Scientists seek miracle pill to stop methane cow burps

Raw Story  

by Julie JAMMOT A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas. "Almost half of the increase in temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis. - 'Social critters' - A researcher demonstrates how he samples cow stomach fluids while studying ways to reduce methane emitted by cow burps AFP Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production. "We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab. - More productive cows - Associate Professor Matthias Hess demonstrates a bioreactor used to study reducing methane emitted by cow burps at UC Davis in California AFP The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute.

UK virology lab developing ‘cow fart’ vaccine to reduce methane emission, fight global warming

Firstpost  

Cows primarily release methane through belching and flatulence, contributing to global warming. Researchers at the UK’s Pirbright Institute are developing a vaccine to reduce these emissions, supported by a $9.4 million grant from the Bezos Earth Fund. The goal is to create a single-dose vaccine administered early in a cow’s life to cut methane emissions by at least 30%. Some …
