Andy, Here's a report from a Japanese group saying that they are using the same techique (genetically altered nucleus is placed in one egg and the nuclei from growing embryo are donors for additional enucleated eggs which are then implanted):

TOKYO (Reuter) - A Japanese farm group said Thursday it had developed new cloning technology that could produce up to 200 carbon-copy cattle from a single fertilised egg.

The National Federation of Agricultural Cooperative Associations in Japan said a cow gave birth Wednesday to a male calf produced using the new method, Japan's first home-grown cattle cloning technology.

The technique grows cultures of a fertilised egg, from which cell nuclei are taken and transferred to unfertilised eggs.

A federation official said cattle cloning technologies used previously in Japan have in practice been capable of producing only three to five head of cattle from a single fertilised egg.

``Developing cloning technology to produce cattle that can provide good milk and beef is very important to reducing costs and improving productivity in the livestock industry,'' the official said.

He added a calf has already been born in Wisconsin in the United States using a similar technology.
