Can Kelp Help? Research Examines Dairy Farmer, Dairy Nutritionist Attitudes on Adding Feed Additive to Cut Methane Emissions
While the majority of climate change research focuses on reducing and capturing carbon dioxide, less attention has been paid to methane emissions, despite the gas having 30 times the warming effect. Over a quarter of the United States’ total methane emissions are derived from enteric fermentation (cow burps) alone. Emerging research finds that feeding certain species of algae (seaweed, kelp or microalgae) to cattle can reduce their methane emissions by 80 to 99%. Unfortunately, most farmers and bovine nutritionists are unfamiliar with algae-based feed supplements, and the supplements are not always available and can be expensive.
