Cows That Burp Less Methane to Be Bred

Canadian scientists are breeding a type of cow that burps less, in an attempt to reduce greenhouse gases. Cows are responsible for almost 75% of total methane emissions, mostly coming from burps. Stephen Moore, professor of agricultural, food and nutritional science at the University of Alberta, hopes the refined bovines will produce 25 per cent less methane. Nancy Hirshberg, spokesman for Stonyfield Farm says, "If every US dairy farmer reduced emissions by 12 per cent it would be equal to about half a million cars being taken off the road."

For example, probably the greatest natural landscape for large grazing herd animals today are the Serengeti and Masai Mara plains. Combined, they only support 1.5 million wildebeest.

      Size of national herd, all cows and calves: 106 million.
      http://usda.mannlib.cornell.edu/usda/current/Catt/Catt-07-20-2007.txt

      But wait! Or, rather, weight:
      Bull bison (37% of herd): 1800-2500 lb.
      Cow bison (45%): 900-1200 lb.
      Calves (18%) :35 lb up to numbers above

      Weight:
      http://www.gunpowderbison.com/Kids%20Corner
      So the TONNAGE of natural ruminants on the North American plains can be calculated from the above numbers (giving calves half the average of cow and bull) to be an "average bison" weight of 1559 lb. Times 60M, is 46.8 megatons.
      The US herd is lighter because it's mostly younger than a natural one; we slaughter cows at 2 years, bison live 20, so a higher proportion of the total is calves.
      My first reference also notes that just 33M of that national herd is over 500 lbs. Conservatively giving them all the full adult weight (from wikipedia, "cattle") halfway between 1300 and 1900 lb, and the average of the other 74M that are under 500lb, conservatively, at 400 lb...we get a total tonnage of beef at 41.2 megtons.
      Bottom line: there are fewer tons of beef now than there were of bison in the 19th century. Beef eater's disturbance of the natural methane balance is zero, indeed it may be NEGATIVE.
      Maybe not; 41.2MT is only 12% less than 46.8MT and my whole-hour of research may have missed a few things. Also, the amplification of GHG output by the 10% of the herd that's on feed is a factor. I'm willing to call it even, although my weight numbers were quite conservative.
      So, there's no GHG impact at ALL, compared to the original, natural state. At least not in North America -- but what was the former methane production everywhere that are now cattle ranches? Most ranching is done where there was an equivalent animal before. And even swamps and rainforests have quite a bit of decomposition that produces methane.

However I need to take a moment to beat you over the head for that last nonsensical sentence that nearly removes any value from your post.

      Modern agriculture (ie Fertilisers, pesticides, Concentrated Animal Feeding Operations, antibiotics, posilac, et al.) is far "greener" than organic farming will ever be. I know this because I work in Agricultural research.

      Modern fertilizers and pesitcides enable greater crop yeilds/acre, meaning less acres need to be planted, meaning less acres need to be driven by tractors both harvesting & planting. Organic production actually requires you pull out the tractor and appy fertilizer and pesticides more frequently (Organic doesn't say you can't, it only says you can't use specific ones becuase without both no one would be able to grow enough organic corn to feed their organic chickens) becuase it forces you to use fertilizers and pesticides that don't work as well. It also forbids the use of roundup ready crops that require a fraction of the fertilizer and pesitcide applications and can be planted without tilling the soil.

      Tilling the soil is the single largest reason for nutrient leaching from soil into surface water when it rains. The tilling breaks up the soil, airing it out, and making it easier for rain to wash away important nutrients, thus requiring greater applications of fertilizers (See where I'm going with all of this?).

      CAFOs enable producers to manage larger heards more efficiently, with a greater attention to detail. Some one that works with weanling pigs all day every day will have a better eye for which pigs are struggling than a farmer that only spends part of their day with the weanling pigs, and the rest of the day spread across the growers, finishers, boars, 1st and 2nd parity gilts, sows, and the farrowing house. It's akin a doctor specializing in one particular field of medicine instead of forcing them all to be General Practitioners.

      Posilac (trade name for recombinant bovine somatotropin or rBST) enables farmers to use less cow, and as a result less feed, to produce the same volume of milk. That kind of math shouldn't really need explanation or defending, but the organic movement forbids the use of posilac, despite it being molecularly identical to the naturally occuring bovine somatotropin normally found in milk. Milk from these cows contain BST at the same concentration and cannot be differentiate from milk from cows not injected with rBST. The fact that tests have been done where rBST and purified 'normal' BST have been injected into human tissue and proved to be too dissimilar to interact with the receptors for human sotmatotropin seems not to faze anyone for some reason.

      Sub-theraputic use of antibiotics both prevents clinical, as well as sub-clinical infections and is primarily used in animals predisposed to infections due to stage of development (weaning comes first to mind). They also prevent the need to use much larger doses of theraputic antibiotics, and help animals grow more efficiently as less of the energy and nutrients in animal feed go toward growing bacterial populations and more goes toward growing the host animal. None of the data coming out of the EU in the wake of their complete ban of sub-theraputic antibiotics has shown any reduction in the prevalence or distribution of antibiotic resistance genes. My belief is that's because most people don't interact with farm animals on a regular basis, but they do go to doctors offices and hospitals where antibiotics are abused to a shameful degree (and all the bugs there can colonize humans, where many bugs that colonize pigs or chickens cannot colonize humans. The internal environment is too dissimilar.)

The problem is that a cow produces not just carbon in one form, it tends to produce methane (the burps referred to) and methane has a much larger impact in global warming than CO2. The reason that the cows produce large amounts of methane is because the bacteria in their rumen (first stomach) is not right for the diets of mostly corn and soy that they are typically fed and this produces the methane burps. (Incidentally that is why there is relatively little methane in cow farts, almost all of the methane is produced in the rumen.)

    So one option is to feed cows mostly grass, that is not sustainable in the large industrial scale used. Another option would be to genetically engineer bacteria that produces less methane and introduce it to the cow rumen. That actually makes more sense than engineering cows with a rumen more like a stomach. Another far fetched option would be to capture the methane, then sequester or burn it outright (the green house gases then are much less harmful).

    There is plenty wrong with our current system of agriculture. The environmental aspect of it can be dealt with by more informed farmers and consumers. We need to move away from Concentrated Animal Feeding Operations (CAFOs) and corn culture and towards sustainable local farms. The article states that animals should be fed a higher energy diet (i.e. corn). The energy costs of producing that diet are astronomical as compared to a grass fed diet. The number one energy cost in producing a lb of corn is the Natural gas it takes to make the synthetic fertilizer. Guess what, the extraction of natural gas is an major methane contributor.

    Lets put our focus on producing our food in a more sensible manner. People intuitively know that cows as a methane source is ridiculous hence the jokes. There are so many bigger environmental and ethical problems that we need to tackle in our food industry. Its these half truths get people side tracked away from the real issues. Go meet your farmer and make sure he's raising your food in a manner that you deem acceptable.

    Just because they burp less doesn't necessarily mean they produce less methane... "We made a cow that burps less. However, it farts more."

    If you read the article it states that it's not that they just "burp less" it's that they actually produce less methane.

    Ahh, the old "Global Warming is not caused by humans, or not happening" theory.

    Perhaps you'd like to explain why not one scientific organization has produced a convincing argument against the existence of global warming, while many other scientific studies have. The only possibilities I can think of that make your argument reasonable are some combination of:
      1. A vast conspiracy of climatologists made the whole thing up.
      2. Al Gore and some environmentalists cajoled and bullied the vast majority of climatologists into making the whole thing up.
      3. realcoolguy425 knows more about how the Earth's climate works than the vast majority of climatologists.
      4. There's some built-in bias that means that all climatologists are predisposed to seeing evidence of global warming when there isn't any.

    Feeding cattle different grass, ie something similar to what they evolved to eat, solves the methane problem.

    So other than making lots of money from selling a low-methane breed, I really don't see the point, we already have the solution to the methane problem, we were just feeding them wrong.

    Most humans are already predisposed towards the herbivore end, that's why we breed so many cows, rather than, say, bobcats.

    Well, as spokesperson for the National Bobcat Meat Council, all I can say is that you're missing out!

    For the consumer, bobcat is a wonderful choice. Bobcat is delicious, naturally lean, high in vitamins and minerals, and, let's face it, a completely awesome thing to say you are eating. Imagine you're in your backyard at your grill, talking to your competitive neighbor Bill over the fence. "Hey Bill, how's it going?" you say. "Oh not bad, just grilling up some pork sausage on my new 80,000 btu propane grill. How bout you?" Bill says. "Oh, not bad, slumming it with my measly 20,000 btu grill... making bobcat burgers!" Bill is stunned. "Oh wow! You are my king! I worship you!" he says in one of those awkward vaguely homo-erotic moments that seem to happen around Bill a little too often. But he is right -- bobcat is the burger of kings.

    And for the rancher, bobcat presents many exciting opportunities as well. For one, wolves and other predators will not fuck with your livestock. You can even put your pig or goat pens -- needed to feed the bobcats -- in the middle of the bobcat pens and provide the ultimate in protection for your herbivore stock as well! Also, if you're tired of complacent cows and the tedious and unexciting process of herding them for slaughter, well, you're in for a thrill! Any wannabe cowboy brand a cow, but come at a bobcat with a glowing red brand and get ready to prove your mandhood! Compare scars with other bobcatboys and see who really has what it takes! I had one rancher tell me that they were thinking of getting out of the business due to the lack of physical danger, until I took him on a tour of a bobcat ranch and one of the feisty rascals hiding in a dark corner nearly took his face off. Well I had him signed up that very day to start his own bobcat ranch!

    Okay... I'm not going to lie. Bobcat ranching is hell. They're mean, ornery, antisocial, dangerous, and have no compunction about going for the junk. The only thing that rancher signed was the out-of-court settlement with the National Bobcat Meat Council for his injuries. But seriously, I need to push these bobcat ranches or I'm going to lose my job. We'll even start you out with a bunch of free livestock! We're up to our fucking necks in bobcats, come on take some off our hands. They aren't even that tasty but god damn cut me some slack I'm trying to move product here. Eat some fucking bobcat already!

  24. Forgetting feedlots? by proselyte_heretic · · Score: 2, Informative

    High methane from cows is a symptom of the problem, which is that most beef is from feedlots. Not only is the huge amount of waste produced by the feedlots a large methane source, but also the fields that are used to grow the feed (mostly corn). This article (print version: http://www.motherearthnews.com/print-article.aspx?id=150244) explains that conventional feedlot agriculture emits carbon dioxide and methane both on the fields and the feedlots, while rotational intensive grazing sequesters carbon and emits much less methane.
