Clay Cuts Methane Emissions From Cow Burps by 30%
If you’re not aware, methane from cow burps significantly contributes to greenhouse gas emissions. However, a recent study suggests a potential solution: feeding cows clay can cut their methane emissions by more than 30%.
Yes, we are indeed serious about addressing cow burps.
Cows emit methane as a byproduct of digesting their high-fiber diet, which they release through continuous belching.
The United Nations Environment Programme reports that methane from livestock burps, including those of cows, contributes approximately 40% of global methane emissions. Methane is particularly problematic because it is about 25 times more effective than carbon dioxide in driving global warming.
From Fish Oil to Halloysite Clay
To address this issue, scientists have tested various feed supplements, including fish oil, seaweed, tropical leaves, and even baby kangaroo feces. Recently, halloysite clay has emerged as a promising solution.
In a pilot study led by Dr. Bhaba Biswas at the University of Newcastle in Australia, researchers discovered that incorporating a modified form of halloysite clay into cattle feed reduced methane emissions by over 30% within 24 hours.
Reducing Methane Production and Promoting Cattle Health
According to Biswas, the clay diminishes the activity of gut microbes and parasites responsible for methane production. The clay seems to be safe for the cattle, as they naturally consume small amounts of soil while grazing, and it may even offer health benefits such as reducing gut acidity. The clay is eventually excreted with the feces.
Further research is necessary, but there is optimism that the modified halloysite could eventually be available as affordable pellets or a spray for pasture application.
Dr. Biswas and his team will present their findings at the International Cleanup Conference in Adelaide, Australia, this week.
