Kangaroo Farts: A Great Green Disappointment

Guest essay by Eric Worrall

Scientists researching the underlying reason for the low methane content of Kangaroo farts, with a view to reducing cow flatulence, have been disappointed to discover there is nothing special about Kangaroo gut bacteria.

According to The Guardian;

For some time, researchers intent on breeding less windy flocks and herds hypothesised kangaroos might have a unique mix of micro-organisms in their stomachs that produce less of the gas.

The hope was by transplanting these micro-organisms, cattle and sheep might produce less methane.

But new findings suggest otherwise, and should help refocus sheep and cattle research on alternatives that might yield results.

The experiment saw red and western grey kangaroos kept in comfy, sealed chambers, allowing researchers to analyse the mix of gases going in and coming out.

“We think that the methane is low because of the way food moves through the kangaroo stomach, and not because of a unique gut fauna,” study author Dr Adam Munn said.

You might think the next step in the battle to defeat the bovine methane menace, is a transgenic KangarMoo, a cow with the gut processes of a Kangaroo. The Guardian article sadly shies away from this fascinating possibility, and kindof peters out with some vague speculation about researching possible land use changes.

It actually is not if one understands chemistry, heat transfer and looks at actual data. see https://cementafriend.wordpress.com/2011/10/ The IPCC have no proof they just accepted this lie from individuals, in “green” groups, who have no qualifications but are good at spreading false information.

“Do kangaroo’s taste as good as cows?”
Use of apostrophe s to form plural is required only with lower-case letters, so watch your p’s and q’s.
Is a kangaroo’s taste as good as a cow’s? Use the apostrophe only to indicate possession. The horse’s gas will eventually pass.

Correction–

Form plural of any noun simply by adding s. That’s it.
The apostrophe is also used to indicate contraction, where it stands in for omitted letters.

There’s no need for the apostrophe to indicate plural:
My CDs have all been ripped. The CD’s contents included songs from the ’50s.
The only reason the apostrophe is used with lower case letters is to avoid ambiguity: p’s and q’s vs. ps and qs. There is no ambiguity with CDs, or DVDs,

Heh. Well, I woke up in the middle of the night realizing I’d overlooked a few more nouns that add es to form plural: bush bushes, wretch wretches, bitch bitches…you get the idea. In these cases, the word’s pronunciation will be your guide.
So let me try again: English nouns form plural by adding s or sometimes es, but almost never by adding apostrophe s.
Only in a very few special cases is apostrophe s required. Some writers may add the incorrect apostrophe in forming plural because they see others doing it.
Monkey see, monkey do.

The Judge’s forehead formed a frown.
“You stand before me, William Brown,
Charged with violations backed
By the Threatened Species Act,
To wit that you on April 2,
Did kill and eat a kangaroo.”
I did, my Lord, my plea is guilty.”
“I have in mind a heavy sentence
Unless you show me great repentance.
Something short of execution –
It’s too late now for restitution.
What say you to mitigate
The value of the roo you ate?”
My Lord, I beg to you for mercy.”
“The farm I had had copped the drought.
The roos ate all the pasture out.
I had no work, the kids no food,
I did what any father would
To save the life of kith and kin –
We ate the roo and tanned the skin.”
(His left eye shed a gentle tear.)
The Judge’s eyed were moist as well.
The level of his fury fell.
“In view of evidence presented,
Because you have so much repented,
I see no need to go beyond
A 3-month good behaviour bond.”
“All stand please”, the Usher said.
As William Brown walked out of court
His Honour said in afterthought,
“Before you go, and now you’re free,
Would you please describe for me
And learned counsel here too,
What is the taste of kangaroo?”
William Brown thought long and deep.
“Your Honour, it is hard to say –
Let me put it in this way.
On one hand it is flavoured rather
Like a freshly-grilled koala.
But then again, it has a touch
Of marinated platypus.”
“With leave, my Lord, my cab is waiting!”

Well for one they picked the wrong end (maybe they are just a wee bit smarter in New Zealand):
“According to researchers at New Zealand’s largest Crown Research Institute, AGResearch, up to 95 percent of the emissions comes from the cow’s mouth rather than its behind.”
But then here is the rel difference between the animals (and this on ehow yet):
“Although it consumes a diet similar to the cow’s and shares digestive similarities, such as two stomach chambers and cud-chewing, the kangaroo differs from the cow in that it produces almost no methane during digestion. As the kangaroo’s food ferments in its stomach, hydrogen is produced as a byproduct. Bacteria turn this hydrogen, not into methane, but into acetate, which the kangaroo then uses as energy. Scientists have considered introducing these bacteria to cow digestive systems in order to reduce emissions of methane”

“”According to researchers at New Zealand’s largest Crown Research Institute, AGResearch, up to 95 percent of the emissions comes from the cow’s mouth rather than its behind.””
You didn’t give a source, but I did find this:

Let’s start with how and why cows produce so much methane gas. Cows, sheep, goats, giraffes, and deer belong to a class of mammals called ruminants. Most ruminants have four stomachs, two-toed feet, and store their food in the first chamber of the stomach, called the rumen, before regurgitating it. This regurgitated food is called “cud” and the animals chew it again to help further break it down to make it easier to digest. Inside of the rumen, over four hundred different kinds of microbes exist that also play a critical role in the digestion process. Several of these microbes create methane gas as a byproduct. Due to the sheer number of cows on the planet, along with the large size per cow, our tasty friends produce more methane gas than all other ruminants combined.
[…]
In actuality it’s not as much the farting that’s the problem, cows’ burping and manure contribute more methane gas than flatulence. According to researchers at New Zealand’s largest Crown Research Institute, AGResearch, up to 95 percent of the emissions comes from the cow’s mouth rather than its behind. It’s estimated, through whichever orifice, that each individual cow lets out between thirty and fifty gallons of methane per day. With an estimated 1.3 to 1.5 billion cattle in the world today, this adds up fast.

http://gizmodo.com/do-cow-farts-actually-contribute-to-global-warming-1562144730
(my bold)
I don’t see anything on the methodology of this study wrt how the researchers were able to distinguish between gases vented from the front of the cow as opposed to those vented from the rear, but I suppose it was by process of elimination.

There’s no legitimate science behind this of course, there’s no way near enough methane in livestock farts to affect the climate in any way. This is all about restricting or removing our meat supply to weaken and sicken the population as a means of control, to remove resistance as they move toward a feudal world government and to make the population even more dependent on big pharma.
We all know the events surrounding Stan in South Park where he stopped eating meat and gradually small sores erupted on his body that grew larger and were found to be small vaginas. Stan had contracted vaginitis. Had he kept up with his vegan diet according to the doctor he was in danger of turning into one giant pussy.

November 5, 2015 9:17 am

It’s all meaningless drivel when you realize that methane and all “greenhouse” gases cannot detectably warm the Earth’s surface or atmosphere. These gases, at altitude are at -17 deg C and Earth’s surface is 15 deg C. Any radiation directed downward by the gases will be rejected and reflected by the surface and lost to space. A cold gas simply cannot warm a warmer surface. Methane and CO2 have half lives in the atmosphere of about 5 years, so this is a very dynamic situation. Study these animals to find out more about them but any efforts to decrease methane from them is a theft of research money, it’s a criminal waste of time, money, and resources.

Oh Nooo! claim the researchers! It Must be the bacteria! We will isolate the roos and measure the room’s overall gas contents…
For all they know, the roos might breathe in methane and release CO2.
Nor did they assess the droppings for digestive efficiency nor compare the intake to output for digestive absorption preferences.
When they get to the basics, are the digestive processes of a roo adapted to drier conditions better than domesticated bovines? Perhaps studying the digestive tracts of arid creatures would be better?

Yes, I had rabbits for years. They didn’t seem to emit much gas from either end, they were eerily quiet. Too quiet.
But that got me thinking. If somebody’s studying the gas emissions of ruminants by experiment, really the experiment should compare CAFO fed cows with grassy pasture fed cows. Cows didn’t really evolve to eat the complex mix of stuff that CAFOs supply to them, any more than we evolved to eat Mc Donald’s.

Studies have also shown great correlation between cow gut flora and diet. Cows are apparently healthier on grass, and of course, the grass digests differently than commercial cow-feed.
So, another relevant question about cow burps and farts might be “does it matter how they’re fed”?
Other studies have shown that grass fed beasts are healthier for people to eat, and the milk and butter have better nutrient value as well.

I’ve raised rabbits several times. I also believed that they were not gaseous; i.e. until my son came home from college with a pet rabbit.
There is a difference in animals raised as house pets versus farm animals kept and fed outdoors. Even when we raised angora rabbits, which require frequent handling, they were kept in cages outdoors.
Our new indoor pet bunny, Nina, was a spayed female who quickly owned the house, even my English Setter.
Nina quickly taught us that rabbits do sometimes have gas, perhaps frequently; but only occasionally is it potent.
One of Nina’s humorous traits was the look she would give me after a noxious gas cloud was emitted. I’d get the same look, no matter which of us dispensed the gas. After making sure I was saturated with her glare, she’d hop off with backward kicks emphasizing her dissatisfaction.

“…Studies have also shown great correlation between cow gut flora and diet. Cows are apparently healthier on grass, and of course, the grass digests differently than commercial cow-feed…”

That is simply not true.
Grass does digest differently, but after traveling through a number of stomachs, any vegetative foods eaten by a cow are well digested.
I spent a good part of two years working for a dairy farmer.
Milk is sold at quite ridiculously low prices. Cows produce copious milk, all day. Milking cows twice a day is a compromise and a minimum requirement.
As such, dairy farms can not afford expensive feeds. Most farmers allow their cows to graze as weather permits. Farmers also raise and harvest fields of grass, timothy and alfalfa. The easiest and cheapest to raise and harvest is the grass. Alfalfa may be a more nutritious higher protein food, but alfalfa requires harvesting just before peak flowering. All of these crops require drying before bundling into bales. Alfalfa is the fleshiest and unlike grass, it is not partially dried while standing. Just a couple of days of inconvenient rain and an alfalfa crop is ruined for cattle. Alfalfa is also a more valuable crop and many farmers sell all they raise.
One of the first lessons a farmer teaches is how to approach and handle cows. Cows are very routine oriented and are not fond of irregular or irresponsible activity. On my first trip through a cow barn, I noticed and asked about all of the brown stains on the wall behind the cow stalls. Many of these stains were five to six feet high, four feet behind the butts of the cows.
Now these cows were 100% grass fed cows. After I asked my question, the farmer Bob, looked at me and said that if I saw a cow’s tail lifting, that I would be a lot happier if I moved and gave the cow plenty of room.
This was obvious because most dairy cows are brought indoors for milking. Since then, I noticed many grazing animals from sheep and deer through elephants have similar explosive bowel movements. The elephant was best as onlookers surrounded the elephant; those behind the elephant were not happy campers.
A McDonald’s burger is actually quite healthful. A good mix of amino acids, protein, starches and fiber, if perhaps too much food for a meal.
Your concept of a CAFO is that of a large fattening operation run by corporations that process meat for urbanites and suburbanites. People that do not raise their own food and even complain when neighbors try to raise their own food.
Green Acres star ‘Eddie Albert’ was actually a true conservationist. He turned the front lawn of his California Pacific Palisade home into a small cornfield.
These CAFO as you refer to them are strictly short term places where cattle are fattened. Fattened by organizations that earn money from buying cattle and then feeding them high starch feed for weight gain before butchering.
Don’t like their business? Raise your own, or find a local butcher. I often buy a quarter steer from a farmer who is also a butcher. He not only raises cattle, but also farms. If demand is higher than his cattle herd can supply, he prefers to buy animals from the local 4-H clubs. Excellent quality animals raised by children learning husbandry. Most of these animals are raised as kings of the farm since the kids enter the animal in contests for best grown.
Arguing that meat is the problem is not a solution. Many of the grass crops, including forage crops like alfalfa are raised on land lying fallow or are poor land unsuitable for human food crops. If you’re insisting on the finest grown veggies, you are one of those who determines that land is unsuitable for human food crops.
Farmers operate on a desperately thin budget. Every inch of the property is raising one kind of crop or another. The recent push for ‘corn ethanol’ has caused many of the larger farms to literally plow to the edge to maximize crop and earnings.
Decades of true conservation organization work and efforts have been destroyed in a few years. These conservationists, mostly hunters, have worked directly with farmers convincing them of the necessity to leave edges and plots of land devoted to “Conservation Reserve Program (CRP) and the Conservation Reserve Enhancement Program (CREP)”. You’ll never see anyone from greenpeese or WWF talking or presenting to farmers information about these programs, yet these are critical for wildlife support.

“…Other studies have shown that grass fed beasts are healthier for people to eat, and the milk and butter have better nutrient value as well…”

That is false and falsehoods. Personal opinions masquerading as science is very typical of many promoting their pet lifestyles.
Selling organic began as a program in the USDA back in the 1960s and 1970s. Before the current POTUS, one could actually call up and review the original slideshows used by USDA to bringing farmers into selling organic foods as a niche product. Same crops, higher prices. Organic is a personal choice that is completely devoid of any difference to health.
USDA, (United States Department of Agriculture), is responsible for maintaining the ‘Nutritional Database’. If you want the absolute accurate facts on foods, you’ll find it in this database.
Eggs, a favorite discussion.
Organic, another favorite topic. Searching the food database for ‘organic’
Pork One of the few papers on organic meats.
The term ‘Organic’ is a marketing term, tool and ploy. The ploy is to sell the same product at higher prices. Yes, there are differences in how the crop is raised, but generally the cost differences favor certain crops being organic raised, branded and sold for a higher farmer profit.

Would it be safe to milk Kangarmoos? The “Kangar” part has a nasty kick! Is our milk supply in danger?

Why not just eat the kangaroos then? Get the government to remove the legislation restricting killing them. Get rid of govt tags and let an industry develop. The roo numbers in rural areas of eastern Australia are insane, wth more roos to the acre than sheep in large areas of the country. They are excellent lean meat, very well adapted to the environment. They produce top quality thin tough and flexible hides (ask any leather plaiter, blame Beckams wife for pressureing Nike to stop using it in shoes).
Eat the roos instead is such a simple and obviously green solution that they hate it.
Main reason is that it is not politically correct to do the screamingly obvious.

as I wrote above..there IS legal roo meat supply but there could bee a lot more.
on farm you can cull excess but are supposed to shoot n drop n leave
like the morons ruled on feral goat culls
odd thing is leaving high nitrogen corpses near native plants…kills the plants!
the proper Greentard solution would be use as pet meat n hides for leather on roo n goat
the tapeworm/Hydatids is the ONLY problem with wild roos
do not EVER cook it as suggested here;

Marcus…it may have no fat…but it is a good eat, try it but do not cook it like a steak. You then may as well eat a used tyre. Basically cook it “blue” or rather just show it the flame.
==============================================
oil or butter the pan properly!!!! and COOK IT THROUGH tapeworm in humans isnt pleasant, Hydatids is a whole load of grief…really!
like Deer theyre liable to stress panic and muscle breakdown following, so dont make for easy herd management as captive.

I never said *WILD* roos. WILD anything has many similar problems too. Pork of years ago, you had to cook it to death. Not so these days, you can cook it “pink”. Properly farmed/supplied roo CAN be cooked rare. I do it all the time…and I sure don’t have worms.

I hope to bring in a patent intended to reduce the harm resulting from the cow’s farts that as everybody knows is containing a high percentage of methane. Indeed this highly efficient greenhouse gas may be burnt and converted into carbon dioxide, a much less dangerous greenhouse gas through a simple device placed close to the cow’s anus, with a gas detector that will trigger a piezo-electric spark to set the fart ablaze as soon as it exits.
I am looking for funds to develop a prototype.

Seriously though, in my country the government has comissioned university research for ways to reduce methane from cows and sheep. Havent herd (pun) how they have got on yet though, but I bet the universities are enjoying the budget.

I have it on good authority that geneticists are hard a work on a “cowroo”. Milking an animal that leaps into the barn rafters may present problems. I designed a cow-fart afterburner years ago, but my research was terminated after it cost my uncle a perfectly good barn. Also lost a couple of cows to low earth orbits, thanks to a “delayed ignition” glitch I could have solved, given more time.

Now if erudition and humor were grass we would have an endless supply of hamburgers and ice cream here.
But these environmentalists know a little more about cows than you do.
Have you ever asked yourself, “How does that bull reach 2,000 pounds in just three or four years? Are they not vegetarians, eating grass and grain? That is a lot of protein in a short time. Also milk has a lot of superior proteins, so where does it all come from?”
The cattle are not only using the microbes to break down the food, but they also then move them to the next stomach and digest the microbes themselves. It is a stunning fact of symbiosis. The bacteria that help the digestion of food in the rumen/first stomach use simple nitrogen compounds to build proteins in their cells. The ruminants then digest the bacteria. This is the source of the proteins in the cow’s diet.
So a change in the stomach microbes used by cows will more likely than not starve the cows to death. They will not reach their full size nor produce the meat and milk they did before the microbes were altered by the environmentalists. And whether this reduces the methane emissions or affects weather patterns on earth I will leave to the people with the proper scientific paradigm to model, but I do know that the destruction of cattle would fit the vegan/vegetarian psychotic manias that the Cannabis Generation attempted to foist on the me.
As the next generation, I hate to have to be the ant at the picnic. But this is a profoundly fiendish environmentalist plot against the bacteria cows digest for protein. And foithermore, only the most spoiled rotten, corrupted generation that ever walked on the face of God’s green earth would ever, ever even think anything like this.

Steve P says, “The lead author got his Bsc in 1996. He looks remarkably young for a hippie.”
He clearly has a very long road in front of him if he ever wants to disabuse himself of Boomer philosophies! It can be done however. All it takes is a decade of life experience and hitting the books for every decade one was under the educational influence of the Cannabis Generation as a youth.
It is a monumental and lonely task to straighten oneself out, but personally rewarding.
So all I am requesting here is this: let’s not all pretend we have never seen science used for extremely negative vegetarian/vegan/organic-only/local only activism before. It’s been going on for decades now. The outcomes will certainly be destructive and catastrophic — but starving cows by altering their rumen bacteria is a truly low and slinking and revolting plan, even for hippies and their fresh-faced followers.

Wikipedia has a long article on The history of vegetarianism, which begins:
The history of vegetarianism has its roots in the civilizations of ancient India and ancient Greece.
While it is true that the Baby Boomers are getting up there, I don’t think we go back quite that far.

I would propose that it’s not the flatulence of an animal that creates methane, as much as its dung. This is a more continuous source which takes some time to dissipate. Does kangaroo dung not emit CH4 as it rots?

Actually the problem is climate researchers. I could show you a graph that maps the increase in methane and CO2 in the atmosphere against the number of climate researchers. Virtually a straight line. So obviously the climate researchers are causing the increase in greenhouse gasses.

In truth, it is microbes in the animal’s digestive tract which produce the methane. Apparently, in cows, most of this methane-producing microbial action takes place in the rumen, whose contents are regurgitated as cud to be chewed again.
The question arises: is the cow’s moo also the cow’s belch? If not, could any of the cowboys or cowgirls here provide further information on the cow’s belch, including transliteration into English.
Thanks.
