Currently, regulators assume that a cow produces 12.8 pounds of volatile organic compounds,VOCs, a year.
But regulators, environmentalists and many in the $4 billion dairy industry agree that the current emission factor, which is based on a 1938 study, is out of date.
It has been proposed to increase this to 20.6 pounds per cow. Industry groups estimate that number is around 5 pounds.
..............................
FYI...the 12.8 pounds per year comes to about 16 grams per day.

The 24-h CH4 emission per cow can be about 400-700 L (587 ± 61.3 L per day)
Good question! microbiology, global warming, plus slight humor ;-)

I don't know about one cow, but cows in general are a significant source of methane, a global warming gas. And that's just the cows - add in the pigs, and the droppings from poultry....
