cloned beef

anagallis_arvensisFull Member
Offspring of clones illegal for meat in UK, can be used in other EU countries. So this guy in Scotland who has second generation clone stock could export to other countries and then the beef could come back via processed meat. What are peoples thoughts on this.
Animal welfare issues are my concern how many animals are born with problems and die young?
joe@brookscyclesFree MemberThey die young due to being beef cattle. Nothing to do with cloning.

No I'm talking about how many die or are born abnormally in cloning itself
higgoFree MemberNo I'm talking about how many die or are born abnormally in cloning itself
How many do?
thebunkFull Memberscience will solve all our problems:
mmmm….. artificial meat vats…..philconsequenceFree Memberi've got no problems with eating cloned beef, i'd eat horse, dog, cat if they were available like in other countries. i'd eat human if i had to (southerner of course, the northerners meat would be too fatty and full of "real beer" 😉 ) .
anagallis_arvensisFull Memberno expert myslef but a quick google came up with this
Reproductive cloning is expensive and highly inefficient. More than 90% of cloning attempts fail to produce viable offspring. More than 100 nuclear transfer procedures could be required to produce one viable clone. In addition to low success rates, cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders. Japanese studies have shown that cloned mice live in poor health and die early. About a third of the cloned calves born alive have died young, and many of them were abnormally large. Many cloned animals have not lived long enough to generate good data about how clones age. Appearing healthy at a young age unfortunately is not a good indicator of long-term survival. Clones have been known to die mysteriously. For example, Australia's first cloned sheep appeared healthy and energetic on the day she died, and the results from her autopsy failed to determine a cause of death.
In 2002, researchers at the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts, reported that the genomes of cloned mice are compromised. In analyzing more than 10,000 liver and placenta cells of cloned mice, they discovered that about 4% of genes function abnormally. The abnormalities do not arise from mutations in the genes but from changes in the normal activation or expression of certain genes.
Problems also may result from programming errors in the genetic material from a donor cell. When an embryo is created from the union of a sperm and an egg, the embryo receives copies of most genes from both parents. A process called "imprinting" chemically marks the DNA from the mother and father so that only one copy of a gene (either the maternal or paternal gene) is turned on. Defects in the genetic imprint of DNA from a single donor cell may lead to some of the developmental abnormalities of cloned embryos.
strikes me as not particularly good in order to make cheap beef, if the clones were being used for something that might benefit medical science I would agree, but not for beef. Farmers have been able to produce good healthy beef of an appropriate standard the old fashioned way or with stored sperm.
molgripsFree MemberThe cows in question are not cloned, one of their ancestors was. Is this not the same as just eating the offspring of the original donor cow?
I do not think it was done as a way of producing meat, rather an experiment, and they just ended up with a cow that presumably was sold the normal way?
scaredypantsFull Memberyou're laughing if you like to eat brains – most of these cows have at least 2 heads

Yes but IMO the animal welfare issues are huge, the meat is no doubt very good.

"However, the technology may never become economically viable for large-scale production of calves."
An amazing complicated and expencive way to make dog food.
molgripsFree MemberYes but IMO the animal welfare issues are huge, the meat is no doubt very good
Eh?
anagallis_arvensisFull Memberits fairly easy molgrips read what I posted above, think hard and then try reading it again. If that fails I've picked out a key part for you below:
About a third of the cloned calves born alive have died young, and many of them were abnormally large.
PeyoteFree MemberI suppose the question in this particular case is therefore: Do the offspring of cloned cows suffer similar infant mortality (and similar) rates if they are conceived 'naturally'?
If the answer is "No, they revert to the same rates as uncloned cows" then there are no additional issues that arise. If the answer is "Yes, they continue to have abnormally high death rates, often with unexplained causes" then there are most definitely animal welfare issues. Does anyone know whether this is the case?
About a third of the cloned calves born alive have died young, and many of them were abnormally large.
This isn't very useful as it seems to refer to cloned calves only, rather than the offsrping of cloned calves.
deadlydarcyFree MemberAnother addition to the long list of shite meat eaters will shove down their gobs.
anagallis_arvensisFull Memberwhats the matter molgrips cant you read or something?

Well I prefer to take a more longsighted view of animal welfare, its not just the animal that is on my plate that bothers me, but where that animal and its ancestors come from. Its rather like the argument that its OK to have animals in zoo's if they were born in zoo's which has always seemed a little odd me.
molgripsFree MemberHang on a minute, I don't think I quite follow.
Is cloning being used on an ongoing basis as a beef production technique? Or are there cows that were cloned for scientific purposes then entered the food chain. If the cloning is not continuing, then there's no issue since subsequent cows were conceived in the usual way. If someone is cloning cows for the beef market then that is bad.
And leave off the 'stupid' insults, I'm getting enough unfounded nastiness from Shibboleth on the tattoo thread 🙁
I'm not stupid, and I do care about animal welfare.
anagallis_arvensisFull MemberHang on a minute, I don't think I quite follow.
clearly
anagallis_arvensisFull MemberYes because some farmer is trying to grow beef in scotland using offspring from cloned animals
molgripsFree MemberRight, but is the cloning continuing or is it something that has already happened (perhaps for some kind of research purposes) and is not happening any more?
anagallis_arvensisFull MemberStill happening but not in the UK. Progeny of the cloned cattle have entered the UK and the UK food chain
molgripsFree MemberTo be honest I'd be happy for Europe to fall behind the US if it means we don't end up with giant factory beef farms like they have there.
PeyoteFree MemberWell I prefer to take a more longsighted view of animal welfare, its not just the animal that is on my plate that bothers me, but where that animal and its ancestors come from.
Fair enough, the problem is, how far back do you go? I'm pretty sure cows in their current form aren't how 'nature' intended. The whole industry has arisen because of the desire to breed animals for a specific purpose, in many cases this is to the detriment of the individual animals welfare. So, what do you do? Go vegan and cease to be a hypocrite? Or take a more pragmatic approach and try to make sure the animal products you buy are sourced from the more humane farms?
I tend to fall into the latter category, but then I don't have a problem with being a hypocrite (I tended to view it as a spectrum, rather than black and white!).
So, what all this boils down to is. Are these cloned cows and their offspring treated well when they're alive? Are they killed quickly and with as little stress as possible? If so, I'm happy to eat 'em!
Its rather like the argument that its OK to have animals in zoo's if they were born in zoo's which has always seemed a little odd me.
I think that depends on the animal, some animals (birds of prey) appear to 'imprint' themsleves on their carers and would be in considerable danger if they were to be released. Others are kept for their own protection (ironically, mostly because we're their major predator). It's a bit of a generalisation to keep animals in zoos just 'cos they were born there. I'd be surprised if that was most zoos policy.
molgripsFree MemberReleasing animals into the wild from zoos is a long and expensive process.
anagallis_arvensisFull MemberSo, what all this boils down to is. Are these cloned cows and their offspring treated well when they're alive?
Its not though is it, what it actually boils down to are how many aborted feotuses, deformed calves and sickly calves were created to make the one good clone

woosh, there goes a missed point
molgripsFree MemberI agree with you AA that cloning would be an (even more) egregious way to get beef. But I don't think that's what's happening, certainly not in this instance.
PeyoteFree MemberIts not though is it, what it actually boils down to are how many aborted feotuses, deformed calves and sickly calves were created to make the one good clone
Yes, but as I said how far back are you willing to go? How many aborted feotuses, deformed calves and sickly calves have been created since humans started manipulating the cow as a species? Genetic modification in it's current form shouldn't be viewed separately to how it's previously been done, i.e. species cross breeding and artificial selection.
woosh, there goes a missed point
Humour me then, because your point was too subtle for me to pick up on! What was the point you were attempting to make?
molgripsFree MemberI did read that, hence my comment about wanting Europe to stay behind the times…

good boy well done 😆
How many aborted feotuses, deformed calves and sickly calves have been created since humans started manipulating the cow as a species?
a **** sight less than a 1/3 thats for sure and thats only of the ones that were born alive!!!
Humour me then, because your point was too subtle for me to pick up on! What was the point you were attempting to make?
the point was that just because something is right with the current generation (bird of prey born in captivity orsecond generation from a clone) it does not mean the ethical issues associated with the previous generation should be ignored.
PeyoteFree Membera **** sight less than a 1/3 thats for sure and thats only of the ones that were born alive!!!
Really? Since humans have started breeding animals for their own ends I'm not so sure the mortality rate hasn't been that low. Of course I'm speculating here (as are you for that matter) we can't possibly know how many died in the early days of farming. It started before recorded history after all. So I suppose your hyperbole could be accurate.
Either way though, you're still discounting the many billions of lives that have been lost prior to cloning coming on the scene, not to mention the associated pain and suffering that went along with it. Seems a bit odd to focus on the (relatively) few that have been lost since cloning arose.
the point was that just because something is right with the current generation (bird of prey born in captivity orsecond generation from a clone) it does not mean the ethical issues associated with the previous generation should be ignored.
Oh, okay. I agree with that, but your argument still seems to stop after a few generations prior. Surely you should be arguning all the way back to the point that humans started getting involved with farming animals, and manipulating their genetics to their own ends? I don't understand the arbitrary point you're starting at, unless you object to the cloning process itself, rather than the idea of genetic manipulation?
GEDAFree MemberThe whole point of the cloning is to take cattle that have a really good dead carcass and then clone it to breed with those desirable genetic characteristics but can't be done naturally as it is already dead.
As the whole point is to get genetically superior cattle from a breeding and meat point of view why would you want to breed sickly or deformed cattle? If it works it works. If it breeds deformed or weak cattle farmers will not use it.
