Development of transgenic farm animals will allow more flexibility in direct genetic manipulation of livestock. Gene transfer is a relatively rapid way of altering the genome of domestic livestock.

"If, as in our experiments, the genetic change also reduces the offspring's ability to survive, a transgenic animal could bring a wild population to extinction in 40 generations." Extinction results ...

Transgenic animals, such as cows producing human therapeutic proteins in their milk, have also been created. Transgenic animals serve as valuable models for studying human diseases and testing new ...

Recent studies in transgenic mice support this conclusion ... spongiform encephalopathies (TSEs) in domestic cats and several other animal species fuelled concerns that BSE might have also ...
