That would be a valuable calf. But you would want to make many copies of it before you used the calf as a source of organs. The value of cloning mature animals then is not solely in prize milk cows or dairy bulls. Cloning is valuable when you already have something that is powerful but rare. Genetic engineering is the tool for making a valuable original.
Cloning is the way to make many copies of the original.
That's why ABS's subsidiary Infigen is negotiating with genetic engineering companies to link the new cattle cloning technology with gene transfer technology. Dolly bulldozed a paradigm of biology. ABS's Gene the Bull doesn't plow any paradigms. It demonstrates some new techniques of cell culture. It presents another set of recipes for cattle cloning.
