[Closed] cloned beef

If in the beginings of farming and cattle breeding a 1/3 of all cattle died before reaching maturity I doubt we would have continued farming them because people would have starved to death, remember that number doesnt include the ones that were born dead or failed to be carried full term....

Oh I don't know. In the beginnings people didn't eat the same quantity of meat as we do now so higher death rates would be more acceptable. Maybe cattle were a luxury item back then, maybe there primary diet was vegetable, or game meat based. Who knows. Even so if 66% of their cattle did survive they'd hardly starve to death.

I used to live on a farm with beef cattle if you lost one in a hundred calves born alive you'd consider yourself unlucky.

Well, it's obvious you're coming at this from a more knowledgable perspective about the industry than me, naver having been involved in it.

not quite a third!

True, but that only goes back to 2002! Not exactly representative of the thousands of years that we have been messing around with cows is it?!

I think that there is a danger of this thread confusing cloning with gene manipulation. The aim of cloning, as GEDA pointed out, is to be able to recreate, many times over, a single prize winning beast. In this way when breeders produce a particularly high quality beast that single animal can be recreated many times over. The aim of this is to produce many beasts of the highest quality for consumption, not for them to be used in turn for further breading.

Ah, okay. I'm comparing apples with oranges then. My mistake.

So, this begs the question why are the death and deformity rates so high and can they be reduced? Clones should be genetically identical to their parent so why is it that these mutations are occuring? Could it be a similar mechanism to that which causes cancerous cells to mutate? If so there may well be interesting medical aspects to learn from this too. Which I suppose puts a whole new ethical/moral spin on it!

Cloning afaik takes the cell nucelus and propogates it. There's more to DNA than just the cell nucleus however (mitochindrial DNA) and there's also more to an individual than just the DNA. DNA is the design, but the implementation can vary on a host of factors.

Seems to me there's plenty of room for complex and as yet unknown interactions between nuclear DNA, mitochondrial DNA and the developing environment.

Hi Peyote, the other part of my point is that I simply do not believe that the death and abnormality rate for calves produced by these cloning methods is anything like what a_a has suggested. I too am from a farming background and a death/deformity rate of anything like 1/3rd would be horrific and no farmer would want to be involved in it. The farmer in Scotland had a herd of 92 healthy heifers in his fields, no suggestions of high death rates or deformities. I suspect that a_a is predisposed to assume the worst of farmers and the farming industry and that a_a's arguments, whilst appearing based in fact, are in fact no more than conjecture.

Unless a_a can provide direct proof that there is actually a problem with this method of food production I'll continue to assume that a_a has put the urge to get in a froth about animal rights ahead of the facts. And please don't assume that I don't care about animal rights, I do.

I was re-reading what I'd first written and just wanted to clarify one point. I said that the clones were

not... ...to be used in turn for further breading.

. I should not have suggested that they would never be used to breed from as this will definitely happen. However, I was trying to distinguish between the use of breeding to produce a better beast vs the reproduction of a single type of very high quality beast. From what I've hard it seems that the emphasis with the current use of cloning in beef is for the mass reproduction of high quality beasts.

At present
there are serious prenatal losses of cloned embryos and fetuses, especially in cattle and
other ruminants. Losses are still considerable during the neonatal period and serious
welfare problems can still occur up to 3?6 months. These losses will impact on the welfare
of the surrogate dam when there is a high incidence of dystocia and Caesarean section due
to ‘Large Offspring Syndrome’ in ruminants.

yum yum who's for corned beef fritters?

My understanding is that they clone top quality cattle and make the clones available for breeding. Essentially they are making more high quality breeding stock available at a lower price. So the overall quality of cattle is improved i.e. more and better milk and meat.

Arguably, this speeding up of the selection process reduces diversity in the gene-pool and makes the cattle population more vulnerable to extinctions from disease. But that's always the balance with any specialisation, whether it's evolutionary pressure, selective breeding, clones or whatever.

you really dont get it do you..............I give up

sorry cant leave it!!!
