Avian Specific Transgenesis

  • Michael J. McGrew
Reference work entry

Definition of the Subject

Transgenesis is the process by which an exogenous DNA molecule is incorporated into the genome of an animal. This technology promises the possibility to investigate and manipulate the production traits of poultry, produce recombinant proteins in the eggs of genetically engineered layer lines, and directly intervene in the health and welfare of avian species. The complexity of the avian egg and the precocious development of the avian embryo in the female before oviposition (laying) have hindered endeavors in avian transgenesis. Three decades of effort have been carried out to achieve the genetic modification of the avian genome. The generation of novel methods for the modification of the avian genome has led to the current advances in the field of avian transgenesis. This entry will delineate the methods used for avian transgenesis, the current state of the art, and the potential future directions research in this field will take.
