summarized research on cryopreservation
of avian genetic material and concluded that fertility
from cryopreserved semen is sufficiently high for
conservation purposes and that the technology around
primordial germ cells can be used in theory to cryopreserve
and recover avian germplasm but is too complex
and inefficient for practical use. The other option for
cryopreservation of avian germplasm
