New opportunities in animal breeding and production — an introductory remark

New opportunities in animal breeding and production will be offered by methods for embryo production and the introduction of precise genetic changes in livestock species. A review of current procedures shows that they have been improved during the last 4 years, but still have significant limitations. In the light of experience over the past 50 years it seems likely that these methods will contribute to animal health and productivity, but at some unknown time in the future and in ways that cannot be predicted precisely. When looking to the future, delegates to this meeting should take pride in what science continues to contribute.
