Anyone looking in Animal Breeding: Technology for the 21st Century for
weapons to open a new phase in the battle over genetically engineered foods will
be disappointed. Instead, they will find a tool box of techniques for embryo
handling, gene analysis and gene manipulation which is still fairly crude. So it
will be many years before our fields are filled with transgenic livestock. Even
then these animals are less likely to be producing food than rather less
controversial medicinal products. Edited by A. J. Clark, Harwood Academic,
