Cattle cloners face wary farmers

摘要

SYDNEY- An Australian breakthrough in cattle embryo cloning has scientists hailing the birth of a new industry- and farmers dismissing the advance as almost irrelevant and not even proper cleaning. A team of Melbourne geneticists has cloned 470 cattle embryos from a single embryo in the largest mass-cloning of embryos yet seen. Scientists behind the achievement hope to be in pilot commercial production of cloned animals in three to four years.
