Sealing manure ponds at a Central Valley farm led to a significant reduction in emissions. A large, balloon-like tarp covers ...

The federal government revises the feedlot industry's contribution to greenhouse gas emissions after adopting a new equation to calculate methane from grain-fed cattle burps.

Methane is a naturally occurring gas that comes from a variety of biological and industrial sources, from oil- and gas-well leaks to decomposing garbage to, well, cow burps.

In an attempt to recycle the water in the lagoons, two local scientists — Keith Cameron and Hong Di — began testing the ...

Cattle and methane. ... However, 97 percent of all the methane gas from a cow is actually released by belching rather than farting, according to the United States Dairy Council and NASA.

Learn more about the process some dairy farmers are using to capture methane and turn it into renewable natural gas.

But in digesting the fiber, the microbes emit 30-50 quarts of gas per hour into the cow’s stomach. Feeling bloated, the cow belches the gas–which is overwhelmingly methane–to relieve the ...

In total, the livestock industry is responsible for between 11.1 and 19.6 percent of global greenhouse gas emissions, and cow belching is the biggest contributor to that number.

A heifer stands inside a methane chamber at Cornell University, June 7, 2024, in Ithaca, New York. Researchers are studying how to reduce methane emissions from dairy cows. Melanie Stetson Freeman ...

Methane is a powerful greenhouse gas, and cows are a major source of it. A group of scientists is developing a proof of concept for a vaccine that would curb methane emissions in cattle.

For decades, scientists have been working on a methane-reducing vaccine for cows with little success, until now. A prototype vaccine by US-based start-up ArkeaBio, in partnership with Aotearoa's ...
