A blade of grass emits the same amount of compounds regardless of where it decomposes, whether in a cow's stomach or the fields were it grew and died.
Just. Stop. With the "Cows are gonna cause global warming and kill us all" line. That cows eat and concentrate the emissions due to decomposition makes no more or less emissions compared to millions of blades of grass decomposing throughout the millions of square acres of grass fields. It is still just dead grass decomposing.

She said that it's important to note that methane is not released by the cows themselves, but the bacteria in their gut. Similar bacteria also exist in the environment and produce methane in wetlands, rice fields and landfills.
The actual amount of methane released from a single blade of grass wouldn't change if it was just left to decompose, or if it was eaten by a cow and then digested by the bacteria in their gut.
