Researchers Toilet-Trained Cows In Hopes of Reducing Their Greenhouse Gas Emissions (gizmodo.com) 78

An anonymous reader quotes a report from Gizmodo: Researchers in Germany recently demonstrated that cattle can be toilet trained to reduce some of their climate impact. By having the young cows pee in latrines made of turf, the team of experts in animal behavior and agricultural science stopped the natural production of nitrous oxide from the cow's urine. Cows are notorious for their contributions to greenhouse gas emissions in large-scale farming; the animals belch (and to a lesser extent, fart) methane, and their urine and poop combine to produce ammonia, which isn't a greenhouse gas itself but is converted into nitrous oxide by microbes in the soil. The team trained nearly a dozen calves to urinate in a makeshift latrine, nicknamed the MooLoo, thereby stopping the urine from becoming part of the problem. The research was published on Monday in Current Biology.

Training the cows was a fairly simple process on paper. First, the scientists penned 16 of the animals into the latrine area. When the cows urinated, they were given food or sugar water, tacit endorsements of their decisions. The next step was teaching them not to pee in the pasture, which the team did by implementing an unpleasant stimulus whenever they did so. That stimulus was originally a loud noise, but when the researchers realized the animals didn't mind it much, they swapped it out for spraying the cows with water, a relatively harmless message of "bad cow." The team found that the cows' ability to hold it and go in the latrine was equivalent to a child's ability with the toilet -- even superior to that of young children. [The team] hopes to bring the latrines to other sites and increase the number of potty-trained cows. "To do this, we must first automate the whole training procedure and adapt it to the conditions on the farm," he told Gizmodo in an email. "We want to tackle this in a follow-up project."
The report notes there are a couple of limitations with this effort. "First, not all of the cows could be potty-trained. Only 10 of the 16 calves quickly learned to pee in the proper place and could routinely reproduce that action," reports Gizmodo. "That's trouble for anyone trying to scale up the practice (there are more than 1 billion cows on Earth). Second, the experiment didn't cover defecation, and cow poop also contains ammonia. There's also still the major problem of methane, a greenhouse gas 80 times more potent than carbon dioxide, tied to cows burps and farts."

    Without this fantastic research, we may have finally solved the riddles of interplanetary exploration. This opens up the possibility that man and moo can now comfortably travel the stars together.

    First, this increases the choices of space food available, so that it isn't only impossible burgers for the rest of time.
    Second, there will be an unlimited supply of methane so that no one ever gets stuck on an asteroid.
    Third, there will be enough ammonia to run the cooling system forever.

    Mooniverse, look out now!

      Burps more than farts. But, yes, cows cause about 14% of global warming.

      No, that has little to do with it. Cows burp the most methane when grazing on pasture.

      attention shifting away from the abuse these animals go through all of their life in "factory farms".

      That makes no sense.

      Why would the beef industry distract people from factory farms by ALSO blaming their industry for global warming?

      It gives people yet another reason not to eat beef.

      Chicken and pork are produced with much less GHG emissions than beef. Tofu is even better.

      • If cows are responsible for 14% of global warming, shouldn't we rather eat them instead of becoming vegetarians? I mean those people are so aware of the problem but entirely unwilling to help solve it...
      • More seriously, did the total cattle population grow by so much, that the methane now is 14% of all agw? Because if the cattle numbers didn't increase, the methane they create is constant per year, and the breakdown is also constant (10 years half life?), so effective it's a static balance iff the life stock number is stable.
    • by tragedy ( 27079 )

      It's not so much the farts, it's the outgassing from cow manure after it's left the cow. Hence why you can reduce it by toilet training the cows. You do have something of a point about silage and other things cows are fed. In theory the practice of feeding them ground up cows has mostly been stopped, but I'm not completely sure. That should have obviously been a recipe for disaster right from the start.

      Yeah science is stupid, we should go with angry opinions.

      Well except your stupid addition of "destroying the world" in order to discrete the other position by falsely painting it as extreme.

      Cows use methanogenic bacteria to digest cellulose. All ruminants do including wild ones on completely natural diets.

    • They feed them grain instead of grass. Whats worse is when vegans try to use this example to force veganism on everyone else. Do you know what it takes, in absence of actual meat, to get your full profile of amino acids? You must consume both grains, and legumes. BOTH are notorious for creating methane in humans. So lets blame the farting cow, and instead create 4 BILLION constantly farting humans. That will fix everything.

    Years ago, someone reported that you can sinificantly reduce cow's greenhouse emissions simply by feeding them a bit of seaweed or something like that. It seemd super easy and effective and cheap.
    Whatever happened to that?
    • Yea, I remember this too, but apparently this was completely suppressed and covered up... You only had to add little bits of seaweed to their current food too, but my guess is the world is more corrupt than any of us could ever imagine and the Governments don't actually want a solution to global warming for whatever reason. Plenty of speculation as to why, but your guess is as good as mine...

        The seaweed was for methane production, this article is about nitrous oxides.

        It wasn't covered up; the initial study was in 2014; the long term study finished this year. That's important, because the initial study (Abstract mentions 72 hours) suggested 'up to 99%' reduction, while the long term study (147 weeks) is saying 'up to 80%', still huge, mentions no distinguishable taste difference, and it will change the food we feed cows. Considering the first thing that pops up when searching "cow" and "seaweed" is a dozen articles on it, I don't think anything has been covered up. Farmers don't just switch like a lightbulb when a study comes out; they need to know long term effects on their animals. Need to know which seaweed, at when concentration is healthy, a lot of things.

    • Yeah, that sounds like a good idea. Not sure if cows like seaweed - they had no problem eating the dead cows though. Remember remember the mad cow disease?

      It looks like this is still being actively studied and shows a lot of promise [ucdavis.edu]. The article says they were testing whether or not it changed the flavor of the beef (apparently not).
    • Grass fed beef does not have the methane problems, and the meat is leaner, healthier, and tasted way better than its grain fed counterpart.
  • Cow piss and patties are powerful fertilizers, that the farmer does not have to buy. In a lot of marginal farmland, topsoil can be barely 1cm thick. The urine fertilizes the ground with grass or subclover, stopping the soil blowing away. Ever seen a duststorm 1000miles away drop red soil on you vehicle/house. That urine then causes grass, which absorbs nasty carbon, and releasing pure oxygen. Ok, you capture the pee? Now what do you do with it? Meanwhile in the UK, farmers are replanting hedgerows, to rees
  • Always blaming cows, as if they are the only source of these emissions. *All* ruminants belch methane, yet you don't see headlines clamouring for the reduction in, say, sheep numbers (there's more than a billion of them as well)...

      From TFS and TFA, the gas at issue is nitrous oxide, not CO2. In any case, plants take in CO2, cows eat it, then fart out methane which is more short lived but more potent than CO2. And also, the only inputs to raising cows aren't grass and air, but also shelter, warmth, vets, feed, distribution of feed, and potentially fertiliser to produce that, which have a carbon input. Many cows sadly never see a blade of grass and the feed is hauled to them using fossil fuels and made from crops that required fertiliser and irrigation.
      • All true. But so far any alternative that has been well explored is worse than the cows when you consider that full picture which also needs to include the highly limited resource which is fresh water.

              For agricultural use diesel in the UK is zero-rated for duties, but is coloured and using it for domestic vehicles is outlawed. Other schemes operate across Europe. There aren't the large areas devoted to maize or subsidies for it to be converted to ethanol.

    • Methane has Carbon in it, so it's "neutral" in a embarrassingly simplistic way...

      Burning cows and their food into carbon is fine (no methane) as long as you don't do this at a rate faster than the earth can transform that carbon back into plants and cows again! Even if the exchange was "neutral" you'd have to maintain a balance in the cycle to not run into problems. I can use 1TB of RAM and it's all "neutral" and I never run out... But if I use that all at once, it's slow as hell as VM thrashes me so much

    • No cows are not carbon neutral in the environmental sense of the word. They emit methane which then stays in the atmosphere contributing to global warming by an order of magnitude more that CO2 for several years before the gas breaks down and would be reabsorbed by the plants.

      Over a really long term they are carbon neutral, but they contribute a shitton to global warming in the process.

    • Cows are carbon neutral. The carbon they release is entirely from the carbon they consume.

      Digesting grass (a solid) and producing methane (a gas) is not carbon neutral, in terms of atmospheric carbon. Your argument could equally apply to a coal-fired power station.

The net outcome of these various looks into the ecological impact of various solutions to the food problem actually shows that anything we did instead of raising cows would actually be more harmful, especially in terms of water usage and in most cases reduce ability to feed everyone. That is pretty significant since we fall drastically short of being able to feed the human population globally as it is.

      Indeed. Cows eat food that contains Carbon. During the digestion process, they convert some of that carbon into Methane whether via anal gas or burping, the carbon comes back out. Comes back out in their manure as well. Some is incorporateed into their bodiies as well. If the vegetable matter they were eating just decayed, the carbon would return through the atmosphere via rotting or oxidization,

      If Cows were eliminated, same difference.
