To produce antibodies to fight cancer in humans.
To secrete human growth hormone to help dwarfs grow taller.
To produce eggs with lower cholesterol for human consumption.
To produce soy isoflavons in eggs sold for human consumption. For example, poultry researchers at the
University of Maryland and the University of Arkansas are experimenting with Japanese
quails to see if soy
isoflavons can be transferred and accumulated in their eggs.
To produce yolk antibodies,
specifically, avian immunoglobulin, or IgY,
for a range of diagnostic
systems as a substitute for the use of laboratory mammals.
As fertile “egg-type” hens‟ eggs carrying “meat-type” chicken cells in order to mass-produce cloned
“meat” (broiler) chickens, and thus do away with the expensive maintenance of broiler breeder flocks. In this
program, “certain individuals from the pedigree flocks would be cloned and the genetic material placed into
fertile eggs. Cloning companies would culture cells and then place them into the embryo of a fertilized recipient
egg forming a chick called a chimera. The recipient fertile eggs could come from flocks like
leghorns that
produce a large number of inexpensive eggs. When those eggs are hatched, they are broilers” [15].
In a typical condition, eggs also produce a large amount of ovalbumin in their reproductive tract that becomes
part of the egg. Transgenic eggs are engineered to secrete other types of protein into the egg so that they can be
easily isolated.
