also enhances milk quality by increasing polyunsaturated fats.
The study, which further aligns with California's climate goals, reveals that grape pomace improves feed efficiency without compromising the milk's fatty acid composition. This finding offers a dual benefit of reducing agricultural waste and emissions while potentially lowering production costs for dairy farmers.
