Guest guest Posted January 27, 2003 Report Share Posted January 27, 2003 This came across my desktop today. best, pat More milk protein in Cloned cows A team in New Zealand say they have produced nine duplicate, transgenic calves whose milk boosted yields of two types of proteins by up to 100 per cent. 27/01/2003 SCIENTISTS have produced the world`s first genetically modified, cloned cows - a breakthrough that is set to become the latest controversy in the biotech business. A team in New Zealand say they have produced nine duplicate, transgenic calves whose milk boosted yields of two types of proteins by up to 100 percent. The two proteins help liquid cheese to solidify and expel whey, a by-product that is UNWANTED in cheese making. The researchers, led by Goetz Laible at Ruakura Research Centre in Hamilton, south of Auckland, say the technique offered " substantial economic gains " . It could be widened, to " tailor " milk for human consumption, they add. Scientists have genetically modified and cloned farm animals for medical research. But this is the first time a cow has been both engineered and cloned to produce an altered milk for human consumption. Dr Laible`s team inserted into a bovine cell two additional genes responsible for two casein proteins, beta and kappa. The modified cell was then fused with an egg whose core had been removed, the standard technique in cloning, and the embryo implanted into a cow uterus. Out of 126 transgenic, cloned embryos, just 11 (nine per cent) survived to become healthy, viable calves. That was even lower than the 20 per cent success rate among non-transgenic cloning, whose toll reflects the many risks from genetic duplication.

Guest guest Posted January 27, 2003 Report Share Posted January 27, 2003 I am surprised that they would do this... well both yes and no I guess. in Europe especially, people are rejecting genetically modified foods so I cannot see the milk or any byproducts doing well there. it might be a different story in the US where almost no one knows what GMF's are. I don't have much problem with the cloning as I do with the altered milk because I think that when you start playing around with things like that you can get in a real mess. People have already gotten sick when they mixed, I believe it was corn and soy together. They don't have to be labeled in the US though I believe that that is changing, so people with allergies didn't know to avoid these horrible products.... All it would have to say on the label is corn and those with soy allergies don't know about the soy component of the corn. And I know that they were trying to combine some aspect of a fish with a vegetable plant at one point. I think it's creepy and unnecessary. If they want to increase production and nutrients, they should find a way to "fix" the soil etc, not bio engineer things as they are doing. And just for the record, please don't think bio engineering is cross breeding, they are two separate things and many people get confused as to what the difference is.

Guest guest Posted January 27, 2003 Report Share Posted January 27, 2003 Hmmm, I wonder what kind of food labeling problems this will cause? Dave *****Pat posted.....
