FILE - This Friday, April 3, 2009 photo shows a trio of genetically altered kid goats at the goat barn at the University of California Davis, in Davis, Calif. The goats' genes have been modified so they they produce milk with a high concentration of a human enzyme that fights the bacteria that causes diarrhea. For thousands of years, humans have practiced selective breeding. That concept was refined to develop plant hybridization and artificial insemination. Now comes an Atlantic salmon that is genetically engineered to grow twice as fast as a regular salmon. If U.S. regulators approve it, the fish would be the first such scientifically altered animal to reach the dinner plate. less
