The worldwide race to quell livestock belching is on! Earlier this month, New Zealand researchers came one step closer to developing a vaccine that would reduce the methane emitted from belching livestock. Ruminant livestock burp and fart significant quantities of methane -- a powerful greenhouse gas that contributes to climate change. "Our agricultural research organization ... was able to map the genome ... that causes methane in ruminant animals and we believe we can vaccinate against [that]," said New Zealand's trade minister. On Tuesday, Japanese scientists said they demonstrated that oil from the shell of the cashew nut may cut by some 90 percent the methane emissions from cattle burps when mixed in with their feed. The cashew-derived cattle-belch suppressant could be on sale within four years. If it takes off, the technology could be a real cashew cow! Ruminants are responsible for about 25 percent of methane emissions in Britain as well as some 90 percent of New Zealand's.

We need to ask more specifically what this cashew supplement actually does. Given that ruminants fart, farting should be understood to be a natural element in their life cycle. A food additive that suppresses farting might very well be unhealthy for animals who naturally fart a lot.
I do not know that that must be the case, but it is a possibility; and we should inquire into that. On the basis of these very short articles, one gets the impression that (as so often!) the cattle are being treated as no better than food-producing machines, not as sentient creatures for whose health and well-being their human caretakers are responsible.
It might also be the case that the feed that has been given to these NZ cattle causes them to fart more than would a diet that is more naturally desirable for them. In that case -- and quite consistently with other complaints raised regularly in Grist and Gristmill about the way animals are treated in the meat industry -- , there would be yet another problem associated with raising cattle for food.

The more you eat, the more you...emit carbon?
Check out a funny and irreverent take on this New Zealand story and a whole host of other eco-news at TitanGreens.com. We love you Grist and good luck with the fundraising!

Anyways, I spent about $3 on the research/development of this gadget. If any of you want to lend me about $10,000,000, I'm sure I can fine-tune it so that it is more animal-friendly. They'll probably spend way more than that on developing a vaccine so I'm sure we could easily out-do the competition and monopolize the market on lowering cow methane emissions.

While your sentiments re not wanting to harm cows are laudable, there are other factors that should take priority. First and foremost, cattle are non-native, unnatural animals (they were bred by humans from water and cape buffalo) and they do great harm well beyond their methane emissions. The best thing that could be done would be to stop breeding them and eat the remaining ones. Meanwhile, concerns about individual cows need to be placed well behind concerns for the natural environment, including concerns about global warming.
So, you should begin marketing your invention immediately. If a few cows' rears get scorched, meat eaters can just have a barbecue.
