Domestic goat as a species with a relatively great biodiversity of dairy breeds, which possess high genetic merit and yield of milk production, can be a valuable tool for embryo gene engineering. This involves the generation of transgenic specients, providing with xenogeneic (human) recombinant proteins (i.e. biopharmaceuticals), not only by the standard zygote intrapronuclear microinjection of gene constructs, but above all with the use of somatic cell cloning technology.
