My farts and burps have disappeared on this diet. Is it the same for cows?

Whose job is it to check for cow farts anyway?

Fun fact, it is those farty beasties, who are ironically our best bet at reversing global warming by chomping on the grasslands and compacting the snow underfoot to prevent melting. Mother earth is about to let out one hell of a methane cloud up in Siberia (if Sergey Zimov is right, and the permafrost melts much more there are going to be clouds of methane released into the atmosphere that will overshadow all the cows, landfills, and industry put together). Cattle drive to Siberia anyone?

FALSE; grass fed cows produce more methane.

This doesn't answer the question; also, it's unnecessarily rude. Everyone starts out a "noob."

Soccertanker, are you proposing that if cows went cannibal and started eating each other, the world's atmosphere would be saved?

Soccertanker -I think you should clarify your question. Especially the title, that is -if you want any real answers.

Matthew, I'm simply wondering if switching cows to their ancestral diet will have similar effects as switching us to our ancestral diet.

Is this methane situation a real environmental problem?

More grass = more ferementation = more methane.

Are you eating 100% grass?

Yes, grass fed cows produce less methane. It has something to do with their omega-3/6 ratio, so they're even trying to give cows in CAFOs fish oil.

See for example http://www.motherearthnews.com/sustainable-farming/grass-fed-cattle-zm0z10zrog.aspx

EDIT: After Jay mentioned it's the other way, I did some digging and it seems he's right.

In new zealand where cows are are almost entirely reared on grass there was talk of making farmers buy carbon credits to offset the methane production.
