Commercial aspects of cloning and genetic modification in cattle

Abstract

A range of potential commercial applications of cloning and genetic modification in cattle has been suggested over the last decade. It includes the rapid multiplication of elite genotypes, production of valuable human proteins, altered production characteristics, increased disease resistance and milk with improved nutritional value and processing capabilities. However, an economic return from the sale of product is far from reality in any of these areas. One impediment to achieving economic sustainability is the extremely low efficiency in producing healthy offspring from transferred cloned embryos. Other significant impediments are societal concerns surrounding such technologies, animal wel..
